Severely impacted streams will only have pollution tolerant macroinvertebrates. In this study, samples of water and macroinvertebrates were taken from several dozen sites in 14 rivers in China with different pollution levels, including the Yangtze, East, Weihe, Songhua, Yongding, and Panlong rivers. Norwegian watercourses are becoming increasingly acidified. By M Henry, S William and SN Miller. Most species are relatively abundant which means they are sufficiently abundant to be captured, They are relatively sedentary, so the occurrence of most can be related to conditions at the place of capture. Damselfly Larvae, Dragonfly Larvae, Aquatic Sowbug, Scud, Beetle Larvae, Clams, Leech, Aquatic Worms, Midge Larva, Pouch Snail, Black Fly Larvae. Macroinvertebrates respond to environmental stress so the presence or absence of a particular species can indicate the presence of an environmental stressor such as pollution. Use of benthic macroinvertebrates for assessment of impact of canalization on water quality of river Ganga (Bhagirathi). To do this, they often sieve the water through rows of tiny hairs. The various species show a range of pollution sensitivity/ tolerance.
