ABSTRACT: Effects of several chemicals, synthetic surfactants and chemical mixtures, on marine bivalves were studied. An anionic surfactant, sodium dodecylsulphate (SDS), and a cationic surfactant, tetradecyltrimethylammonium bromide (TDTMA), inhibited the filtering activity of marine bivalves, oysters (Crassostrea gigas). Similar effects were exhibited by some chemical mixtures that included surfactants. Those mixtures inhibited the filtering activity of Crassostrea gigas and marine mussels Mytilus galloprovincialis. The new results are in agreement with the author's previous experiments, where a number of xenobiotics and/or pollutants inhibited the filtering activity of several species of marine and freshwater bivalves, e.g., it had been shown that SDS inhibited filtering activity of marine mussels Mytilus edulis (e.g., Ostroumov, 2000c, 2001a). This experimental approach is helpful in assessment of environmental hazards from man-made chemicals that can contaminate marine systems. The importance of the findings:
1) It is the first discovery of serious environmental hazards from synthetic surfactants and chemical mixtures that contain surfactants, especially in view of the fact that filtering activity of bivalves is an important part of water self-purification and the natural mechanism for maintaining water quality;
2) It is a new evidence of serious environmental hazards from relatively mild, sublethal effects of chemical pollutants;
3) It is relevant to aquaculture and mariculture. The new data discovered a new man-made impact on aquatic systems that poses a threat to aquaculture.
