In order to evaluate the genotoxicity of airborne particulate matter extracted with dichloromethane (APE), the rat microsome mediated (S-9) or DNA repair enzyme treated Comet assays were performed using the single cell gel electrophoresis in A549 human lung carcinoma cells. It was found that the cells interacting with APE showed more DNA single-strand breaks relative to untreated cells. The genotoxicity of APE was increased with the treatment of S-9 mixture. Microsome mediated DNA damage was inhibited by CYP1Al inhibitor, quercetin. The APE also showed oxidative DNA damage evaluated by endonuclease III treatment. Oxidative DNA damage of APE was inhibited by antioxidants such as vita- min C and Trolox. We also found that the vegetables or fruits extract may reduce APE-induced genotoxicity by their anti- oxidant activity and CYP1A1 inhibition
