Determination of arsenic concentrations in hair samples with ICP-MS in area of Eastern Croatia.

The eastern Croatia together with Central Hungary, Serbia and Western Romania (Danube Basin) belongs to the Pannonian Basin where higher groundwater As concentrations have been reported. A recent study of As concentrations in soil shows highest As concentrations in some areas of eastern Croatia. Long term exposure to arsenic may be assessed by analysing the content in hair. Arsenite (As III) reacts readily with sulfhydryl group (-SH) in a variety essential enzymes and proteins. The hair samples were taken in areas: Vladislavci, Čepin, Osijek, Dalj, Vukovar, Vinkovci and Slavonski Brod. Depending the investigated area, the mean concentrations ranged from 0, 018 (Vinkovci) to 32 µg g-1 (Vladislavci) whereby these last value, significantly exceeded the upper range of reference value (0, 32 µg g-1) . The arsenic concentrations from Našice, Osijek, Slavonski Brod, Vukovar and Vinkovci area were within or slightly above allowed reference range. Maximum As concentrations in hair samples were detected in the Vladislavci (647, 60 µg g-1) and Čepin (526, 78 µg g-1) areas.
