Coastal contamination in the 1940s was assessed based on analysis of canned blue mussels presumably collected from Birch Harbor, Maine, USA. Analytical results on legacy organic contaminants were compared to long-term National Oceanic and Atmospheric Administration (NOAA) Mussel Watch (MW) monitoring data to estimate the degree of coastal contamination before World War II (WWII) when many synthetic organic compounds were first introduced into the environment. While dieldrin and chlordane were not detected in the canned mussels, dichloro-diphenyl-trichloroethane (DDT) and hexachlorocyclohexanes (HCHs) were present at lower concentrations relative to the more recent MW data. Polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs) were detected, and the later were significantly higher in canned mussels relative to the MW data (p<0.05). Furthermore, moving average analysis applied to the MW data depicted three-phased temporal trend patterns (increase-decrease-steady state) for virtually all contaminants indicating an overall increased coastal contamination in post WWII era.
20 世纪 40 年代的沿海污染情况是基于对美国缅因州伯奇港（Birch Harbor）采集的罐装贻贝进行分析得出的。将有关传统有机污染物的分析结果与长期的国家海洋和大气管理局（NOAA）贻贝监测（MW）监测数据进行了比较，以估算二战前（WWII）的沿海污染程度，当时许多合成有机化合物首次被引入环境。虽然在罐装贻贝中未检测到狄氏剂和氯丹，但滴滴涕（DDT）和六氯环己烷（HCHs）的浓度相对近期的 MW 数据较低。检测到多氯联苯（PCBs）和多环芳烃（PAHs），并且与 MW 数据相比，罐装贻贝中的多环芳烃含量显著更高（p<0.05）。此外，MW 数据的移动平均值分析显示，几乎所有污染物都呈现出三阶段时间趋势模式（增加-减少-稳定状态），表明二战后沿海污染总体增加。
