The genotoxicity of the organic extracts (EOMs) from three size fractions of aerosols (ranging from 0.17 to 10µm and collected in 4 localities differing in the extent of pollution) was compared using the analysis of total DNA adducts induced in an acellular assay with/without metabolic activation. It was found that most of the observed genotoxicity was connected with a fine particulate matter fraction (<1µm). These fine fractions bound the highest amount of c-PAHs in all aerosol sites, which might be related to their higher specific surface. As for aerosol mass, both fine and condensational fractions are effective carriers of c-PAHs. Similarly, the DNA adduct levels per m3 of air were highest for the fine fraction and a strong correlation was found between the c-PAHs and DNA adduct levels induced by EOMs in all the localities and for various size fractions.
