ABSTRACT:
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, 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 suspended organic matter (suspended particles) 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 technical note on the method: just for experimental convenience, the author of the paper made the suspension of organic matter in water by adding the cells of S. cerevisiae; these cells are not normally present in sea water; however they were used just as a convenient model of organic particles suspended in water. A special experiment demonstrated that the kinetics of their removal from water by marine bivalves was identical to the kinetics of the removal of phytoplankton cells].
