Abstract

Abstract

In order to study the pollution characteristics of polycyclic aromatic hydrocarbons (PAHs) in urban top soil of Shenyang, 74 urban top soil samples were collected from the urban area of Shenyang in September 2017, the concentrations of 16 prior PAHs were determined, and the health risks were evaluated by probabilistic risk models based on Monte Carlo simulation. The results showed that, the concentrations of 16 PAHs ranged from 283 to 21821 μg/kg, with an average concentration of 2370 μg/kg. Compared with other researches, the pollution extent of PAHs in urban top soil of Shenyang was serious. The results of health risk assessment showed that, the total carcinogenic and non-carcinogenic risks caused by PAHs for children and adults were presented at an acceptable level. Among them, benzo[a]pyrene was the key contributor for carcinogenic risk, while pyrene, fluoranthene and phenanthrene were the key contributors for non-carcinogenic risk.
