Chlorinated polycyclic aromatic hydrocarbons (ClPAHs) have been reported to occur in urban air. Nevertheless, sources of ClPAHs in urban air have not been studied, due to the lack of appropriate analytical methods and standards. In this study, we measured concentrations of 20 ClPAHs and 11 brominated PAHs (BrPAHs) in fly ash and bottom ash from 11 municipal/ hazardous/industrial waste incinerators, using analytical standards synthesized in our laboratory. Concentrations of total ClPAHs and BrPAHs in ash samples ranged from
