The mankind is still far from establishing harmonious relations with it. However, permanently progressing destruction of natural complexes by the technogenic civilization necessitates some new revolutionary approaches to their preservation. That is why it is so important to study the relationships and interactions between living organisms. One of the most important roles in this “orchestra” is played by numerous invertebrates which filter the water and improve water quality.

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).

A new fundamental principle was proved in the paper: to maintain the water quality, it is necessary to protect the functionally active biodiversity of water ecosystems. In other words, protection of the functionally active biodiversity of aquatic organisms in a water body is a method (and an indispensable one) of maintenance of water quality in this ecosystem. Also, the author reports new experimental data on how detergents inhibited filtration activity of marine bivalves, mussels Mytilus galloprovincialis, and oysters Crassostrea gigas.
