Review on the pollution of polychlorinated diphenyl ethers
多氯联苯醚类化合物污染研究进展

In this paper the research status of polychlorinated diphenyl ethers (PCDEs) was reviewed. The sources, toxic effects, pollution status, transformation and bioaccumulation, as well as formation mechanism of PCDEs were summarized. Because the research on PCDEs was lagged, it is necessary for China to carry out a series of studies on the environmental levels, ecological safety and toxicology of PCDEs.
