Sažetak
The only coal-fi red power plant in Croatia is situated near the city of Labin, on the east coast of the Istrian Peninsula (the Northern Adriatic Region). The Raša coal (with super-high content of sulphur, up to 14%) was mined at six localities around the city of Labin for more than a century. Our latest research showed that the soil surrounding the plant is highly polluted with PAHs, and moderately polluted with potentially toxic trace elements Cd and Se. Herewith, the aim of this study was to assess for the fi rst time a health risk for the local inhabitants from Cd and Se caused by ingestion or dermal exposure to soil particles. The hazard index (HI) was used to assess non-carcinogenic human health risk of Cd and Se. Since slope factors for Cd and Se based on oral or dermal exposure of general population are not assigned due to the lack of evidence of carcinogenicity, we were not able to calculate carcinogenic risk from Cd and Se present in soil. The results showed that the calculated non-carcinogenic risk due to Cd (HImax=0.06) and Se (HImax=0.02) in soil were well below the threshold value (HI=1) for both adults and children, indicating that exposed individuals are unlikely to experience adverse health effects. However, further detailed investigation including larger number of potentially toxic and carcinogenic trace elements will be conducted in the future. These results will provide basic information of metal pollution control and environment management in the Labin area.
