AB  - As a tobacco producer, Serbia has to deal with large amounts of leftover tobacco stalks after harvesting. One option for this type of biomass is to burn it, but burning is not encouraged in Serbia, since the levels of its combustion products have not been investigated yet. The aim of this study was therefore to determine the elemental composition, ash and nicotine content, heat values, and composition of gaseous combustion products of tobacco stalk briquettes and to see if their mixing with other types of biomass available in Serbia could improve their ecological profile. We made 11 different types of briquettes: six of pure raw materials, including burley tobacco stalks, sunflower head remains, wheat straw, corncob, soy straw, and beech sawdust and five by mixing tobacco stalks with these other raw materials in a 50:50 mass ratio. All briquettes meet the ecological criteria regarding the emission limits for nitrogen oxides (NOx), sulphur dioxide, carbon monoxide, and carbon dioxide. Nicotine content in flue gases (<10 mg/kg) is far below the maximum level allowed by the European Union. Heat values of all biomass samples are acceptable, although lower than those specified for solid biofuels (≥16.0 MJ/kg), save for corncob and beech sawdust and their mixtures with tobacco stalks. Our findings therefore encourage the use of tobacco stalks as a viable biofuel. © 2023 Maja Malnar et al., published by Sciendo.

from chemical and mechanical damages. Cigarette storage requires certain
conditions in terms of temperature, humidity and ventilation conditions, but there
is no clear recommendation on how much and how to store tobacco products. Even
if the recommended conditions are taken into account, which are very difficult to
fulfill, especially at points of sale, it is considered that tobacco products should not
be stored for more than one year. Expiration date of cigarettes is nowhere
regulated by law, in other words, they can be stored forever. However, even when
all storage conditions are met, due to the complexity of the product itself, its
composition may change. This paper started from the assumption that cigarettes,
which have been stored for 10 years in inadequate conditions, are not suitable for
use.

AB  - Technological properties of tobacco that determine its usability are variable, so the quality of tobacco and tobacco products depends on the interaction of type and variety genetic properties on the one hand and agroecological growing conditions on the other.The aim of this experiment was to determine the influence of agroecological conditions on the smoke sensory properties of Burley tobacco type from experimental plots in five production areas in Serbia: Senta, Čoka, Šabac, Bajina Bašta and Vranje, during 2013. Hydrometeorological conditions data for vegetation period were taken from the Republic Hydrometeorological Service of Serbia. The analysis of soil and basic chemical properties of first class middle leaves tobacco, after air curing and leaf processing, was performed using standardized methods. Cigarettes were made and the sensory characteristics of smoke (physiological strength, taste and aroma of tobacco smoke, fullness of smoking and cigarette combustion) were determined, using the key for sensory evaluation of quality according to Sozonović. The best sensory characteristics were determined in Berlej from the production area of Šabac, and the worst from the area of Vranje. Šabac as a region had the most uniform temperatures and the least amount of precipitation in the vegetation period; the soil had the highest pH value and contains a significant amount of organic matter. Vranje as a region had the lowest temperatures and the highest amount of precipitation in the vegetation period; the soil had the lowest pH value and the lowest content of organic matter. Growing conditions had an impact on the smoke sensory properties through the accumulation of chemical components in the tobacco leaf, since the same agro technical measures were performed in all five production areas. Agrotechnical measures that are adapted to the production area characteristics could reduce the impact of agroecological conditions to a minimum, which would enable the production of tobacco with better technological properties.

AB  - In order to reduce the harmful effects of cigarette smoke on the health of active and passive smokers, a new tobacco product - Tobacco heating system (THS) has been developed. Heating, rather than burning tobacco reduces the level of harmful and potentially harmful ingredients in the aerosol. New products are compared to cigarettes, because cigarettes are the most represented and most tested tobacco product on the market. This study aimed to compare the new THS product - IQOS (HEETS cartridges) and the Marlboro cigarette from the same manufacturer, which were available on the Serbian market. The physical characteristics of both products, the chemical characteristics of the aerosols and the amount of heavy metals in the aerosol were analyzed using standardized methods. Measurements were made in three replicates. The physical characteristics of the product showed that HEETS was 2.2 times shorter than a cigarette, 1.95 mm smaller in diameter and 25% less in weight than a cigarette. The content of total particulate phase (TPM) was reduced by 72.19%, nicotine by 30.99%, and the amount of TAR by 98.85% in HEETS condensate in relation to cigarette. Aerosol chemical analysis results indicate that the new THS product offers a lower health risk compared to traditional cigarettes consumption.

AB  - Often referred to as worlds’ second most valuable commodity, coffee is produced in fifty countries and subsequently consumed worldwide generating a great amount of waste. Among their many other applications, this paper provides a survey of coffee by-products utilization in food industry. Coffee pulp is used to obtain volatile compounds and acetic acid by microbial activity. It can also be a source of anthocyanins, acting as natural colorants and bioactive ingredient. Recently, coffee pulp flour with high fiber (18%) and mineral (8%) content has been developed for application in confectionery and baked products. Various food additives (pectins, antioxidants and colors) can be obtained from mucilage, and even coffee honey was extracted from it. Husk is a source of citric acid and natural flavour. Silver skin has been used in combination with other ingredients in producing innovative coffee blends, bread, and biscuits, which had improved sensory and nutritional composition and reduced amount of hydroxymethylfurfural and acrylamide. Spent coffee grounds (SCG) has been used for obtaining a distilled beverage with coffee aroma and bioactive extract enriched in caffeine. Due to melanoidins content, it also exhibits an antimicrobial effect on some pathogens, such as S. aureus and E. coli. Being rich in dietary antioxidant fiber, SCG is incorporated in diverse food formulations with low glycemic and energetic value. A mixture of all coffee industry by-products is used as substrates for edible mushroom cultivation. Therefore, coffee waste, as an abundant natural material with low value, has a great potential of transferring into beneficial food products.

AB  - Raw tobacco production in the world has a long tradition and is widespread throughout the
continents. Due to polymorphism as one of its most prominent traits, tobacco has adapted to
all conditions under which it is grown. In addition to natural conditions, the most important of
which are soil type and climate, raw tobacco production is also influenced by economic
factors, such as the world market price of tobacco, government support and global anti-
smoking policies. The aim of this paper is to present and analyze tobacco growing and
turnover in Serbia, based on the collected data and information. The importance of the paper
is in recognizing the structure and dynamics of production and marketing, as well as their
causes, primarily because the production of this species brings significant economic benefits
to the state, both through the realization of the products themselves, as well as through the
creation of new jobs and income from taxes. The statistical data of the Statistical Office of
Republic of Serbia, as well as the research results of the place and role of tobacco production
in Republic of Serbia, served as the main source of data in the preparation of this paper. The
data was analyzed using mathematical and statistical analysis, while relative dynamics
indicators, baseline indices and average growth rates were used to demonstrate the status,
changes and potential in tobacco production in Republic of Serbia.

causes, primarily because the production of this species brings significant economic benefits
to the state, both through the realization of the products themselves, as well as through the
creation of new jobs and income from taxes. The statistical data of the Statistical Office of
Republic of Serbia, as well as the research results of the place and role of tobacco production
in Republic of Serbia, served as the main source of data in the preparation of this paper. The
data was analyzed using mathematical and statistical analysis, while relative dynamics
indicators, baseline indices and average growth rates were used to demonstrate the status,
changes and potential in tobacco production in Republic of Serbia.",

AB  - Tobacco production in Republic of Serbia today includes two types of tobacco because Oriental tobacco has no longer been produced since 2016. The aim of this experiment was to determine the influence of agroecological conditions on the chemical properties of Burley tobacco from five different production areas in Serbia during 2013. First class middle leaves of Burley tobacco from Senta, Čoka, Šabac, Bajina Bašta and Vranje municipalities/towns were used as research material. Analysis included the characterization of soil (pH value and organic matter) and determination of following tobacco chemical components: total proteins, nicotine, reducing sugars, pH and ash. All analyzes were performed by standardized methods in three replications. Hydrometeorological conditions data for vegetation period were taken from the Republic Hydrometeorological Institute of Serbia. The results showed that agroecological conditions of growing had an influence on the amount of chemical components, since the same agrotechnical measures were applied in all five production areas and the same amount of fertilizer was used. The positive correlation between nicotine content and the air temperature and percentage of organic matter in the soil was determined, as well as the negative correlation with the amount of precipitation. Tobacco protein content showed positive correlation with pH value of soil and negative correlation with the amount of precipitation. In addition to that, the positive correlation was found between the sugar content of tobacco and the air temperature and soil pH value, while sugar content was in negative correlation with the amount of precipitation. The ash content and the pH value of tobacco increased with the pH and percentage of soil organic matter, but decreased with the amount of precipitation.

AB  - Due to the popularization of waterpipe smoking, the differences in the smoking protocols, differences in the mixture composition and the assumption that its smoke is less harmful than cigarette smoke, it is necessary to continuously carry out the chemical composition of smoke. Main goal of this research was to define how composition of tobacco mixture (tobacco, glycerin, glucose syrup, aroma), which is combusted in waterpipe, influences on basic components in particulate phase of smoke.The protocol of smoking session in laboratory conditions was based on researches performed on belgrade's waterpipe caffes and it represents the average smoking behavior of consumers. The mainstream smoke generation and sampling of particulate phase are performed on Smoke Collection System with Vacuum. The determination of smoke components is performed in accordance with ISO. The results showed that mixture's composition has a significant influence on formation of particulate phase in the waterpipe mainstream smoke. There was a statistically highly significant correlation between tobacco, glycerin and glucose syrup amounts in the mixture and tested characteristics of WTS. Aroma has no statistically significant influence on the components in particulate phase of the mainstream smoke. An important conclusion is that the mixture components such as glycerin and sugar components, which provide authenticity and specificity of the waterpipe mixture, actually additionally increase the harmful effects of smoke. However, it would be difficult to maintain taste characteristics with radically decreased amount of materials which are mentioned above.

AB  - Virginia type of tobacco is used in the highest percentage in the mixture for making
cigarettes. Important factors for the formation of quality features of Virginia are
environmental conditions of manufacturing but preferably the well regulated drying process.
Drying of these tobacco types is performed in special dryers with controlled conditions (flue
curing-FC). Since the price of energy source for drying process participate the greatest deal in
total expenses during the production and processing of tobacco, the scope of the experiment
was to determine the possibilities of drying tobacco in a natural condition (air curing-AC).
Material for research the first-class middle leaves of Virginia tobacco type, variety Heveshi -
9, were produced in Vojvodina area (Srem - Maradik), vintage 2015.
The experimental results showed that the way of drying affects the appearance and color of
leaves, chemical characteristics of tobacco and duration of the drying process. Considerable
differences of chemical composition between flue curing and air curing tobacco were found as
follows (% in dry matter): 2.03 and 2.25 (nicotine), 1.80 and 2.73 (total N), 0.87 and 2.06
(protein N), 5.46 and 6.60 (total proteins), 19.39 and 1.96 (reducing sugars), 11.61 and 15.43
(ash), 1.48 and 8.91 (sand), 5.19 and 5.92 (pH), respectively. The leaves dried in natural
condition (AC) had dark color (dark Virginia) and rough nervature. Although drying in a
natural condition brings cost savings in energy, the process is longer by 24 days comparing to
flue curing.

AB  - Due to the rise of industrialization and urbanization, the amount of waste is gradually increasing as well, both in developed and developing countries. Tobacco waste generates in all processes it starts in the field and ends up with the production of cigarettes. The total global tobacco waste production in the year 2005 was more than 25.1 million tons. In our experiments we used Virginia tobacco waste (TW) after processing, as well as sheep and chicken droppings. Two experimental samples were formed according to the following scheme: I 50% TW + 50% sheep droppings, II 50% TW + 50% chicken droppings. The comparison is made with the reference sample (100% TW). The experiment was conducted at the experimental farm of the Faculty of Agriculture, under natural conditions, in the open, during the three months period. The nicotine content in the samples was determined by a HPLC method. At the beginning of the experiment, the nicotine content in the tobacco waste was 17 363 mg/kg. By adding sheep and chicken droppings, nicotine content decreased by 66,5%. At the end of the research, nicotine content was dropped below 10 mg/kg in both experimental samples. The results confirmed that the organic material, sheep and chicken manure, can be successfully used for composting tobacco waste, primarily in order to reduce the nicotine content. Composting can be done in the open air and on the site where the waste is made, thereby it reduces energy costs, and what's the most important - the costs of transport.

AB  - The reduction of world`s fossil fuel reserves, as well as concern environmental pollution,
encourages the use of renewable energy sources. In the Republic of Serbia, biomass from
agriculture represents a significant energy potential. The aim of this paper was to examine the
possibility of using tobacco stalks as biofuels, considering that each year, after the harvest of
leaves, about 70 000 tons of stalks from all tobacco types remains in the fields. The material used
in this study were Burley tobacco stalks, sawdust from beech wood and wheat straw, which were
chosen due to the fact that they are already in use as biofuel. In the first part of the experiment the
ash content in all samples was determined, which is used to predict the higher heating value
(HHV). The HHV as a function of ash content (ash, wt %) was calculated using the equation by
Sheng and Azevedo. The experimental determination of the calorific value of all samples in a
calorimetric bomb was conducted in the second part of the study. Based on predicted (18208.18
kJ/kg) and experimentally determined HHV of tobacco stalks (17504.44 kJ/kg), as well as
comparisons with other forms of biomass, it was concluded that Burley tobacco stalks can be
used as biofuel. Experimental values of tobacco stalks are only 9% lower in relation to HHV of
beech sawdust. Tobacco stalks and wheat straw have the approximate values of HHV.

ash content in all samples was determined, which is used to predict the higher heating value
(HHV). The HHV as a function of ash content (ash, wt %) was calculated using the equation by
Sheng and Azevedo. The experimental determination of the calorific value of all samples in a
calorimetric bomb was conducted in the second part of the study. Based on predicted (18208.18
kJ/kg) and experimentally determined HHV of tobacco stalks (17504.44 kJ/kg), as well as
comparisons with other forms of biomass, it was concluded that Burley tobacco stalks can be
used as biofuel. Experimental values of tobacco stalks are only 9% lower in relation to HHV of
beech sawdust. Tobacco stalks and wheat straw have the approximate values of HHV.",

AB  - Plants are autotrophic organisms which are able to use sunlight and carbon dioxide as the sources of energy and carbon. Plants' roots absorb a range of natural and anthropogenic toxic compounds for which they have developed some extraordinary detoxification mechanisms. From this point of view, plants can be seen as natural, solar-powered pump-and-treat systems for cleaning up contaminated soils, leading further to the concept of phytoremediation. The phytoremediation of polycyclic aromatic hydrocarbons (PAHs) refers to the use of plants and associated soil microorganisms in terms of reducing the concentrations or toxic effects of these contaminants in the environment. Although there is little evidence to prove that PAHs from soils are accumulated considerably in plants' parts, there is a lot of evidence that in soils vegetated with grasses and legumes, a significant dissipation of PAHs occurs. Namely, the primary mechanism controlling this process is the rhizospheric microbial degradation, where soil microbial populations use organic compounds as carbon substrates for its growth. This is usually stimulated by roots exudates. The final result of this process is the breakdown and eventual total mineralization of the contaminants. The main challenge in PAH phytoremediation is to improve the performances of plants and rhizospheric microorganisms requiring thus more basic research and knowledge on natural detoxification mechanisms.

AB  - The aim of this study was to determine the influence of particular element of the minerals complex in Virginia tobacco, from different production areas, on value of static burning rate (SBR). Large leaf tobacco, type Virginia from five production areas in Serbia during year 2013, was used as a research material. Mineral content was determined by the atomic absorption spectrophotometer. Static burning rate was determined by the device Free Burning Rate Meter. Result: had confirmed that the most important facto for mineral matter content in tobacco leaves are soil pH, organic matter content in soil and vicinity of large industrial centers. A very strong positive correlation between the content of Ca and Pb, a positive correlation of Mg and Na, and a strong negative correlation of Cd and both SBR values has been found. Virginia tobacco type grown at Senta area had the highest values for both speeds of combustion (4.99 mm/min for SBR1 and 69.97 mg/min for SBRm). Virginia tobacco type grown at Sremska Mitrovica area had the lowest values for both speeds of combustion (3.95 mm/min for SBR1 and 49.11 mg/min for SBRm).

AB  - Most of the recent studies, performed in order to estimate the potential value of biomass for energy production, were done on common biomass resources such as corn, wheat, sunflower, barley and oats. Although tobacco stalks are rarely or almost not used for this purpose, according to their chemical composition and heating value, they can be classified as non-toxic agricultural waste, which makes them a renewable energy source. According to the statistics in agricultural production, Serbia has a great potential in tobacco stalks which are treated as agricultural waste and they are not used for energetic purposes. This paper deals with two common types of large leaves tobacco stalks in this region; Virginia and Burley, as a potential renewable energy source. The heating values were calculated according to the elemental chemical composition and lignin content, and compared with other known agricultural waste. Various equations for high heating value calculation were taken in account in order to present tobacco stalks as renewable energy source. Results of analysis showed good agreement of tobacco stalks heating values in comparison with other crops, and does not deviate significantly from other agricultural waste.

AB  - The aim of this study was to examine the impact of three main tobacco types (flue-cured FC, air-cured AC and sun-cured SC) and two tobacco-based materials (reconstituted tobacco - recon RT and expanded stem) on the formation of carbon monoxide (CO) in the gas phase of mainstream cigarette smoke. The results showed that the type of tobacco examined had a significant impact on the amount of carbon monoxide production in the gas phase of cigarette smoke. AC and SC tobaccos had the most evident impact. The amount of tobacco in mixtures M-1, M-2 and M-3 as well as the addition of expanded stems had an impact on the amount of CO formed in the cigarette smoke. There is weak correlation between CO content in the smoke and the chemical composition of the tobacco. Draw resistance had an impact on CO production. The research results are of great importance, since tobacco selection is the first step in the production of cigarettes with reduced emission of harmful elements contained in the smoke.

AB  - Tobacco stalks are an under-utilized material that remains after the harvest of leaves. Given the share of large leaf tobacco in total production in Serbia (more than 85%) stalks could be easily available as well as payable raw material in the fabrication of cellulose. The aim of this study was to determine cellulose content in leaves and more importantly in stalks of large leaf tobacco and to provide necessary data to processors engaged in processing of biomass. Stalks and leaves of two types of tobacco, Burley and Virginia, reared in Srem, were used as experimental material samples. Two parallel methods were applied for determining cellulose content: method by Kürschner-Hanack and method by Updegraff. It can be concluded that both methods are applicable to tobacco, but the method by Kürschner-Hanack was found to be simpler, more convenient, faster and economically more cost-effective. Thus, it should be recommended for use. Results showed that stalks of large leaf tobacco contain on average 30.50% to 34.30% of cellulose. There was no statistically significant difference in the cellulose content between the two applied methods. Given the number of plants that lag behind in fields after harvesting leaves, 28,000 tons of cellulose could be used.

AB  - There are certain opposites in the relation of economy and ecology, but at the present days the ultimate task is to realize reciprocity between them. The interaction between economy and nature has come to the phase which demands permanent tracking, and action as well. This is a necessity not only due to the restricted natural resources, but primarily due to the releasement of waste materials which exceeds the absorption capacity of global environment. Every responsible economy has to develop strategies of environmental protection and sustainable development. These strategies have to be based on objective, and professionally determined state, economic and law principles. Recently, an increasing public concern and a scientific investigations have been focused on the occurrence of PAHs and their control in air, water, soil, and herbal and animal products. Polyciclyc Aromatic Hydrocarbons (PAHs) are a class of several hundred diverse compounds usually containing two to seven fused benzene rings. They belong to a special group of ubiquitous contaminants known as Persistent Organic Pollutants (POPs), which are subject to long-range atmospheric transport (LRAT), and most can be photo-oxidized and degraded to simpler substances, which is very important for their distribution and fate in the environment and biota. PAH exposure through air, water, soil, tobacco smoke and food sources, occurs on a regular basis for most people. Routes of exposure include ingestion, inhalation, and dermal contact in both occupational and non-occupational settings. It was essential, in order to protect public health, and environment in general, to keep these contaminants, which are considered to be genotoxic carcinogens, at levels which are toxicologically acceptable. Maximum levels in foodstuffs, water, and air have been set at a strict levels by specific agencies in many countries. The 16 PAHs are included in the list of priority pollutants in EU: benzo(a)pyrene (BaP), cyclopenta(c,d)pyrene (CPP), indeno(1,2,3-cd)pyrene (IcP), benzo(c)fluorene (BcL), benzo(a)anthracene (BaA), chrysene (CHR), 5-methylchrysene (5MC), benzo(b)fluoranthene (BbF), benzo(j)fluoranthene (BjF), benzo(k)fluoranthene (BkF), benzo(g,h,i)perylene (BgP), dibenzo(a,h)anthracene (DhA), dibenzo(a,e)pyrene (DeP), dibenzo(a,h)pyrene (DhP), dibenzo(a,i)pyrene (DiP) and dibenzo(a,l)pyrene (DlP). The most known potent carcinogen, benzo(a)pyrene, is commonly used as an environmental indicator for PAHs. A recent directive of the European Commission (The Commission of the European Communities) uses BaP as a marker for the carcinogenic risk of PAHs and sets a limit value for this toxicant, to be attained as far as possible 1 ng/m3. The carcinogenicity of BaP and of other PAHs is well established in laboratory animals. Researchers have reported incidences of skin, lung, bladder, liver, and stomach cancers, in animals. Animal studies showed that certain PAHs also can affect the immune systems and produce reproductive, neurologic, and developmental effects.

abstract = "There are certain opposites in the relation of economy and ecology, but at the present days the ultimate task is to realize reciprocity between them. The interaction between economy and nature has come to the phase which demands permanent tracking, and action as well. This is a necessity not only due to the restricted natural resources, but primarily due to the releasement of waste materials which exceeds the absorption capacity of global environment. Every responsible economy has to develop strategies of environmental protection and sustainable development. These strategies have to be based on objective, and professionally determined state, economic and law principles. Recently, an increasing public concern and a scientific investigations have been focused on the occurrence of PAHs and their control in air, water, soil, and herbal and animal products. Polyciclyc Aromatic Hydrocarbons (PAHs) are a class of several hundred diverse compounds usually containing two to seven fused benzene rings. They belong to a special group of ubiquitous contaminants known as Persistent Organic Pollutants (POPs), which are subject to long-range atmospheric transport (LRAT), and most can be photo-oxidized and degraded to simpler substances, which is very important for their distribution and fate in the environment and biota. PAH exposure through air, water, soil, tobacco smoke and food sources, occurs on a regular basis for most people. Routes of exposure include ingestion, inhalation, and dermal contact in both occupational and non-occupational settings. It was essential, in order to protect public health, and environment in general, to keep these contaminants, which are considered to be genotoxic carcinogens, at levels which are toxicologically acceptable. Maximum levels in foodstuffs, water, and air have been set at a strict levels by specific agencies in many countries.

AB  - Reduction of harmful tobacco smoke compounds, such as nitrosamines and polycyclic aromatic hydrocarbons (PAHs) could be particularly controlled by adjusting the cigarette pyrolitic conditions. One possible way to do that is by adding zeolite materials directly to the cigarette. In this work two types of zeolites, namely, pentasil ope (ZSM-5) and Y type were used, both in the quantity of 3% in respect to the tobacco mass. The results of the experiment have shown that both zeolite types influenced the changes in pyrolitic temperatures, as well as that both zeolites were catalytically active and that as the outcome of that activity there were changes in conditions of the burning process. It was concluded that the type of zeolite had more influence on the temperatures of the gas phase than on the temperatures of the solid phase. Actually, adding the two zeolite types resulted in a decrease of temperatures in both the solid and gas phase, while the decrease was higher when the zeolite of pentasil type was added.

AB  - Tobacco smoke is complex aerosol with more than 4800 compounds which are responsible for physiological as well as sensory properties of smoke. But some of these substances are considered as a harmless for the smoker's health and some of them are cancer promoters. Nicotine, TAR and CO is the ones indicated as a very dangerous. Nowadays cigarette design assumes reduction of these compounds in smoke. One of the possibility often use for reduction is filtration of tobacco smoke with various type of filters. Efficiency degree of aceto-celulosic filters with addition of specific filtration materials-zeolites has been investigated. The aim was determination of influence of type (crystal and amorphous) and way (longitudinal and segment) of zeolite application upon filter efficiency and sorption capacity. All types of zeolites were added in the quantity of 60mg per cigarette. Standard CORESTA and ISO methods determined composition of tobacco smoke. Filtration of tobacco smoke is more efficient if the zeolites are applied longitudinal. The best efficiency was by the filter made with the amorphe zeolites added longitudinal up to 93,10% regarding to the particular compound. With the samples where the zeolites were granulated with glue the additional increscent of filter efficiency - 62,32% has been detected, in correlation of the type of compound in smoke.

AB  - Na osnovu rezultata dobijenih našim istraživanjima, mogu se izvesti sledeći zaključci: 1. Temperaturni uslovi za razvoj i sazrevanje duvana u područjima u kojima su postavljeni ogledi, bili su u optimalnim granicama. Na osnovu vrednosti temperatura (tabele 1 i 2) može se zaključiti da područje Šapca pruža najbolje uslove za proizvodnju duvana (srednja temperatura u vegetacionom periodu je 22,2 - 22,8oC u 1998 godini). 2. Sume padavina i relativna vlaga vazduha variraju, kako po proizvodnim područjima tako i po godinama posmatranja. Eksperimentalno je dokazano da ni ekstremno velike količine padavina, koje su karakterisale 1999 godinu, nisu obezbedile potrebne količine vode po jedinici površine. Drugim rečima, ni jedno proizvodno područje nema dovoljnu količinu padavina, koja je neophodna pri proizvodnji krupnolisnih duvana. U pogledu relativne vlage vazduha, sva proizvodna područja odgovaraju proizvodnji krupnolisnih duvana. Najviše vrednosti zabeležene su na području Sente (84-87%) u 1998 godini i Šapca (79-82%) u 1999 godini. 3. Degustacionom analizom virdžinije ustanovljeno je da najbolje karakteristike ima duvan sa proizvodnog područja Šapca, obe berbe, a zatim sa proizvodnog područja Sremske Mitrovice. Za ostala porekla može se reći da su u granicama degustacionih vrednosti za dati tip duvana. Zajednička karakteristika za sva porekla je slabije izražena fiziološka jačina 1999 godine. Ova pojava je posledica intenzivnih padavina, usled čega se dobar deo đubriva sprao u donje slojeve zemljišta, pa je usvajanje hranljivih materija, pre svega azota, bilo manje intenzivno. S druge strane razlaganje azotnih materija je intenzivirano u uslovima povećane vlažnosti. Na osnovu iznetih podataka sa sigurnošću se može reći da svih pet ispitivanih proizvodnih područja imaju uslova za proizvodnju krupnolisnih duvana, odnosno daju sirovinu čija su tehnološka svojstva u granicama karakterističnim za krupnolisne duvane, ukoliko bi se obezbedili adekvatni uslovi gajenja. Pri tome treba naglasiti da optimalne uslove ima proizvodno područje Šapca, jer je ovde proizvedena virdžinija sa najkvalitetnijim tehnološkim karakteristikama. - Uticaj uslova gajenja na tehnološka svojstva krupnolisnih duvana je evidentan. Pri tome, direktan je uticaj ekoloških uslova na hemijske karakteristike i sadržaj mineralnih materija, kao osnovnih tehnoloških karakteristika a preko njih, dakle indirektno, na degustacione karakteristike duvana. - Imajući to u vidu, određenim agrotehničkim merama (pri tome se pre svega misli na omogućavanje adekvatnog navodnjavanja u zavisnosti od potrebe određenog tipa duvana za vodom primenu tačno određene količine đubriva i obavezno zalamanje), mogli bi regulisati uticaj uslova gajenja na proizvodnju i tehnološka svojstva duvana, odnosno agrotehničkim merama svesti pomenuti uticaj na najmanju meru. U tom slučaju, sa sigurnošću bi se moglo očekivati da bi se proizvela sirovina sa daleko boljim tehnološkim karakteristikama, a sve u cilju dobijanja kvalitetnog finalnog proizvoda, odnosno cigarete.

abstract = "Na osnovu rezultata dobijenih našim istraživanjima, mogu se izvesti sledeći zaključci: 1. Temperaturni uslovi za razvoj i sazrevanje duvana u područjima u kojima su postavljeni ogledi, bili su u optimalnim granicama. Na osnovu vrednosti temperatura (tabele 1 i 2) može se zaključiti da područje Šapca pruža najbolje uslove za proizvodnju duvana (srednja temperatura u vegetacionom periodu je 22,2 - 22,8oC u 1998 godini). 2. Sume padavina i relativna vlaga vazduha variraju, kako po proizvodnim područjima tako i po godinama posmatranja. Eksperimentalno je dokazano da ni ekstremno velike količine padavina, koje su karakterisale 1999 godinu, nisu obezbedile potrebne količine vode po jedinici površine. Drugim rečima, ni jedno proizvodno područje nema dovoljnu količinu padavina, koja je neophodna pri proizvodnji krupnolisnih duvana. U pogledu relativne vlage vazduha, sva proizvodna područja odgovaraju proizvodnji krupnolisnih duvana. Najviše vrednosti zabeležene su na području Sente (84-87%) u 1998 godini i Šapca (79-82%) u 1999 godini. 3. Degustacionom analizom virdžinije ustanovljeno je da najbolje karakteristike ima duvan sa proizvodnog područja Šapca, obe berbe, a zatim sa proizvodnog područja Sremske Mitrovice. Za ostala porekla može se reći da su u granicama degustacionih vrednosti za dati tip duvana. Zajednička karakteristika za sva porekla je slabije izražena fiziološka jačina 1999 godine. Ova pojava je posledica intenzivnih padavina, usled čega se dobar deo đubriva sprao u donje slojeve zemljišta, pa je usvajanje hranljivih materija, pre svega azota, bilo manje intenzivno. S druge strane razlaganje azotnih materija je intenzivirano u uslovima povećane vlažnosti. Na osnovu iznetih podataka sa sigurnošću se može reći da svih pet ispitivanih proizvodnih područja imaju uslova za proizvodnju krupnolisnih duvana, odnosno daju sirovinu čija su tehnološka svojstva u granicama karakterističnim za krupnolisne duvane, ukoliko bi se obezbedili adekvatni uslovi gajenja. Pri tome treba naglasiti da optimalne uslove ima proizvodno područje Šapca, jer je ovde proizvedena virdžinija sa najkvalitetnijim tehnološkim karakteristikama. - Uticaj uslova gajenja na tehnološka svojstva krupnolisnih duvana je evidentan. Pri tome, direktan je uticaj ekoloških uslova na hemijske karakteristike i sadržaj mineralnih materija, kao osnovnih tehnoloških karakteristika a preko njih, dakle indirektno, na degustacione karakteristike duvana. - Imajući to u vidu, određenim agrotehničkim merama (pri tome se pre svega misli na omogućavanje adekvatnog navodnjavanja u zavisnosti od potrebe određenog tipa duvana za vodom primenu tačno određene količine đubriva i obavezno zalamanje), mogli bi regulisati uticaj uslova gajenja na proizvodnju i tehnološka svojstva duvana, odnosno agrotehničkim merama svesti pomenuti uticaj na najmanju meru. U tom slučaju, sa sigurnošću bi se moglo očekivati da bi se proizvela sirovina sa daleko boljim tehnološkim karakteristikama, a sve u cilju dobijanja kvalitetnog finalnog proizvoda, odnosno cigarete.",

AB  - In the production of the so−called "safe cigarette", attention has been focused so far on the particle phase of tobacco smoke and possibilities of reducing its harmful components (tar, nicotine and PAHs). CO, an element of the gas phase of tobacco smoke, is still considered a minor by−product. The exploited technical and technological solutions concentrate on nonselective removal of the particle phase (filtration and perforations of cigarette paper). However, these solutions face numerous technological limitations such as suction resistance in the case of filtration and tearing resistance in the case of paper perforations. Methods based on tobacco smoke modification by selective removal of undesirable components are still in pilot phase. Such methods, aimed at reduced generation of harmful components, involve changes in combustion conditions and temperature achieved by adding specially synthesized catalysts into the tobacco blend. The active surfaces of these catalysts adsorb the already formed undesirable components of tobacco smoke.
AB  - Prema najnovijim podacima više od 1 svetske populacije konzumira cigarete (oko 1,7 milijardi ljudi). Dnevna potrošnja cigareta u svetu je oko 16,5 milijardi komada. Obzirom da konzumiranje cigareta raste iz godine u godinu novi zakonski propisi u proizvodnji cigareta nameću sve rigoroznije zahteve u pogledu materija štetnih po zdravlje u duvanskom dimu. Ovaj rad ima za cilj da se našoj naučnoj i stručnoj javnosti prezentiraju rezultati, koji se kod nas i u svetu postižu u cilju smanjenja štetnih efekata duvanskog dima cigarete. Rad se bazira na literaturi koja se bavi elementima štetnosti duvanskog dima po zdravlje aktivnih i pasivnih pušača, kao mogućnošću smanjenja štetnih elemenata duvanskog dima cigareta.

AB  - The aim of this work was to examine the influence of growing conditions on heavy metal content in virginia (flue cured) and burley (air cured) tobacco type. Moreover, some of these metals could appear in the tobacco cigarette smoke. This fact may cause negative consequences for cigarette consumers. Examinations were carried out in five various production areas, for each tobacco type, during two years, 1998 and 1999; those were extreme years for production.	Considering the results, it can be concluded: The most important factor for heavy metal content in tobacco leaves are weather conditions especially the amount of rainfall, since there is a direct correlation between the rainfall and size of roots, a dominant vegetation organ. It is inevitable that the metals content in flue cured and air cured tobaccos grown at different experimental lots, is still below the legally prescribed values. Tobacco leaves from Šabac production area have a little higher metal content than tobacco grown in other production areas, because a larger amount of copper was found. The metal content in plants can increase because of its absorption from soil, atmosphere, or mineral fertilizers and pesticides, and, what is very important, the content of metals can be high due to the vicinity of large industrial centers.
AB  - Poznato je da su metali prisutni u biljkama u količinama koje zavise od vrste biljke, klime i drugih faktora. Cilj ovog rada je ispitivanje direktnih uslova gajenja na sadržaj teških metala u duvanima tipa virdžinija, sorta Heveši-9 i tipa berlej, sorta B-92. Neki od ovih metala mogu da pređu u duvanski dim cigarete, što može imati neželjene posledice za pušača. Ispitivanja su vršena u po 5 različitih proizvodnih područja Srbije, za svaki tip duvana, tokom dve godine, 1998. i 1999., koje su bile ekstremne za proizvodnju duvana. Sumirajući rezultate dvogodišnjih istraživanja možemo zaključiti sledeće: Upotreba NPK đubriva nije imala uticaja na sadržaj teških metala u duvanima. Od klimatskih faktora, na sadržaj teških metala u duvanu najveći značaj imaju padavine. Usled različite količine padavina dolazi do razlike u ekspanziji korena biljaka, pa su posledica toga različite količine mikroelemenata, koje se preko korena asimiluju. Duvani iz proizvodnog područja Šapca, sadrže bakar u koncentracijama nešto većim od dozvoljenih za duvan, kao i nešto više vrednosti sadržaja ostalih teških metala u odnosu na duvan gajen na drugim lokalitetima. Na ovu pojavu bi mogla da utiče blizina industrijske zone, kao i sastav zemljišta i primena zaštitnih sredstava.
