Abstract
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.
期刊介绍：
Environmental Pollution is an international peer-reviewed journal that publishes high-quality research papers and review articles covering all aspects of environmental pollution and its impacts on ecosystems and human health.
Subject areas include, but are not limited to:
• Sources and occurrences of pollutants that are clearly defined and measured in environmental compartments, food and food-related items, and human bodies;
• Interlinks between contaminant exposure and biological, ecological, and human health effects, including those of climate change;
• Contaminants of emerging concerns (including but not limited to antibiotic resistant microorganisms or genes, microplastics/nanoplastics, electronic wastes, light, and noise) and/or their biological, ecological, or human health effects;
• Laboratory and field studies on the remediation/mitigation of environmental pollution via new techniques and with clear links to biological, ecological, or human health effects;
• Modeling of pollution processes, patterns, or trends that is of clear environmental and/or human health interest;
• New techniques that measure and examine environmental occurrences, transport, behavior, and effects of pollutants within the environment or the laboratory, provided that they can be clearly used to address problems within regional or global environmental compartments.
