Ash-laden runoff samples collected near Ground Zero soon after the September 11, 2001 attack on the World Trade Center (WTC) and subsequent fire demonstrate the release of polychlorinated biphenyls (PCBs), polybrominated dipheyl ethers (PBDEs), polybrominated dibenzo-p-dioxins and polybrominated dibenzofurans (PBDD/Fs), polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs), and tetra- and pentachlorinated biphenylenes (PCBPs) from the incident. Relative abundances of PCDD/F congeners in the runoff water and post-disaster lower Manhattan dust samples were different from those seen in pre-disaster NYC combined sewer outfall (CSO) samples. The WTC-related samples showed a greater relative abundance of 2,3,4,7,8-PeCDF than usually seen in CSOs, sludges, and treated wastewaters. This congener may be associated with certain types of incineration. Comparison of sediment and water samples collected in the lower Hudson River before and shortly after September 11, 2001 (9/11) showed no changes in PCB or PCDD/F concentrations or homologue profiles determined down to the parts per quadrillion range. Comparisons of ambient water samples collected post-9/11 with archived samples suggest that the WTC disaster did not significantly impact ambient concentrations of the target chemicals. Ambient concentrations of PBDD/Fs in New York Harbor are similar to those of PCDD/Fs, suggesting that these contaminants deserve increased scrutiny with respect to toxicity, sources, and fate in the environment.
2001年9月11日世贸中心（WTC）遭受袭击及随后发生火灾后不久，在“零地带”附近采集的富含灰烬的径流样本表明，此次事件释放了多氯联苯（PCBs）、多溴二苯醚（PBDEs）、多溴二苯并对二恶英和多溴二苯并呋喃（PBDD/Fs）、多氯二苯并对二恶英和多氯二苯并呋喃（PCDD/Fs）以及四氯和五氯联苯（PCBPs）。径流水中和灾后曼哈顿下城灰尘样本中PCDD/F同系物的相对丰度与灾前纽约市合流污水排放口（CSO）样本中的不同。与世贸中心相关的样本显示，2,3,4,7,8-五氯二苯并呋喃的相对丰度高于CSO、污泥和经处理废水中常见的水平。该同系物可能与某些类型的焚烧有关。对2001年9月11日（9/11）之前和之后不久在哈得逊河下游采集的沉积物和水样进行比较，结果表明，在万亿分之一的范围内，PCB或PCDD/F的浓度及同系物分布没有变化。将9/11之后采集的环境水样与存档样本进行比较表明，世贸中心灾难并未对目标化学品的环境浓度产生显著影响。纽约港中PBDD/Fs的环境浓度与PCDD/Fs相似，这表明这些污染物在毒性、来源和环境归宿方面值得进一步审查。
