as largely dominated by opportunistic polychaetes; other taxa, including amphipods and bivalves (but not .), were less abundant. The PAHs often exceeded the effects range median (ERM) in US Sediment Quality Guidelines, indicating elevated ecotoxicological risk levels for the benthic invertebrates. N特征 发表于 2025-3-25 10:48:43
