Abstract

In this study, the polycyclic aromatic hydrocarbons (PAHs) organic pollutants in soil samples were determined by Soxhlet extraction- GCMS methods. Human health risks of as for 5 different sampling sites in the coking chemical plant were evaluated in four major Exposure routes, including oral intake, skin contact, inhalation the air pollutants of outdoor which from the soil surface, and inhalation the air pollutants of outdoor which from the soil lower layer. The results showed that the detection rate of 16 kinds precedent- controlled PAHs in the US Environmental Protection Agency was 100%. The three main pollutants are Baa, Bbf, Bap. The ΣPAHs comprehensive carcinogenicity risk of the oral exposure pathway is 498 times the carcinogenic risk of the skin exposure pathway, and 198 times the rate of carcinogenic risk of inhalation of soil particle Exposure route. And the rate of carcinogenic risk of Inhalation the air pollutants of outdoor which from the soil lower layer is almost 0. The hazard quotient of soil ΣPAHs main air pollutants pathway are oral intake and inhalation of outdoor air from the soil surface. The sum of them is close to 90%, The hazard quotient of soil ΣPAHs in the coking plant area is seriously exceeded. The risk of ΣPAHs in the soil of coking plant was mainly exposed to oral intake, and the contribution rate of carcinogenic risk was 99.3103%. Combined with the development characteristics of China's coking industry, regional climate and geological characteristics, make a human health risk assessment to ΣPAHs.
