The attack on the World Trade Center (WTC) resulted in the destruction of buildings, and the release of tons of dust and debris into the environment. As part of the effort to characterize the environmental impact of the WTC collapse, Mussel Watch Program trace element measurements from the Hudson-Raritan Estuary (HRE) were assessed for the years before (1986-2001) and after (2001-2005) the attack. Trace element measurements in the HRE were significantly higher than Mussel Watch measurements taken elsewhere in the Nation. Post-attack trace element measurements were not significantly different from pre-attack measurements. The impacts of WTC collapse may have been obscured by high ambient levels of trace elements in the HRE.
世界贸易中心（WTC）遇袭导致两座大楼被毁，大量灰尘和碎片被释放到环境中。为了描述 WTC 倒塌对环境的影响，研究人员评估了哈德逊-拉瓜迪亚河口（HRE） Mussel Watch 项目微量元素测量数据，这些数据来自袭击发生之前（1986-2001 年）和之后（2001-2005 年）。HRE 的微量元素测量值明显高于 Mussel Watch 项目在全美其他地区的测量值。袭击后的微量元素测量值与袭击前的测量值没有显著差异。HRE 中环境背景下的高浓度微量元素可能掩盖了 WTC 倒塌的影响。
