Summary: | 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. [Project of the Serbian
