我国石油炼化行业特征污染物及其健康风险分析
Analysis of characteristic pollutants and health risks in the petroleum refining industry in China
摘要
Abstract
Petroleum refining is an important pillar industry of China's national economy.However,the phenomena of"running,bubbling,dripping and leaking"in the process of processing,refining,storage and transportation have caused soil and groundwater pollution,which poses a certain risk to human health.By combing the spatial distribution characteristics of domestic petroleum refining enterprises and relevant pollution investigation literature,this study analyzed the typical pollutants in China's petroleum refining industry,and analyzed the exposure characteristics of typical pollutants and their potential health risks.The results showed that the petroleum refining industries in China were unevenly distributed in coastal areas mostly and less in inland areas.The sites were mainly polluted by the mixed organic-inorganic or organic-organic compounds,with total petroleum hydrocarbon(TPH)and heavy metals as dominant pollutants in soil,while TPH and BTEX mainly in groundwater.On the one hand,the results of risk characterization showed that TPH(38％),xylene(33％)and benzene(12％)in soils could introduce notable noncarcinogenic health risk with the highest hazard quotient(HQ)of 19.1 for TPH,and the carcinogenic risks(CR)of benzene(41％),ethylbenzene(29％)and nickel(11％)were much higher than other pollutants,with the highest CR of 1.05×10-4 for benzene.On the other hand,the highest HQ for TPH was up to 75.9,while the highest CR for benzene reached 1.84×10-5.Therefore,controlling the non-carcinogenic hazards and carcinogenic risks of TPH and BTEX is the key for the remediation of soil and groundwater contamination in petroleum refinery sites.关键词
