Hexachloro-1,3-butadiene (HCBD) has received increasing attention because of its adverse effects on human health. Although HCBD is regulated under the Stockholm Convention, it is still widely detected in the environment. However, detailed reports on the chemical mechanisms of HCBD reactions in the environment are lacking. This review comprehensively summarizes HCBD's unintentional industrial sources and formation mechanisms, and chemical reactions and transformations in different media (gas, water, and biological phases). Photochemical reactions in the atmosphere can degrade and transform HCBD and potentially form other toxic compounds, such as phosgene. Aerobic pyrolysis of HCBD can generate complex byproducts. Further research is essential to fully understand the environmental behavior of HCBD.
六氯-1,3-丁二烯（HCBD）因其对人类健康的不良影响而受到越来越多的关注。尽管 HCBD 受到《斯德哥尔摩公约》的管制，但它仍在环境中广泛存在。然而，关于 HCBD 在环境中的化学反应的详细报告仍然缺乏。本综述全面总结了 HCBD 的非故意工业来源和形成机制，以及在不同介质（气体、水和生物相）中的化学反应和转化。大气中的光化学反应可以降解和转化 HCBD，并可能形成其他有毒化合物，如光气。HCBD 的需氧热解可以生成复杂的副产物。需要进一步研究才能充分了解 HCBD 的环境行为。
