摘要: BTEX是苯(benzene)、甲苯(toluene)、乙苯(ethylbenzen)和二甲苯(xylene)的统称,存在于原油和石油产品中,同时作为化工原料应用于农药、塑料及合成纤维等制造业。BTEX广泛存在于大气、水体和土壤等环境介质,对相应的生态系统和人类健康产生严重危害。本文分析了各环境介质中BTEX的来源及分布特征,探讨了其在各种环境系统间的迁移和转化规律,重点从生殖发育毒性方面讨论了BTEX产生的人体健康效应,最后对今后研究重点进行了探讨。

Abstract: BTEX are a general designation of benzene, toluene, ethylbenzene and xylene, which are commonly found together in crude oil and oil products. These compounds are also produced as raw materials for the manufacture of pesticides, plastics and synthetic fibers. BTEX exist abroad in air, water and soil environment, and cause serious adverse effects on corresponding ecosystems as well as human health. Pollution sources and distribution characteristics of BTEX were analyzed in various mediums, and the transfer and transformation in environment were discussed. Influences on human health especially in the aspect of reproductive and developmental toxicity were reviewed. The pivots of further researches of BTEX were suggested.
