Determination of arsenic in hair samples using ICP-MS in different areas of Slavonia

Problem of elevated arsenic concentrations in environment of east Croatia has been investigated for the past 15 years in Croatia , and still raises increased public attention. The eastern Croatia together with Central Hungary, Serbia and Western Romania belongs to the Pannonian Basin where higher As concentrations are existing, mainly as a geochemical property of the groundwater. Arsenic has acute toxic effects and chronic such are “black foot disease”, cardiovascular and carcinogenic effects. It is especially toxic for uropoetic system. Hair samples are very usefull for determination of long term exposure. Aim of the study: was to investigate long term exposure to arsenic by analysing the arsenic content in hair. Methods: The hair samples from 507 adult examinees residing permanently were taken in following areas: Vladislavci, Čepin, Osijek, Dalj, Vukovar, Vinkovci and Slavonski Brod and analysed using ICP –MS method. Results: 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, 31 µg g-1) . The arsenic concentrations from Našice, Osijek, Slavonski Brod, Vukovar and Vinkovci area were within or slightly above maximum 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. Conclusion: Concentrations of arsenic in water samples do not suggest potential danger of acute intoxication ; however, long-term effects on the health of the population should not be excluded. Further extended research should be done.
