The genotoxic acitivity of complex mixtures of organic extracts from urban air particles (PM2.5) collected in various localities of the Czech Republic with different levels of air pollution was compared. As markers of genotoxic potential, DNA adduct levels and oxidative DNA damage (8-oxodG levels) induced by EOMs in an acellular assay of calf thymus DNA coupled with 32P-postlabeling (DNA adducts) and ELISA (8-oxodG) were employed. The results indicate that the industrial emissions prevailing in Ostrava-Bartovice represent a substantially higher genotoxic risk that mostly traffic-related emissions in Ostrava-Poruba. B[a]P and c-PAH contents in EOMs are the most important factors relating to their genotoxic potential.
