多卤代咔唑（phcz）是在环境母体中发现的新出现的全球污染物，例如，在五大湖的沉积物中已检测到3000吨phcz。对世界范围内正在进行的工业活动产生的PHCZ排放的认识仍然缺乏。在这里，我们确定并量化了13个大型工业的PHCZ排放，其中12个以前没有数据。澄清了所调查工业来源的PHCZ的同源剖面，从而可以分配PHCZ来源。主要工业的年PHCZ排放量是根据导出的排放因子估算的，然后绘制全球地图。焦炭生产是PHCZ的主要排放源，排放量为9229 g/年，其次是铁矿石烧结，PHCZ排放量为3237 g/年。中国、澳大利亚、日本、印度、美国和俄罗斯通过这些工业活动被发现是重要的排放国。PHCZ污染是一个潜在的全球性人类健康和环境问题。要了解多卤代咔唑的环境积累，需要对其来源进行认识。本文对13个行业包括122家工厂的多卤代咔唑的释放进行了鉴定和估计。
Polyhalogenated carbazoles (PHCZs) are emerging global pollutants found in environmental matrices, e.g., 3000 tonnes of PHCZs have been detected in the sediments of the Great Lakes. Recognition of PHCZ emissions from ongoing industrial activities worldwide is still lacking. Here, we identify and quantify PHCZ emissions from 13 large-scale industries, 12 of which previously have no data. Congener profiles of PHCZs from investigated industrial sources are clarified, which enables apportioning of PHCZ sources. Annual PHCZ emissions from major industries are estimated on the basis of derived emission factors and then mapped globally. Coke production is a prime PHCZ emitter of 9229 g/yr, followed by iron ore sintering with a PHCZ emission of 3237 g/yr. China, Australia, Japan, India, USA, and Russia are found to be significant emitters through these industrial activities. PHCZ pollution is potentially a global human health and environmental issue. Recognition on sources of polyhalogenated carbazoles is needed to understand their environmental accumulation. Here, release of polyhalogenated carbazoles from 13 industries including 122 plants is identified and estimated.
