The concern about emissions of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) polychlorinated biphenyls (PCBs), and polybrominated diphenyl ethers (PBDEs) from steel industrial parks has increased in the past decades. In this study, polyurethane foam (PUF)-disk based passive air samples were collected in and around a big steel industrial park of Anshan, Northeast China from June 2008 to March 2009. The levels, seasonal variations and potential sources of PCDD/Fs, PCBs and PBDEs in the atmosphere around the steel industrial complex were investigated, and potential contribution of these three groups of persistent organic pollutants (POPs) from iron and steel production was also assessed. The air concentrations of ∑(17)PCDD/Fs (summer: 0.02-2.77 pg m(-3); winter: 0.20-9.79 pg m(-3)), ∑(19)PCBs (summer: 23.5-155.8 pg m(-3); winter: 14.6-81.3 pg m(-3)) and ∑(13)PBDEs (summer: 2.91-10.7 pg m(-3); winter: 1.10-3.89 pg m(-3)) in this targeted industrial park were relatively low in comparison to other studies, which implied that the industrial activities of iron and steel had not resulted in serious contamination to the ambient air in this area. On the whole, the air concentrations of PCDD/Fs in winter were higher than those of summer, whereas the concentrations of PCBs and PBDEs showed opposite trends. The result from principal component analysis indicated that coal combustion might be the main contributor of PCDD/F sources in this area.
在过去几十年中，人们对钢铁工业园区排放的多氯二苯并对二恶英和呋喃（PCDD/Fs）、多氯联苯（PCBs）和多溴二苯醚（PBDEs）的关注度有所增加。本研究于 2008 年 6 月至 2009 年 3 月在我国东北地区的鞍山钢铁工业园区内外采集了基于聚氨酯泡沫（PUF）圆盘的被动式空气样本。研究了大气中 PCDD/Fs、PCBs 和 PBDEs 的水平、季节性变化和潜在来源，评估了钢铁生产过程中这三组持久性有机污染物（POPs）的潜在贡献。该钢铁联合企业周边空气中∑（17）PCDD/Fs（夏季：0.02-2.77 pg m(-3)；冬季：0.20-9.79 pg m(-3)）、∑（19）PCBs（夏季：23.5-155.8 pg m(-3)；冬季：14.6-81.3 pg m(-3)）和∑（13）PBDEs（夏季：2.91-10.7 pg m(-3)；冬季：1.10-3.89 pg m(-3)）的浓度与其他研究相比相对较低，这表明钢铁工业活动并未导致该地区环境空气中的严重污染。总的来说，冬季 PCDD/Fs 的空气浓度高于夏季，而 PCBs 和 PBDEs 的浓度则呈现相反的趋势。主成分分析的结果表明，煤炭燃烧可能是该地区 PCDD/F 来源的主要贡献者。
