The experiment was conducted to analyze content and distribution of sixteen kinds of polycyclic aromatic hydrocarbons(PAHs) pollutants in 20 soil samples taken from Jurong,Jiangsu Province.The results showed that the total content of PAHs in soil ranged from 5.15-375.19 μg/kg,out of which the content of Flt was the highest.Compared with Tibet,Beijing,Tianjin and Shantou,the PAHs pollution was moderate in Jurong region.The PAHs with three rings were dominant,and Flt,Phe and Cry were the main pollutants.The main source of PAHs in the study area was combustion of straws,fire woods and coal which are closely related to human activities.Due to nearby major traffic roads,the source of PAHs in some soil samples was automobile exhaust.
