| Abstract: | The activity of acid phosphatase of some freshwater mollusks was examined and correlated with the quality of water in the laboratory experiment and in their natural habitats. The results were compared with the traditional indices of water pollution (oxygen content, chemical and biochemical oxygen demand, the survival rate of daphnia, changes in the microalga population in tests, the diversity of macrozoobenthos species under natural conditions). The performed experiments and observations show that the activity of acid phosphatase of mollusks features a sufficient sensitivity for biochemical testing and biochemical indication of pollution and can be used for environmental monitoring of inland waters in addition to commonly accepted protocols. |
