Određivanje koncentracija arsena u uzorcima urina i seruma stanovnika istočne Hrvatske metodom ICP‐MS

affects millions of people in different parts of the world. The groundwater in eastern Croatia has been found to contain very high concentrations of arsenic. Several studies conducted in previous decade have indicated that almost 200, 000 people are daily drinking water with arsenic concentrations ranging from 10‐610 μg L–1. A systematic research of the arsenic concentrations in urine and serum of eastern Croatia populations was never made. Some published papers covered certain segments (water, soil, food, or biological specimens) of a limited geographical area and on a smaller number of samples. The aim of the present study was to evaluate variations in human exposure to arsenic in eastern Croatia based on arsenic concentrations in water, urine and serum samples collected from 505 inhabitants living in eastern Croatia. In this study we selected 391 inhabitants from areas with elevated concentrations in drinking water (Osijek, Našice, Čepin, Vladislavci, Dalj) as well as control population (114) exposed to concentrations of arsenic in drinking water that were below the EU maximum admissible level of 10 μg L–1 (Vinkovci, Vukovar, Slavonski Brod). The arsenic concentrations differed significantly (Mann‐ Whitney test) in the samples of urine and serum (p=0.036886 ; p=0.036889) taken from two investigated areas. In urine samples from areas with elevated arsenic concentrations in drinking water, median values were from 19.40 to 73.40 μg L–1. Median values for arsenic in urine and serum samples in Vinkovci, Vukovar and Slavonski Brod area were well below reference values (urine: from 3.8 to 8.5 μg L– 1 ; serum from 0.55‐0.62 μg L–1).
