南极洲麦克默多站附近受污染海洋区域的 10 个底栖动物类群被认为是潜在的生物监测器，因为它们组织中的 PCB、DDT、PAH、铜、铅和/或锌显着高于生活在参考区域的类群组织中的含量 (p < 0.05)。 PCBs 和 DDT 的浓度在吸虫（鱼）中最高。总 PAH 浓度最高的是 Alcyium antarcticum（软珊瑚）、Isotealia antarctica（海葵）和 L.椭圆形。铜和铅的浓度在Laternula elliptica（双壳类）和Flabegraviera mundata（多毛类）中最高，而在Trematomus 和Parbolasia corrugatus（纽虫类）中最低。然而，小行星 Perknaster fuscus antarcticus、Odontaster validus 和 Psilaster charcoti 中的铜浓度甚至更高。不同物种的生物累积因子中 PCB 和 DDT 最高，铅最低。一些污染物的生物累积可能在麦克默多站的底栖类群中普遍存在，但相对于人类消费标准而言，浓度通常较低。
Ten benthic fauna taxa in a polluted marine area adjacent to McMurdo Station, Antarctica were deemed to be potential biomonitors because PCBs, DDTs, PAHs, copper, lead and/or zinc in their tissues were significantly higher than in tissues of taxa living in reference areas (p< 0.05). Concentrations of PCBs and DDT were highest inTrematomus(fish). Total PAH concentrations were highest inAlcyonium antarcticum(soft coral),Isotealia antarctica(anemone) andL. elliptica. Copper and lead concentrations were highest inLaternula elliptica(bivalve) andFlabegraviera mundata(polychaete), and lowest inTrematomusandParbolasia corrugatus(nemertean). However, copper concentrations were even higher in the asteroidsPerknaster fuscus antarcticus, Odontaster validusandPsilaster charcoti. Bioaccumulation factors for different species were highest for PCBs and DDT, and lowest for lead. Bioaccumulation of some contaminants are likely prevalent in benthic taxa at McMurdo Station, but concentrations are usually low relative to human consumption standards.
