RESUMO
Ground waters in the region of Autonomous Province of Vojvodina, Republic of Serbia are endangered by arsenic (up to 0.750 mg/l). Total arsenic concentration was determined In samples of untreated and treated water from some local and central water-supply systems. Results are compared to actual regulations in the country. This analysis encompassed 324 drinking water samples of various sources, analyzed in the Institute of Public Health Novi Sad, during 2005. Determined concentration of total arsenic in drinking water varies from 0.005 to 0.450 mg/l. Arsenic concentration in the river Danube water was within recommended value for I-II class. Maximum arsenic daily intake through food and nutrition was 60.9 +/- 22.3 microg/day in 2000. To understand importance of the problem of arsenic environment contamination in Vojvodina region, our own results, as well as the results of other authors are presented and analyzed (drinking water: 173 samples, moss deposition and daily intake through nutrition).
