摘要:
为了解灌河口工业区表层土壤中多环芳烃的污染水平及健康风险。于2017年4月份在灌河口化工园区、火力发电厂和钢铁工业园区采集30个表层土壤样品,利用气相色谱-质谱联用仪(GC-MS)对16种优控ω(PAH)进行了检测。结果表明,30个采样点16种PAH的ω(T-PAHs)为1 212.8~12 264.5 ng/g,平均值为3 504.8 ng/g。其中单体PAH以Fl为主,平均比例高达19.4%,其次为Pyr(16.7%)和B[a]P(9.6%)。单体PAH相关性分析表明了污染物来源的一致性,主要来源于本地工业区原油、生物质和煤的燃烧过程。根据加拿大土壤环境质量标准,灌河口工业区87%的土壤PAHs污染超过了安全值,存在潜在的生态风险。

Abstract:
In order to clarify the pollution level and health risks of polycyclic aromatic hydrocarbons(PAHs) in surface soil of Guan River Estuery Industrial Area, 30 surface soil samples were collected from the study area, and 16 kinds of priority control PAH were detected by gas chromatography mass spectrometry(GC MS). The results showed that the total concentration of 16 kinds of PAH(T PAHs) in 30 sampling sites ranged from 1 212.8 to 12 264.5 ng/g, with an average concentration of 3 504.8 ng/g. The monomer PAH was dominated by Fl, with an average ratio of 19.4%, followed by Pyr(16.7%) and B[a]P(9.6%). The correlation analysis of monomer PAH suggested that the consistency of pollution sources, and the characteristic ratio indicated that PAHs originated from crude oil, biomass and coal combustion processes in local industrial areas. According to the Canadian soil environmental quality standards, 87% of sampling sites in the industrial area of Guan River Estuary exceeded the safe value, and there is a potential ecological risk.
