In connection with installation of two natural gas pipelines through the Baltic Sea between Russia and Germany, there has been concern regarding potential re-suspension of historically dumped chemical warfare agents (CWA) in a nearby dump site and the potential environmental risks associated. 192 sediment and 11 porewater samples were analyzed for CWA residues, both parent and metabolites in 2008 and 2010 along the pipeline corridor next to the dump site. Macrozoobenthos and background variables were also collected and compared to the observed CWA levels and predicted potential risks. Detection frequencies and levels of intact CWA found were low, whereas CWA metabolites were more frequently found. Re-suspension of CWA residue-containing sediment from installation of the pipelines contributes marginally to the overall background CWA residue exposure and risk along the pipeline route. The multivariate weight-of-evidence analysis showed that physical and background parameters of the sediment were of higher importance for the biota than observed CWA levels.
在俄罗斯和德国之间通过波罗的海铺设两条天然气管道的过程中，人们对附近倾倒场中历史上倾倒的化学战剂（CWA）可能再次悬浮以及相关的潜在环境风险表示关注。2008 年和 2010 年，在倾倒场旁边的管道走廊沿线，192 个沉积物和 11 个孔隙水样被分析了 CWA 残留物，包括母体和代谢物。还收集了大型底栖动物和背景变量，并将其与观察到的 CWA 水平和预测的潜在风险进行了比较。发现完整 CWA 的检出频率和水平较低，而 CWA 代谢物则更频繁地被检出。管道安装过程中倾倒场中含有 CWA 残留的沉积物的再悬浮对管道沿线的总体背景 CWA 残留暴露和风险的贡献很小。多变量证据权重分析表明，与观察到的 CWA 水平相比，沉积物的物理和背景参数对生物群更为重要。
