AB  - An indirect method of metal content determination in drinking water based on a study of scale, showed precision, reliability and reproducibility of the obtained results. Results showed that the water quality, based on the metal content in the water, is quite constant and metals are in a concentration allowed by the Regulations. An increase of Uranium in drinking water (mainly the isotope 238U) was determined and its anthropogenic origin is proven based on the results of fractional extraction. Based on the content of macro- and microelements it is determined type of tested water as HCO3- Ca-Mg. In the examined period the concentration of macro- and microelements was below the MAC (Maximum Allowable Concentration) values. Ratio of Ca/Mg according to the Regulations should be between 3 and 4, while in the period of examination was varied in the range of 10.67 to 16.76, which means that the content of Mg in water is very low. Regarding to the period of 2011-2015 the input of heavy metals via drinking water was significantly increased (even 10 times) in comparison to the period of 2008-2011. As result of increased concentrations of Fe and Zn is a high growth of heavy metals. Calculated data showed that the risk of input microelements: Al, Fe and Pb, which are in studied water much higher than allowed by the Regulations, is not having any short-term risk to human health. Data analysis of the risk on the long-term health showed that the only real danger is the presence of Pb in drinking water. The risk of cancer is present in 23-58 population of 1000 people who are using this water for drinking.
AB  - Indirektna metoda određivanja sadržaja metala u vodi za piće bazirana na ispitivanju kamenca pokazala je preciznost, pouzdanost i reproduktivnost dobijenih rezultata. Rezultati ispitivanja potvrdili su da je kvalitet vode, baziran na sadržaju metala u vodi, konstantan i da se metali nalaze u koncentraciji koja je dozvoljena pravilnikom. Utvrđen je porast urana u vodi za piće (uglavnom izotopa 238U), a na osnovu rezultata frakcione ekstrakcije dokazano je njegovo antropogeno poreklo. Na osnovu sadržaja makro- i mikroelemenata utvrđeno je da je ispitivani tip vode HCO3-Ca-Mg. U ispitivanom periodu koncentracija makro- i mikroelemenata bila je ispod MDK (Maksimalno dozvoljena koncentracija) vrednosti. Odnos Ca/Mg po pravilniku treba da iznosi između 3 i 4, dok je u ovom periodu varirao u opsegu 10,67-16,76, što znači da je sadržaj Mg u vodi jako nizak. Unos teških metala preko vode za piće u periodu od 2011-2015. godine značajno je povećan (čak 10 puta) u odnosu na period od 2008-2011. godine. Ovako visok porast teških metala posledica je povećane koncentracije Fe i Zn. Proračunati podaci ukazuju da rizik od unošenja mikroelemenata: Al, Fe i Pb, koji se u ispitivanim vodama nalaze u vrednosti višoj od one dozvoljene pravilnikom, ni za jedan metal ne pokazuju kratkoročni zdravstveni rizik po zdravlje ljudi. Analiza podataka o dugoročnom zdravstvenom riziku ukazuje da jedina realna opasnost postoji od prisustva Pb u vodi za piće. Rizik od pojave kancera prisutan je kod 23-58 stanovnika od 1000 stanovnika koji koriste ovu vodu za piće.

AB  - The study of spatial distribution of activity concentration of U-238, Ra-226, (210)pb, Th-232, K-40 and Cs-237 radionuclides in the surface soil samples (n = 42) collected in the vicinity of four coal-fired power plants in Serbia is presented. Radioactivity measurements in soils performed by gamma-ray spectrometry showed values [Bqkg(-1)] in the range: 15-117 for U-238, 21-115 for Ra-226, 33-65 for (210)pb, 20-69 for Th-232, 324-736 for K-40, and 2-59 for Cs-137. Surface soil radioactivity that could have resulted from deposition of radionuclides from airborne discharges or resuspension of ash from disposal sites showed no enhanced levels. It was found that variation of soil textural properties, pH values, and carbonate content influenced activity levels of natural radionuclides while radiocesium activities were associated with soil organic matter content. Modification of some soil properties was observed in the immediate vicinity ( lt 1 km) of power plants where the soil was more alkaline with coarser particles (0.2-0.05 mm) and carbonates accumulated. Calculated average values of the absorbed gamma dose rate and annual external effective dose originating from the terrestrial radionudides were 69.4 nGy/h and 0.085 mSv, respectively.

AB  - In this paper the content of metal in drinking water was determined in two samples, one from 2008 and other from 2010, by the indirect method based on the analysis of scale, which had originally been suggested by Rajkovic and associates. Received results confirmed that drinking water according to the metal content was of constant level (metals are lower than MAC values), but with increased content of U. By the method of fraction extraction it was proved that increased content of U regarded mainly to natural U, and less to U of anthropogenic origin. The increased content of isotope 90Sr was also noticed, probably as the effect of increased presence of alkaline earth metals. The analysis structure of scale by the usage of SEM determined that the dominant form was calcium carbonate of crystal structure of hexagonal shape which corresponded to calcite. By Röentgen diffraction analysis of dust it was determined the content of calcite which contained CaO; MgO; FeO; MnO and CO2 and it belongs to medium manganese calcites. All the analyses done in this paper, confirmed that indirect method of determination of metal content had been reliable and applicable for determination of low concentrations of metals in drinking water
