Ostroumov S. A. Identification of a New Type of Ecological Hazard of Chemicals:

Inhibition of Processes of Ecological Remediation . - Doklady Biological Sciences, Vol. 385, 2002, pp. 377–379. Translated from Doklady Akademii Nauk, Vol. 385, No. 4, 2002, pp. 571–573.

The author discovered and characterized a new type of ecological hazard of chemical pollution of water, which involves inhibition of important processes of ecological remediation of ecosystems (water filtration by aquatic bivalves). Experiments were performed using mollusks (oysters), Crassostrea gigas Thunberg, and a cell suspension of Saccharomyces cerevisiae. The cell suspension was a model of suspended matter in aquatic ecosystem. Laundry detergent Lanza-Automat inhibited water filtration by oysters (Crassostrea gigas). As a result, the removal of the cells (Saccharomyces cerevisiae) from water was inhibited. This demonstrated  a new type of ecological hazard caused by water pollution with chemical pollutants at sublethal concentrations. This hazard is associated with the fact that chemical pollution of water

causes inhibition of the physiological activity of filter-feeders, thereby inhibiting the important ecological processes of water filtration. These ecological processes contribute significantly to improving water quality, water purification and the related remediation of aquatic ecosystems (their ecological repair). ---http://scipeople.ru/users/2943391/;
