S.A.Ostroumov For the first time, oysters were used as the test-organisms in bioassay of synthetic surfactants. As surfactants are one of key components of water pollution from municipal waste waters, from ports and ships, the new data revealed a novel type of hazard to mariculture of oysters. New negative effects of several amphiphilic chemicals (surfactants) and chemical mixtures on oysters and other marine bivalves were discovered. An anionic surfactant, sodium dodecylsulphate (SDS), and a cationic surfactant, tetradecyltrimethylammonium bromide (TDTMA) inhibited water filtering activity of oysters (Crassostrea gigas). Similar effects were exhibited by some chemical mixture products (detergents) that included surfactants as components of the mixtures. Those mixture products inhibited filtering activity by Crassostrea gigas and Mytilus galloprovincialis. The mixture products tested were: the SD1(L), Lanzaautomat (Benckiser); SD2(I), IXI Bio-Plus (Cussons); LD1 (E), dish washing liquid E (Cussons International, Ltd.); and LD2 (F), dish washing liquid Fairy (Procter & Gamble, Ltd.). 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. The filtering activity contributes to improving water quality. This experimental approach is helpful in assessment of environmental hazard from man-made chemicals that contaminate marine ecosystems.

A. Ostroumov Presented by Academician M.E. Vinogradov October 9, 2000;Received October 17, 2000; Moscow State University, Vorob’evy gory, Moscow, 119991 Russia;It has been previously shown that some amphiphilic chemicals (surfactants) and surfactantcontaining chemical mixtures affect filtering activity of mussels [1, 2]. Taking into account theecological importance of this effect [3–6], it was of interest to broaden the view of this problemand to determine whether organisms important for aquiculture may be affected by thesecompounds. Bivalves are the most important cultured marine species. It was shown that theaverage annual production of marine bivalves grown in aquaculture significantly exceed that of marine fish (9.7-fold) and Crustaceans (4fold) grown in mariculture [7]. Owing to the importanceof mariculture, it is necessary to determine the factors that may disturb physiological activity of objects grown in mariculture (including bivalves) and deteriorate their living and culturingcondition s.The goal of this study was to determine whether surfactants and surfactantcontainingchemic al mixtures inhibit the filtering activity of bivalves grown in mariculture, particularlyoysters Crassostrea gigas Thunberg (= Ostrea laperousi auct.).The experiments were performed according to the previously described procedure [2] withsome modifications. The filtration rate was determined by the decrease in optical density of theincubation medium at 550 nm as a result of removal (due to filtration) of Saccharomycesce revisiae cells that were preliminarily added to the marine water. The concentration of S.cerevisiae cells (SAFMoment, S.I. Lesaffre, 59703 Marcq-France) was 100 mg/l (dry weight).The temperature is indicated in the tables. The optical density was measured using a SF-26 LOMOspectropho tometer, the optical way length was 10 mm. The average weight of the oysters and thevolume of the incubation medium are indicated in the notes to the tables. The oysters were grownat the mariculture farm of the Institute of South Sea Biology (National Academy of Sciences of Ukraine) and the State Oceanarium of Ukraine.We analyzed the effects of sodium dodecyl sulfate (SDS), tetradecyltrimethy lammonium brom ide (TDTMA), several synthetic detergents (SDs), and liquid detergents (LDs). In this paper,the following denotations are used: SD1(L), Lanza-automat (Benckiser); SD2(I), IXI BioPlus(Cussons); LD1 (E), dish washing liquid E (Cussons International, Ltd.); and LD2 (F), dishwashing liquid Fairy (Procter & Gamble, Ltd.).We discovered that a typical cationic surfactant containing a tertiary ammonium group,TDTMA, inhibited the filtering activity of C. gigas (Table 1). The yeast suspension concentrationdiffe red from the control more than twofold and more than sevenfold 5 and 20 min after the addition of TDTMA, respectively. Table 1.
