Research on hexachlorobutadiene (HCBD) has increased since its listing in the Stockholm Convention on Persistent Organic Pollutants in 2011. However, thorough reports on recent data regarding this topic are lacking. Moreover, potential associations between HCBD and some chlorinated organics have usually been ignored in previous research. In this review, possible formation pathways and sources, current environmental occurrences and human exposure risks of HCBD are discussed, as well as the association with several organochlorine compounds. The results reveal that unintentional production and emission from industrial activities and waste treatments are the main sources of HCBD. Similar precursors are found for HCBD and chlorobenzenes, indicating the presence of common sources. Although recent data indicates that levels of HCBD in the environment are generally low, risks from human exposure to HCBD, together with other pollutants, may be high. More attention in the future needs to be paid to the mixed contamination of HCBD and other pollutants from common sources.
六氯丁二烯（HCBD）自 2011 年被列入《关于持久性有机污染物的斯德哥尔摩公约》以来，其相关研究不断增加。然而，目前缺乏关于该主题的最新数据的全面报告。此外，在以前的研究中，HCBD 与一些氯化有机物之间的潜在关联通常被忽略。在这篇综述中，讨论了 HCBD 的可能形成途径和来源、当前的环境出现情况和人类暴露风险，以及与几种有机氯化合物的关联。结果表明，工业活动和废物处理中的无意生产和排放是 HCBD 的主要来源。HCBD 和氯苯有相似的前体，表明存在共同的来源。尽管最近的数据表明环境中 HCBD 的水平通常较低，但人类接触 HCBD 以及其他污染物的风险可能很高。未来需要更加关注来自共同来源的 HCBD 和其他污染物的混合污染。
