AB  - In suburban Belgrade, there are some 200 local water supply systems which are not connected to either the Belgrade Water Supply System or to supply systems operated by municipal utilities. The small systems in Belgrade suburbs are either operated by local municipality (local government) or even by the group of local citizens who have neither technical capability nor financial resources to do it properly. Roughly 200,000 of Belgrade's inhabitants obtain their drinking water from these water supply systems. The water quality delivered by these local water supply systems is often compromised in terms of microbiological, physical and/or chemical compliance with drinking water standards in addition to the general lack of strategy on water safety plans and risk assessment. WHO Guidelines on water quality standards as well as the recommendations on safety plans and whole risk assessment are strictly respected in the main (central) Water Supply System in Belgrade. Most frequently, elevated concentrations of ammonia, nitrites, nitrates and iron lead to lack of chemical compliance, while elevated counts of aerobic mesophilic bacteria and the presence of bacteria indicative of faecal pollution tend to be behind microbiological lack of compliance with drinking water standards. In most cases, failure to meet drinking water standards can be attributed to groundwater pollution. No sewer system exists in these areas, and wastewater from septic tanks, in practice infiltration wells, is in direct contact with groundwater. Of a total of 72 laboratory-tested drinking water samples, 51.3% failed to meet physical and/or chemical standards, and 73.6% failed to meet microbiological standards. Groundwater pollution can only be prevented if wastewater disposal system is provided for all households and all suburban residential areas which obtain their water supply from local water supply systems. Some possible mitigation measures have been indicated. In the interim period, water must be disinfected continually, and the feasibility of ozonation or UV irradiation, in addition to chlorination, should be assessed.

AB  - Investigations were performed on soils of different acidity, ranging in the pH interval 4.65-5.80 (in water). Changes of the mineral nitrogen forms in the examined soils were studied by applying short-term incubation experiments performed under aerobic conditions, with a humidity of 30 % and a temperature of 20°C, both with and without the addition of 100 and 300 ppm NH4-N. The results of the incubation experiments showed that retarded nitrification was present in all the examined soils. Increased and toxic quantities of nitrites (35.7 ppm) were formed during the incubation, which remained in the soil solution for several days, and even weeks, in spite of favorable conditions of moisture, aeration and temperature for the development of the process of chemoautotrophic nitrification. Decelerated chemoautotrophic nitrification was the source of the occurrence of nitrite in the examined less acid soil (soil 1), while in soils of higher acidity (soils 2 and 3) after addition of 100 and 300 ppm NH4-N, nitrite occurred due to chemical denitrification (chemodenitrification). Nitrites formed in the process of chemodenitrification underwent spontaneous chemical oxidation resulting in nitrate formation (chemical nitrification). The content of mineral nitrogen (NH4 + NO3 + NO2-N) decreased during the incubation period, proving gaseous losses from the examined soils. Application of lower doses of nitrogen fertilizers could decrease nitrogen losses by denitrification as well as the occurrence of nitrite in toxic quantities in the investigated pseudogley soil.
AB  - Istraživanja su obavljena na zemljištu tipa pseudoglej iz okoline Šapca. Ispitivana zemljišta spadaju u grupu kiselih i jako kiselih zemljišta. Promene mineralnih oblika azota su praćene pomoću kratkotrajnih inkubacionih ogleda (vlažnost 30 % i temperatura 20 °S), sa i bez dodatka 100 i 300 ppm NH4-N. Tokom inkubacije utvrđene su povišene i toksične količine nitrita, koje su se u zemljišnom rastvoru zadržavale više dana i nedelja. Utvrđene količine nitrita su se javljale kao posledica usporene biološke nitrifikacije (kod manje kiselog zemljišta), dok su pri dodatku 100 i 300 ppm NH4-N one nastajale u procesu hemodenitrifikacije. U ispitivanim zemljištima se odvijala i spontana oksidacija nastalih nitrita hemijskim putem (hemijska nitrifikacija). Da bi se smanjili gubici azota procesom denitrifikacije i stvaranje toksičnih količina nitrita na pseudoglejnom zemljištu se može preporučiti primena nižih doza azotnih đubriva u odnosu na doze koje se primenjuju kod neutralnih i alkalnih zemljišta.

AB  - Nickel is a non-essential element in the nutrition of the majority of plant species and can be toxic to plants when its concentration in soils is high. Several soil properties have an effect on the uptake of this heavy metal by plants. The purpose of this investigation was to determine the effect of fertilization, soil acidification and liming on the uptake of Ni by maize plants grown on some alluvial soils. A pot experiment with maize plants grown on soils having various properties and elevated content of Ni was set up. The experiment lasted six weeks. The roots and shoots were analyzed for the concentration of Ni. From the results of the experiment, it can be concluded that the roots had higher concentrations of Ni than the shoots. The addition of mineral fertilizers (without application of other measures) mainly decreased the concentration and uptake of Ni by the roots and the transport of Ni to the shoots. Soil acidification (to pH 4.5) caused an increase in the Ni concentration in the plants and in its removal from the soil. Liming of acid soils had a positive effect on the uptake of Ni by young maize plants. The obtained results are important from the standpoint of reducing the pollution of plants by potentially toxic heavy metals.
AB  - Nikl nije neophodan element za ishranu većine biljnih vrsta i on može biti toksičan za biljke kada je njegova koncentracija u zemljištu visoka. Nekoliko osobina zemljišta ima uticaja na usvajanje ovog metala biljkama. Cilj ovog istraživanja je bio da se utvrdi uticaj đubrenja, zakiseljavanja zemljišta i kalcizacije na usvajanje Ni biljkama kukuruza gajenim na nekim aluvijalnim zemljištima. Postavljen je ogled u sudovima sa biljkama kukuruza koje su gajene na pomenutim zemljištima. Ogled je trajao 6 nedelja. Korenovi i nadzemni delovi su analizirani na sadržaj Ni. Može se zaključiti iz rezultata ogleda da korenovi imaju veće koncentracije Ni u odnosu na nadzemne delove. Dodavanje mineralnih đubriva (bez primene drugih mera) uglavnom je smanjilo koncentraciju i usvajanje Ni korenovima kao i njegov transport do nadzemnih delova. Zakiseljavanje zemljišta (do pH 4,5) povećalo je usvajanje Ni korenovima i njegov transport do nadzemnih delova biljaka. Kalcizacija kiselih zemljišta je imala pozitivan uticaj na usvajanje Ni mladim biljkama kukuruza. Dobijeni rezultati su značajni za smanjenje zagađivanja biljaka potencijalno toksičnim teškim metalima.

AB  - The purpose of this investigation was to determine the effect of long-term application of mineral and organic fertilizers (beef manure and cornstalks) on the content and distribution of iron in a calcareous chernozem soil. For this purpose soil samples were taken from an experimental field of the Maize Research Institute in Zemun Polje (Belgrade). Contents of total and available iron were determined by atomic absorption spectrophotometry after preparation of the samples for the analysis. Basic agrochemical properties were determined by applying standard methods of soil analysis. Variants where manure was applied alone or in combination with cornstalks have significantly higher content of total iron in relation to the control. Increase of total iron in these variants could be noticed till the depth of 80 cm. The investigated experimental variants have relatively low content of available Fe. Application of organic fertilizers caused increases in available iron content in relation to the unfertilized variant of the experiment. Results of correlation analysis indicate that none of the basic agrochemical properties has significant influence on the content of total iron. Statistically significant correlations were found between available iron on one hand and contents of humus and calcium carbonate on the other (r = 0,48 and r = -0,46, respectively). .

AB  - Cadmium is a nonessential element in plant nutrition that can be toxic to plants when its content in soils is high. Significant amounts of this metal can be introduced into soils through application of high doses of phosphorus fertilizers, farmyard manure and sewage sludge. Not much work has been done on the effect of different fertilization systems on the content of Cd in various soils in Serbia. The purpose of this investigation was to determine the effect of long-term application of mineral and organic fertilizers (beef manure and cornstalks) on the content of cadmium in a calcareous chernozem soil. For this purpose soil samples were taken from an experimental field of the Maize Research Institute in Belgrade. Total and available (DTPA-extractable) cadmium was determined by atomic absorption spectrophotometry. All experimental variants had lower content of total cadmium than soil samples taken before the experiment was set up. Comparison with the control indicated that the content of cadmium (total and available) increased under the influence of the applied fertilizers. It can be concluded that the investigated fertilization systems did not cause pollution of the calcareous chernozem soil with cadmium. Correlation coefficients between Cd content in the soil and some important agrochemical properties of the investigated samples are presented in this paper.

AB  - Some important chemical properties of various samples of two types of acid soil from Western Serbia (pseudogley and brown forest) are presented in this paper. Mobile Al was found in elevated and toxic quantities (10–30 mg/100 g) in the more acid samples of pseudogley soil. All samples of brown forest soil were very acid and the quantities of mobile Al were in the range from 12.8 to 90.0 mg/100 g. In a selected number of pseudogley soils, the influence of pH and other soil properties on the mineralization and nitrification processes was investigated. Strong inhibition of nitrification at low soil pH was found to be related to high quantities of mobile Al. At pH values less than 4.0 (in 1 M KCl), processes of chemical nitrification and denitrification of applied nitrites were registered in the pseudogley soils.
AB  - Istraživanja su obavljena na dva tipa zemljišta Zapadne Srbije (pseudoglej i smeđe šumsko zemljište). Oba ispitivana zemljišta karakteriše niska pH vrednost. Kod svih uzoraka smeđeg šumskog zemljišta utvrđene su toksične količine mobilnog Al za biljke i za mikroorganizme, a kod pseudoglejnog zemljišta toksične količine Al su utvrđene samo za neke uzorke. Na proces nitrifikacije, koji je praćen u odabranim uzorcima pseudogleja, direktno su delovali niska pH vrednost (kiselost) i visok sadržaj mobilnog aluminijuma. Dodavanjem NaNO2 utvrđeno je odvijanje procesa hemijske nitrifikacije i denitrfikacije u pseudoglejnom zemljištu pri pH manjem od 4,0 u 1M KCl.

AB  - Soil sampling was carried out in the Velika Morava river valley, covering the area from Velika Plana to the mouth of Morava to the Danube. The composite soil samples, representing alluvial soils (22 samples), cambisols (14) and smonitzas (4), were taken from plough layers, based on a regular square grid with intervals set at 5x5 km, covering total area of 100,000 ha. The total and available fluorine contents were determined in the soils samples. The highest average amount of total fluorine was found for alluvial soils (391 mg kg-1), then for smonitzas (348 mg kg-1) and the lowest one for cambisols (285 mg kg-1). These amounts are within normal fluorine content for soils (150-400 mg kg-1), although the maximum found levels were even about 500 mg kg-1. The available fluorine content was very low ( lt  1 mg kg-1), being mostly less than 0.2 % from its total amount, so it could be concluded that there was no danger from fluorine accumulation in the plants. Statistically significant correlation coefficient between total and available fluorine contents was not obtained. The total and available fluorine contents have mostly been in the correlation (with positive sign) with soil pH and the content of mechanical fraction silt+clay. Significant correlation coefficients between total fluorine content and the content of some heavy metals (Cr, Ni, Co, Cu, As) were also found, which indicated their mutual geochemical origin.

Za ukupni fluor najviše srednje vrednosti su nadjene u aluvijumima (391 ppm), zatim u smonicama (348 ppm) i najmanje u gajnjačama (285 ppm). Ove vrednosti se nalaze u granicama normalnih sadržaja za zemljišta (150-400 ppm), mada se maksimalne vrednosti kreću i oko 500 ppm. Pristupačni sadržaj fluora je u ispitivanim zemljištima jako nizak ( lt  1 ppm), što najčešće čini ispod 0,2 % od ukupnog fluora, pa se može zaključiti da ne postoji opasnost od akumulacije fluora u biljkama koje se gaje na ispitivanom području.

AB  - Phosphogypsum is formed as a by-product in the process of 'green' phosphoric acid production. This is done in the so called 'wet process' by the action of sulphuric acid on raw phosphate at low temperature ( lt 100 °C). Despite the same molecular formula and marked similarity with natural gypsum, phosphogypsum contains more than 50 impurities, and this is directly connected with the type of phosphate used in the production cycle. The aim of this paper was to consider the possibility of using phosphogypsum for amelioration of solonetz soil, bearing in mind its content of heavy metals, which are rather toxic for human organism and which can be transferred from soil to various plants used in human nutrition. On the other hand, there are very few data in the literature about the determination of heavy metals in phosphogypsum. The content of heavy metals in phosphogypsum was determined by atomic absorption spectrophotometry because this method has broad application in ana­lytical practice due to its high sensitivity, selectivity and precision. The results of the investigation indicate the following average content of heavy metals (in ppm): Fe-785, Pb-45, Zn-45, Cd-7, Mn-8, Co-10, Ni-20 and Cu-17. For the investigation of the effect of phosphogypsum on solonetz soil the following points were taken into consideration: maximum recommended dose of phosphogypsum (7 t/ha) for the amelioration of solonetz soil and the weight of soil layer (from 0 to 20 cm) having an area of 1 ha. The results obtained indicate that the amounts of heavy metals that are introduced into the soil with 7 t/ha of phosphogypsum are in the range from 0.035 to 0.8% of their maximum permissible content for arable soils. This means that only long-term application of phosphogypsum would introduce significant amounts of these elements into the soil.
AB  - Procesom dobijanja 'zelene' fosforne kiseline tzv. 'mokrim postupkom', dejstvom sumporne kiseline na sirovi fosfat na niskoj temperaturi ( lt 100 °C) kao nus-proizvod nastaje - fosfogips (sa faktorom 5:1, u odnosu na H3PO4). Uprkos istoj molekulskoj formuli i izraženoj sličnosti sa prirodnim gipsom, fosfogips sadrži preko 50 vrsta nečistoća, što je u direktnoj vezi sa vrstom fosfata koji je korišćen u proizvodnom ciklusu. Cilj rada bio je razmatranje mogućnosti primene fosfogipsa za melioraciju soloneca, sa aspekta sadržaja teških metala, koji su izuzetno toksični i kumulativni za čovekov organizam, a iz zemljišta prelaze u biljke, kojima se čovek hrani. Sa druge strane, u literaturi se nalaze veoma oskudni podaci o ispitivanju sadržaja teških metala u fosfogipsu. Sadržaj teških metala u fosfogipsu određivan je metodom atomske apsorpcione spektrofotometrije (AAS), budući da je to metoda koja je našla veliku primenu u praksi usled visoke osetljivosti, selektivnosti i preciznosti. Rezultati ispitivanja su pokazali sledeći sadržaj teških metala (u ppm): Fe-785, Pb-45, Zn-45, Cd-7, Mn-8, Co-10, Ni-20, Cu-17. Za ispitivanje uticaja primene fosfogipsa za melioraciju soloneca, uzeta je u obzir preporučena maksimalna norma za gipsovanje soloneca od 7 t/ha zemljišta i težina sloja debljine od 0 do 20 cm a površine 1 ha. Dobijeni rezultati su pokazali da se preporučenom maksimalnom normom za gipsovanje soloneca fosfogipsom unosi po 1 ha zemljišta od 0,035 do 0,8% od maksimalno dozvoljenog sadržaja teških metala - MDK vrednosti, što znači da bi tek višegodišnjom upotrebom fosfogipsa došlo do unošenja značajnijih količina ovih elemenata u zemljište. Kako se proces melioracije soloneca najčešće vrši u intervalu od 5 do 6 godina, unošenje teških metala bilo bi u zanemarljivoj količini i bez uticaja na životnu sredinu.

Kako se proces melioracije soloneca najčešće vrši u intervalu od 5 do 6 godina, unošenje teških metala bilo bi u zanemarljivoj količini i bez uticaja na životnu sredinu.",

AB  - Beer-based drinks, 'Radler' type products in particular, arouse interest for a number of reasons. These newly produced drinks were obtained by mixing beer and soft drinks and are intended for a larger number of target groups than their each single component. Also, they combine advantages of both components in physiological respect. They have lower alcohol content than beer, are more palatable and refreshing, can be consumed in larger amounts, retaining beneficial and physiological value of beer. As NATO air strikes resulted in heavy environmental contamination, the question is raised about the safety of these drinks and the level of toxic elements in them as well about the level of micro- and macro-elements having beneficial effects on the body. The paper gives the analysis results for 35 samples of different 'Radler' Beer-based products manufactured by domestic producers. The level of elements belonging to three distinct groups of heavy metals and that of the most important micro- and macro-elements, of therapeutic and physiological value for the body, were determined. The obtained values were compares with available data on similar products in the world, with values obtained for domestic products in the period preceding environmental contamination, and, in the case of biologically important elements, with their contents in one of oligomineral-vitamin products.
AB  - Pića na bazi piva, a pogotovo proizvodi tipa 'Radler' interesantni su sa vise aspekata. Predstavljaju jedan nov proizvod dobijen kombinacijom piva i gaziranih bezalkoholnih pica namenjen većem broju ciljnih grupa od pojedinačnih komponenata od kojih su proizvedeni, a ujedno sa fiziološkog aspekta objedinjuju prednosti svakog od njih. Sadrže niži sadržaj alkohola od piva, pitkija su i vise osvežavaju, mogu se piti u većim količinama, a istovremeno u određenoj meri zadržavaju blagotvorna i fiziološki vrlo povoljna svojstva piva. Upravo iz tog razloga postavlja se pitanje njihove zdravstvene ispravnosti i prisustva pojedinih toksičnih elemenata kao posledica ekološkog zagađenja uzrokovanog vazdušnim dejstvima NATO alijanse, odnosno mikro- i makro elemenata čiji sadržaj ima povoljno delovanje na organizam. U radu su prikazani rezultati analize 35 uzoraka različitih 'Radler' proizvoda dobijenih na bazi piva različitih domaćih proizvođača. Određen je sadržaj elemenata koji spadaju u tri karakteristične grupe teških metala kao i najznačajnijih mikro- i makroelemenata koji imaju terapeutski i fiziološki značaj za organizam. Rezultati analize 35 uzoraka proizvoda tipa 'Radler' proizvedenih nakon završetka ratnih dejstava, pokazuju da u pogledu ni jednog toksičnog elementa nije došlo do porasta sadržaja i da su nađene vrednosti u granicama, ili čak ispod vrednosti karakterističnih za proizvode ove vrste na domaćem tržištu. Vrednosti su znatno ispod zakonski regulisanih maksimuma i u granicama koje se sreću i u srodnim proizvodima u svetu. Sa druge strane, interesantni su podaci koji se odnose na prisustvo biogenih elemenata koji su uzrok povoljnog delovanja piva na organizam. Njihov sadržaj u proizvodima tipa 'Radler' je niži u odnosu na pivo i ovi proizvodi se ne mogu tretirati kao njihov izvor. Međutim, poređenje sa oligomineralnim vitaminskim preparatom 'Oligovitom' (ICN) ukazuje na neke interesantne činjenice. Unošenjem 1 l ovih proizvoda unosi se 10% Mg, 10-60% Mn, 30% Cu, 50% Zn i 50% Co koja se inače unosi pilulom 'Oligovita' kao preporučena dnevna dopuna svakodnevne ishrane dece i odraslih.

AB  - A number of common edible fungi were analyzed for their contents of Pb, Fe, Cr, Ni, Co, Zn, Cu, Mn and As in order to estimate pollution of the environment. The results indicate that the Fe level in analyzed species can be as high as several hundreds mg/kg weight. The Ni level in Leccinum scabrum was found to be up to 18 mg/kg. Levels of As were at or below 0.90 mg/kg in all species. Cu levels were fairly similar in different species. The results of several surveys show that there can be large differences in the concentrations of the same element (e.g. Mn) in the same species. Mn level was found to be very high in the species Boletus edulis, as has been shown by others. In the other analyzed species level of Mn was low. All samples except one 6. edulis had levels of Pb lower than it is regu­lated by the law.

Rezultati su pokazali da sadržaj Fe u analiziranim uzorcima može dostići nekoliko stotina mg/kg suve materije gljiva. Sadržaj Mi je dostigao 18 mg/kg. Sadržaj As je bio ispod 0,9 mg/kg u svim uzorcima, a sadržaj Ću je manje varirao kod svih uzoraka. Podaci pokazuju da može doći do velike razlike u sadržaju teških metala (Mn) kod iste vrste sa različitih lokaliteta što se vidi u slučaju vrste Boletus edulis. Kod ostalih vrsta sadržaj Mn je bio relativno nizak. Svi ispitivani uzorci gljiva osim jednog uzorka B. edulis su imali nizak sadržaj toksičnog olova.

AB  - The purpose of this paper was to determine the effect of long-term application of mineral and organic fertilizers (beef manure and cornstalks) on some important agrochemical properties of a calcareous chernozem soil. For this purpose soil samples were taken from an experimental field of the Maize Research Institute in Belgrade. There were six variants in the experiment and one of them was the control, i.e. variant without application of mineral and organic fertilizers. Basic agrochemical properties of the investigated soil samples were determined by standard methods of soil chemical analysis. Application of fertilizers did not cause statistically significant changes in soil pH, calcium carbonate content and C/N ratio. However, the content of humus and total nitrogen increased significantly in all variants where organic fertilizers had been applied. Contents of available phosphorus and potassium increased in all fertilized variants.

U tu svrhu uzeti su uzorci zemljišta sa jednog poljskog ogleda Instituta za kukuruz u Zemun Polju. Inače, ogled je postavljen 1971. godine sa kukuruzom u monokulturi. U ogledu je bilo 5 đubrenih varijanti i jedna neđubrena varijanta (kontrola). Agrohemijska svojstva prikupljenih uzoraka su određena primenom standardnih metoda za ispitivanje zemljišta. Na osnovu dobijenih rezultata može se zaključiti sledeće. Nisu utvrđene statistički značajne razlike između đubrenih varijanti ogleda i kontrole u pogledu vrednosti za pH (u vodi i 1M KCl), sadržaj kalcijum-karbonata i C/N odnos. Međutim, što se tiče ostalih agrohemijskih osobina zemljišta tu je situacija dosta drugačija. Značajno povećanje sadržaja humusa i ukupnog azota je utvrđeno kod svih varijanti gde su primenjena organska đubriva. Slična je situacija i sa sadržajem pristupačnog fosfora i kalijuma u zemljištu, s tim što je sadržaj pristupačnog fosfora značajno povećan i kod varijante gde su primenjena samo mineralna đubriva. Utvrđene su statistički značajne razlike između dva sloja zemljišta u pogledu sadržaja pristupačnog fosfora i kalijuma.

AB  - The purpose of this investigation was to determine the effect of long-term application of mineral and organic fertilizers (farmyard manure and cornstalks) on the content of zinc and lead in a calcareous chernozem soil. For this purpose soil samples were taken from an experimental field of the Maize Research Institute in Belgrade. Total and available (DTPA-extractable) zinc and lead were determined by atomic absorption spectrophotometry, after necessary preparations of soil samples for the analysis. Total zinc content did not change significantly under the influence of applied fertilizers. However, the content of available zinc increased significantly in the experimental variants where organic fertilizers had been applied. It was found that fertilization did not have significant effect on the content of total and DTPA-extractable lead.

Sadržaj ukupnog cinka se nije značajno promenio pod uticajem primenjenih đubriva. Međutim, sadržaj pristupačnog cinka se značajno povećao u svim varijantama ogleda gde je primenjeno stajsko đubrivo. Inače, ovo povećanje pristupačnog cinka se uočava do dubine od 80 cm. Utvrđeno je da višegodišnja primena đubriva nije imala značajnog uticaja na sadržaj ukupnog i pristupačnog olova.

abstract = "The purpose of this investigation was to determine the effect of long-term application of mineral and organic fertilizers (farmyard manure and cornstalks) on the content of zinc and lead in a calcareous chernozem soil. For this purpose soil samples were taken from an experimental field of the Maize Research Institute in Belgrade. Total and available (DTPA-extractable) zinc and lead were determined by atomic absorption spectrophotometry, after necessary preparations of soil samples for the analysis. Total zinc content did not change significantly under the influence of applied fertilizers. However, the content of available zinc increased significantly in the experimental variants where organic fertilizers had been applied. It was found that fertilization did not have significant effect on the content of total and DTPA-extractable lead., Cilj ovoga rada je bio utvrđivanje uticaja višegodišnje primene mineralnih i organskih đubriva (stajnjak i kukuruzovina) na sadržaj cinka i olova u karbonatnom černozemu. U tu svrhu uzeti su uzorci zemljišta sa jednog poljskog ogleda Instituta za kukuruz u Zemun Polju.

AB  - The need for expanding assortment of beer and gaining new markets gave rise to some new products: drinks based on beer. One of such products is 'Radier' - a mixture of beer and soft drink in ratio 1:1. Thanks to their sensory characteristics and low alcohol content such beverages can be consumed in large amounts. This raises the question of their physiological value. The content of Fe, Co, Zn, Ni, Pb, Cd, Cr, Mn, Cu and K was determined in a large number of beer samples taken from the market and samples of soft drinks produced in the laboratory from flavors obtained from various producers. Besides these elements, As, Hg and pesticides were determined in the beer samples. Atomic absorption spectrophotometry and gas chromatography were used for the aforementioned determinations. The results obtained indicate that the content of harmful components in all analyzed samples is within satisfactory limits, below or far below permissible levels, so that these types of product can be safely consumed in relatively high amounts. Alcohol is present in such concentration and form, which enables its resumption and elimination from organism, and is not a limiting constituent as it is in a standard beer. .
AB  - Poslednjih godina na tržištu se pojavljuje sve više proizvoda dobijenih mešanjem standardnog piva i nekog drugog osvežavajućeg bezalkoholnog, ili alkoholnog napitka. Razloga za to ima više. Sa jedne strane to je potreba da se proširi asortiman proizvoda, a sa druge da se osvoje novi potrošači i poveća potrošnja piva. Najzastupljeniji proizvodi ove vrste su proizvodi tipa 'Radler' mešavine piva i gaziranog osvežavajućeg pića u odnosu 1:1. Reč je o piću koje je zamišljeno kao osvežavajući napitak koji treba da utoli žedj i koji se može piti u relativno velikim količinama. Postavlja se pitanje u kojoj meri je to fiziološki ispravno sa aspekta njegovog kemijskog sastava i prisustva štetnih komponenata. U radu ispitivan je sadržaj: Fe. Co, Zn, Ni. Pb. Cd. Cr. Mn i Ću i K u 15 uzoraka piva uzetih sa tržišta i uzoraka bezalkoholnih osvežavajućih pića proizvedenih u laboratoriji na bazi aroma različitih proizvođača metodom atomske apsorpcione spektrofotometrije i sadržaj As, Hg i pesticida u pivu metodom gasne hromatografije. Rezultati ukazuju na to da je sadržaj štetnih sastojaka u svim ispitivanim uzorcima u zadovoljavajućim granicama, ispod ili znatno ispod zakonom predviđenog maksimuma, a sadržaj fiziološki važnih elemenata takav da se proizvodi ove vrste mogu konzumirati u relativno velikim količinama, bez opasnosti od eventualnih štetnih posledica, pri čemu se u organizam unosi jedan broj fiziološki vrednih elemenata. Konstatovano je da je sadržaj Zn u domaćim pivima u prošeku oko 6 puta viši. sadržaj Fe viši za oko 5 puta, a sadržaj Mn nešto viši u odnosu na odgovarajuće proizvode u svetu. To međutim, ne umanjuje vrednost piva, budući da je reč o elementima, koncentracijama i obliku u kome se nalaze koji upravo imaju povoljno delovanje na organizam. Sa druge strane, sadržaj K je u domaćim pivima znatno niži u odnosu na odgovarajuće proizvode u svetu. Sve ove činjenice odražavaju se i na sastav proizvoda dobijenih na bazi piva. Njihovim konzumiranjem unosi se manje fiziološki značajnih elemenata u odnosu na pivo, ali u svakom slučaju znatno više u odnosu na standardne gazirane bezalkoholne napitke. Pri tome je od značaja daje alkohol prisutan u količini i obliku koji omogućava njegovu resorpciju i eliminaciju iz organizma i više ne predstavlja limitirajući faktor, kao u slučaju standardnog piva.
