山西省典型燃煤污染區(qū)土壤中多環(huán)芳烴風(fēng)險評價
[Abstract]:A total of 128 topsoil samples were collected from the representative area of coal-burning pollution (1034 km~2) in the southern part of Linfen City, Shanxi Province. The contents of 16 PAHs (PAHs) in the soil were analyzed by gas chromatography-mass spectrometry (GC-MS). The ecological risk and human health risk of PAHs in the samples were evaluated. The results showed that the mass fraction of PAHs was (723.2 鹵1 230) 渭 g kg~ (- 1). According to the criteria of Maliszewska-Kordybach classification, 78.12% of the samples in the studied soil were polluted by PAHs in different degrees. Based on the evaluation results of Nemero comprehensive pollution index method, 83.59% of the sample sites in the studied area had PAHs pollution, and more than 60% of the sampling sites in ancient and new towns had reached the severe pollution level. The results of ecological risk assessment based on the risk assessment method of toxicity equivalent factor (Toxic Equivalency Factor,TEF) showed that the toxicity equivalent concentration (Bap toxic equivalent quantity, of benzo (a) pyrene (Bap) of 10 kinds of PAHs involved in the Netherlands soil quality standard. The TEQ_ (Bap) was (67.50 鹵137.7) 渭 g kg~ (- 1), and 42.19% of the samples exceeded the standard limit of TEQ_ (Bap10) in Dutch soil. The PAHs in ancient and new towns exceeded 3 times on average. The non-carcinogenic risk and carcinogenic risk of exposed population in the study area were evaluated respectively. The results showed that PAHs in the soil of the study area had no obvious non-carcinogenic risk to adults and children. But in ancient towns, new towns, Tao Si township, JingMao township and Yonggu township, the comprehensive carcinogenic risk caused by PAHs in soil has exceeded the acceptable carcinogenic risk (10 ~ (- 6), poses a potential threat to human health and needs to be paid attention to; The risk of carcinogenesis in other study areas is still within acceptable range (10 ~ (- 6).
