The ability of whole effluent toxicity (WET) tests to predict in-stream effects to periphyton, benthic macroinvertebrates, and fish in a habitat-impaired stream was assessed. Habitat assessment data were useful in interpreting in-stream conditions for periphyton and benthic macroinvertebrates. Various periphyton and macroinvertebrate metrics identified siltation effects as opposed to water quality effects in-stream. Pathogen effects noted in fathead minnow WET tests were not reflected in the fish community. Overall, in-stream biological conditions confirmed the absence of water quality-related effects as predicted by WET tests.
评估了全排放毒性(WET)测试预测受损生境溪流中对周丛生物、底栖大型无脊椎动物和鱼类的溪流内影响的能力。生境评估数据有助于解释周丛生物和底栖大型无脊椎动物的溪流内状况。各种周丛生物和大型无脊椎动物指标确定了淤积影响,而非溪流内的水质影响。黑头呆鱼WET测试中记录的病原体影响未在鱼类群落中体现。总体而言,溪流内生物状况证实了WET测试所预测的与水质相关影响不存在。
