Soil burden by persistent organochlorine compounds in the vicinity of a coal-fired power plant in Croatia: A comparison study with an urban- industrialized area
The impact of a coal-fired Plomin Power Plant (PPP) in Croatia on PCB soil burden was examined by comparing the occurrence, levels and dominant PCB congeners in soil from the PPP with the values determined in urban-industrialized soil (Varaždin, Croatia). Soil contamination level with organochlorine pesticides (OCPs) at both locations are also provided. Topsoil samples were collected at five distances (100800 m) along a downwind pollution gradient from the PPP and across the city. The total content of PCBs in 100-m soil was nearly 20-fold the levels found in 800-m soil pointing to the PPP as a local source of soil contamination. The PPP soils were dominated by indicator congeners, particularly hexa-PCBs. A different profile and mass fraction range of PCBs in soils from PPP and Varaždin area indicated the different source of contaminants. Levels of ΣiPCB in PPP soils (0.2519.07 g kg- 1) were higher than PCB levels determined in soils from Varaždin (0.295.52 g kg-1), partially as a result of higher OC content in PPP soils. PPP soil burden with PCBs corresponded to a lower end of PCB level ranges reported for cities with high population and heavy industry. OCPs were detected at significantly higher levels in Varaždin soils than in PPP soils with the highest contribution of DDT- like compounds (DDX) at city area with the highest impact of river deposits. Levels of DDX in Varaždin soils indicated a fresh atmospheric input of p, p'-DDT. In PPP soils were detected only p, p’-DDE and HCB at levels corresponded to their global environmental presence.
