Detecting the concentration of polycyclic aromatic hydrocarbon (PAHs) in aerosol, e.g., PM2.5 and PM10, is important for monitoring and possibly improving air quality. To fully understand the concentration distribution of polycyclic aromatic hydrocarbon in aerosol, five sampling locations were selected. A carefully designed experiment was carried out to determine the concentration of polycyclic aromatic hydrocarbon in aerosol samples, using gas chromatography-mass spectrometry (GC-MS) . It is found that the concentration of Benzoapyrene, which has strong carcinogenicity, is 1.03~23.35 ng/m 3 and 0.24~18.75 ng/m 3 in PM10, PM2.5. The average values were 5.07 ng/m 3 and 3.91 ng/m 3 , indicating a serious concern for the air quality. Such level of Benzoapyrene poses threat to the surrounding environment, especially, to the workers health. Results from this study are important and can be used by decision makers for better monitor.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
