AB  - This study aims at analysing physical, chemical and microbiological properties, and content of macro- and microelements in the water from the Požarevac city public water supply system. Analysis shows an increased content of Ca in drinking water, as a result of the position of Požarevac on the sediments of river terrace of accumulative character of t1 type, predominantly consisting of quartzite. The water from the public water supply is alkaline ('calcic', 'bicarbonate water') and very hard, due to the increased Ca content. Beside Ca, potassium and aluminium exceed the maximum contaminant level, while Pb and Cd are at the very limit. Calculated data show that there are no short-term health risks regarding elements exceeding allowed concentrations found in the public water supply system. Data analysis regarding long-term health risks shows that Cd present in drinking water poses the only relevant threat to human health. Cancer risk is present in 202 out of 1000 inhabitants using this water.

AB  - In order to verify the content of macro- and microelements in drinking water in the village of Dubravica in the Branicevo district, which has no centralized water supply system, an analysis of the water sampled from two individual wells was conducted using the indirect method recommended by Rajkovic and associates. Tests on the RDA and AAS showed that: Al, Fe, Cr, Pb and U were in concentrations higher than the values allowed by Regulations on the hygienic quality of drinking water. To determine the risk of the presence of toxic metals in the elevated concentrations, the assessment of short-term and long-term potential carcinogenic risks was conducted. Based on the results obtained in the tested water samples, it is noticed that the value of the coefficient of risk (CR) was less than 1 for all potentially toxic metals that were determined in drinking water, which implies that there is no short-term carcinogenic potential risk to human health. Based on the results of the long-term potential risk for the occurrence and development of cancer, the risk of getting cancer of Cr was identified in the inhabitants of the village that used potable water of the first sample. In case of Pb, a risk of developing cancer, concerning the first sample of drinking water, may occur in 44 out of 1000 people and regarding the second sample, in 183 out of 1000 people. Based on the calculated estimates of the long-term health risk related to the presence of U in drinking water, it can be seen that there is a health risk related to the use of both water samples. On the basis of the calculated estimates of the long-term health risk related to the presence of uranium in drinking water, it can be noticed that the use of both water samples may lead to the potential risk of developing cancer: in 24.5 inhabitants regarding the first water sample and in 10.3 out of 1000 inhabitants in the case of the second water sample.

AB  - The water quality of drinking water: physico-chemical and microbiological safety of the individual wells from the Dubravica village was investigated with the methods recommended by Regulations of hygienic quality of drinking water. The method of indirect determinations was used for testing the content of heavy metals in drinking water based on the scale sedimented on the house water heater. The scale was exanimated with scanning electron microscopy (SEM), X-ray diffraction analysis (XRD) and the method of thermogravimetric (TG) and differential thermal analysis (DTA). Physico-chemical and microbiological examinations have shown that the drinking water from individual wells are completely safe for use. The results of heavy metals contents showed that the indirect method is more precise and more reliable because it can detect the concentration of heavy metals (in the examined samples of Cd and Pb) that are below the threshold of detection by classical methods of water analysis. This is very important because, in this way, the use of heavy metals is monitored in long period of time and it can prevent potential effects on human health. The uranium content is below the allowed value prescribed by law, but the method of fractional extraction points to its anthropogenic origin.

AB  - In rural areas in the territory of Pozarevac samples were taken in 10 villages that have no central water supply: Ostrovo, Petka, Kličevac, Maljurevac, Bubušinac, Bratinac, Dubravica, Batovac, Brežane, Živica. 20 samples of water have been taken from the individual wells in households in different parts of the each village. Sampling, testing methods and interpretation of results were done in accordance with the Regulation on the hygiene of drinking water includes the following parameters: smell, color, pH, consumption of KMnO4, turbidity, nitrite, nitrate, ammonia, chloride, conductivity and microbiological correctness and determination of heavy metals in the drinking water by atomic absorption spectrophotometry. The results of water analysis differ from village to village. In most communities the water is mostly hygienically improper. The research has shown that the % of microbiological safety in the tested water samples ranges from 85% (the village of Dubravica) to completely unsafe water, sampled in the village of Bare. Physical and chemical quality of drinking water ranged from 95% (the village of Dubravica), to completely unsafe water , sampled (villages Petka, Lučica and Prugovo). The most common cause of this are the elevated values of the following chemical substances: nitrate, nitrite, the turbidity of the suspended inorganic materials, the color of water as a result of the presence of colloidal dissolved substances of plant origin, the concentration of Clions, the presence of organic matter in drinking water, elevated conductivity and the pH value of the water. In the analyzed samples of drinking water in rural households ammonia concentration is within acceptable limits, while the heavy metal content in all samples of drinking water is below the maximum allowable concentration, and in some cases even below the detection limit. Uranium content in the tested water samples showed that the concentration of uranium is within the limits of natural values.
AB  - U seoskim naseljima na teritoriji grada Požarevca uzeti su uzorci vode za piće iz 10 seoskih naselja: Ostrovo, Petka, Kličevac, Maljurevac, Bubušinac, Bratinac, Dubravica, Batovac, Brežane, Živica. U svakom naselju uzeto je po 20 uzoraka vode iz individualnih bunara u domaćinstvima u različitim delovima sela. U skladu sa Pravilnikom o higijenskoj ispravnosti vode za piće radila se analiza vode za piće koja je obuhvatila: miris, boju, pH vrednost, utrošak KMnO4, mutnoću, nitrite, nitrate, amonijak, hloride, elektroprovodljivost, mikrobiološku ispravnost i sadržaj teških metala. Dobijeni rezultati analiza pokazali su da je u većini naselja voda za piće je u velikom procentu higijenski neispravna. Ispitivanja su pokazala da se % mikrobiološke ispravnosti u ispitivanim uzorcima vode kreće od 85% (selo Dubravica) do potpuno neispravne vode za piće. Fizičkohemijska ispravnost vode za piće kretala se od 95% (selo Dubravica) do potpuno neispravne vode za piće (sela Petka, Lučica i Prugovo). Najčešći uzrok neispravnosti vode za piće su povišene vrednosti: nitrata, nitrita, zatim mutnoća od suspendovanih materija neorganskog porekla, boja vode kao posledica prisustva koloidno rastvorenih materija biljnog porekla, koncentracija Cl-jona, prisustvo organskih materija u vodi za piće, povišene vrednosti elektroprovodljivosti i pH vrednost vode. U analiziranim uzorcima vode za piće u seoskim domaćinstvima koncentracija amonijaka je u dozvoljenim granicama, dok je sadržaj teških metala ispod maksimalno dozvoljene koncentracije, a u nekim slučajevima čak i ispod granice detekcije. Sadržaj urana u ispitivanim uzorcima vode pokazuju da je koncentracija urana u granicama prirodnih vrednosti.

AB  - Preparation of samples by microwave technique consists of large number of phases, from taking samples till receiving homogeneous solution for instrumental analysis. Samples preparation can include combination of drying, wetting, extraction, digestion, analytic separation and solvent removing. The analysis of content of heavy metals in potato from Braničevo Region by the usage of atomic absorption spectrophotometry (AAS) showed that certain samples of potato contain more than 1ppm of lead, and that certain samples contain amount of lead which is even 4 times higher than allowed MDK value. As for cadmium, all samples contains amount which is 7 to even 20 times higher than allowed MDK value. Chrome and nickel are not allowed by Law to be in products for human diet, and by this analysis it is determined that these samples contain chrome (total). In none of these samples was determined the presence of nickel. Received results of the analysis showed that large amounts of chemical (mineral) fertilizers were used at these soils. According to received results it can be concluded that the soil as well as increased usage of phosphate fertilizers are main cause for the presence of heavy metals in potato
