Content and Source Apportionment of Polycyclic Aromatic Hydrocarbons in Surface Soil in Major Areas of China
摘要
Abstract
To scientifically control the pollution of polycyclic aromatic hydrocarbons (PAHs) in soils, content, composition and sources of PAHs in main areas of surface soils in Chins from 101 papers published from 2000—2016 were systematically analyzed. The results showed that the total polycyclic aromatic hydrocarbons (?PAHs) concentration (median value) was 515.70 ng·g-1 in main areas of China, which was in the medium level compared with other countries. The content (median value) of phenanthrene (Phe), fluoranthene (Fla) and naphthalene (Nap) in surface soil were relatively higher among 16 kinds of PAHs and acenaphthylene (Acy), acenaphthene (Ane) and indene benzo (1, 2, 3-CD) pyrene (Inp) were relatively low. The content of?PAHs (median value) from high to low in the order of Northwest China, North China, Northeast China, East China, Central China, South China and Southwest China. 4 rings and above of PAHs are dominated in surface soil which accounted 60.06%, the composition of PAHs in different areas was different. Through the cluster analysis of 16 kinds of detected PAHs, it is concluded that PAHs in China mainly consists of five sources: coal combustion, oil fuel burning, tar production, oil and biomass combustion. Combined with the isomer ratio and the characteristic of the pollutant index method, cluster analysis of PAHs in 22 provinces and autonomous regions showed that the PAHs in surface soils of Xinjiang, Tinjin and Shanxi mainly origin from liquefied petroleum fuels and oil pollution with gasoline as main ingredient. PAHs in surface soil of Fujian, Jilin, Shanxi, Guizhou and Jiangxi mainly came from combustion of grass, wood, coal and biomass. PAHs in surface soil of Beijing, Hubei, Heilongjiang, Anhui, Xizang, Jiangsu, Guangdong, Zhejiang, Hunan, Shandong, Ningxia, Chongqing and Hong Kong mainly origin from combustion of liquid fossil fuels, biomass and coal with coal and gasoline as components.关键词
