Since only a few standard benthic test species are available for sediment quality, our study aimed to employ multiple test species representing different sensitivity categories in the quality assessment of contaminated sediments. To this end three macroinvertebrate species, Sericostoma personatum (caddisfly, sensitivity category 10), Asellus aquaticus (isopod, category 3) and Chironomus riparius (chironomid, category 2), were exposed to sediments originating from various contamination sources in whole sediment bioassays using intact sediment cores. The agricultural sediment caused insect mortality, the agricultural and urban sediment caused isopod growth reduction and the urban and Wastewater Treatment Plant (WWTP) sediment affected chironomid emergence time. It is concluded that the arsenal of standard species can be successfully expanded by non-standard species, reducing over- or underestimation of the risks of contaminated sediments.
由于可用的标准底栖测试物种数量有限，我们的研究旨在使用代表不同敏感类别的多种测试物种来评估受污染沉积物的质量。为此，我们使用完整的沉积物芯在整个沉积物生物测定中，将三种大型无脊椎动物物种（Sericostoma personatum （毛翅目，敏感类别 10）、Asellus aquaticus （等足目，类别 3）和 Chironomus riparius （摇蚊目，类别 2）暴露于来自各种污染源的沉积物中。农业沉积物导致昆虫死亡，农业和城市沉积物导致等足目生长减少，而城市和污水处理厂（WWTP）沉积物则影响摇蚊的出现时间。因此得出结论，通过非标准物种可以成功扩展标准物种的武器库，从而减少对污染沉积物风险的过高或过低估计。
