Toxicity risk assessment of sulfur and PAHs in soil surrounding a coal-fired power plant

The main objectives of this study were: (1) to investigate the spatial (site specific) distribution of sulfur, PAHs, and trace elements in topsoil around the Plomin coal-fired power plant (CFPP) taking into account direction of the prevailing winds in the area ; and (2) to assess cytotoxic and genotoxic potential of water extracts of this soil. The mean sulfur content of soil samples taken from the south-western quadrant is approximately 12.5 times greater compared to the control sites. This is mainly due to the sulfur content in the samples situated nearest to the CFPP (100-400 m), along the pollution gradient line. The total concentrations of PAHs in topsoils around the Plomin CFPP varied from 31 ng/g in the control samples collected outside the 10-km zone, to 13, 535 ng/g at a distance of 100 m from the CFPP. This study demonstrated that the CCO cell line proved to be suitable for the purpose of the investigation of the potential cytotoxic and genotoxic effects of contaminated soils from the Plomin CFPP. The obtained cytotoxic effects of water soil leachates on the CCO cells indicated that these effects could be related to the increased level of sulfur as well as PAHs.
