摘　　要：多氯萘(PCNs)具有和二口恶英类(PCDD/Fs)相似的结构和毒性,在全球的环境和生物样品中都能被检测到.本文介绍了环境中PCNs的主要来源和环境归宿,重点介绍了焚烧和金属冶炼等过程中PCNs的排放特征,归纳了当前全球环境介质和生物体中PCNs的污染水平和分布特征,对我国多种环境介质和生物体中PCNs污染水平和分布特征的相关研究进行了归纳和讨论.最后提出了PCNs相关研究领域研究进展与面临的挑战.Due to the structural similarity to dioxins, polychlorinated naphthalenes （PCNs） exhibit toxicological properties similar to dioxins. Studies have suggested that the dioxin-like activity of PCNs was comparable with that of dioxins in some locations. PCNs have attracted increasing attention because of their potential adverse effects on the global environment and human health. This review focuses on main sources and environmental behavior of PCNs, especially the unintentionally produced PCNs during industrial processes. The contamination levels and distribution of PCNs in global environmental matrices were summarized. The progress in the studies associated with the environmental level and characteristics of PCNs in China were also evaluated. Finally, the challenges of PCNs related studies were discussed.
