The sensitivity of harpacticoid copepods was tested against selected pollutants. Acute toxicity tests were carried out for five hyporheic species exposed to pesticides, ammonia, and metals. The stygoxene Bryocamptus zschokkei, B. minutus, B. pygmaeus and Attheyella crassa; and the stygophilous B. echinatus were sampled and cultured during 8 months in controlled conditions. A first test protocol is presented. The acute endpoints among species fell within one order of magnitude. The sensitivity among various species evaluated in this study is consistent and the choice of species for further sediment/groundwater assessment is not specific to a chemical class. These potential test organisms would be more suitable to protect meiofaunal communities.
对猛水蚤目桡足类动物针对选定污染物的敏感性进行了测试。对暴露于农药、氨和金属的五种潜流物种进行了急性毒性试验。采集了穴居性的泽氏苔藓猛水蚤、微小苔藓猛水蚤、侏儒苔藓猛水蚤和粗壮阿特猛水蚤，以及喜穴居的棘刺苔藓猛水蚤，并在可控条件下培养了8个月。给出了首个测试方案。各物种间的急性终点落在一个数量级范围内。本研究中评估的不同物种间的敏感性是一致的，并且为进一步的沉积物/地下水评估选择物种并非特定于某一化学类别。这些潜在的测试生物将更适合用于保护小型底栖动物群落。
