| Abstract |
Using as examples water bodies in different geographical zones (Lake Ladoga, the River Sukhona, shallow-water ponds of the North Caucasus) the known methods of water quality evaluation by means of oligochaetes are considered. There is no unique universal method of pollution bio-indication in this way. In water bodies of all types the mass development of oligochaetes and the reduction of their species diversity are indications of: (1) large quantities of organic matter; (2) favourable oxygen regime; (3) absence or insignificant quantity of heavy metal solids, petroleum substances and agricultural chemicals; (4) intensive self-purification of the water body. |
