PM2.5 at an urban site influenced by natural sources, road traffic, steelmaking and petrochemical industries. Organic extract of PM2.5-0.3 and PM2.5 revealed mutagenic effects on Ames TA98 and YG1041 strain. Different responses for cytotoxicity and proliferation assays for native PM, organic extract or water-soluble fraction. Key-role of the ultrafine fraction in the mutagenicity and cytotoxicity of PM2.5.
