【摘要】 有关持久性有机污染物(POPs)的研究已经成为环境化学与生态毒理学研究的热点.根据国内外的研究现状,简要介绍了POPs的定义、性质、对生物的影响、来源、在全球范围内的迁移转化和生物富集作用以及目前的处理技术;在现有资料的基础上,总结了我国部分地区POPs污染现状;对当前POPs研究中的一些问题做了简单地探讨,提出POPs给传统污水处理工艺带来的挑战,针对研究今后的发展方向提出了一些见解.更多还原

【Abstract】 Research on persistent organic pollutants (POPs) has been becoming a fascinating area in the field of environmental chemistry and ecotoxicology. This paper, on the base of situation in this focus both home and abroad, is aiming to provide a brief discussion on POPs’ definition and properties、effect on organisms、 source、 transportation and conversion and bioaccumulation as well as treatment techniques. Besides, the paper also reveals POPs pollution in some regions in our nation based on the available research achievements. Afterward, some problems in research on POPs at present are discussed concisely. Some challenges generated by POPs to conventional sewage or wastewater treating processes are exhibited simultaneously. Some reviews and tentative plans on certain directions in development of this scientific research are also presented.更多还原
