An amphiphilic substance inhibits the mollusk capacity to filter out phytoplankton cells from water. - Biology Bulletin (=Biology Bulletin of the Russian Academy of Sciences), 2001, Volume 28, Number 1, p. 95-102. The effect of synthetic anionic surfactant sodium dodecylsulfate (SDS, 4 mg/l) on the kinetics of water filtration by mussel Mytilus edulis was studied. A suspension of algae Isochrysis galbana was added to the vessel with the mussels, and their filtration activity was measured by counting the concentration of the algae cells in the experimental vessels. Algae concentration was measured every 30 min for an hour and a half. The inhibiting effect on the mollusk filtration rate (FR) was qualitatively described. After the first 30 min filtration at 4 mg/l initial SDS concentration, the cell density was 322% of the control. The inhibiting effect was observed later as well. Due to FR inhibition in the vessels with the above specified initial SDS concentration, the algae cell density was 6.4 and 14.7 times that of the control after 1 and 1.5 h, respectively. Thus, SDS can decrease the natural capacity of aquatic ecosystems for self-purification and disturb other aspects of ecosystem functioning through inhibiting the filtration activity of mussels. The obtained data are discussed in the context of environment and hydrosphere protection from pollution. [MAIK Nauka/Interperiodica distributed by Springer Science+Business Media LLC.

Bibliogr. 71 refs. [Top-down control is an important type of interspecies interactions in food webs. It is especially important for aquatic ecosystems. Phytoplankton grazers contribute to the top-down control of phytoplankton populations. This article is focused on the role of benthic suspension-feeders (filter - feeders) in the control of plankton populations as a result of water filtering and the removal of suspended matter (including the cells of plankton) from the water column. New data on the inhibitory effects of synthetic surfactants and detergents on the activity of benthic filter-feeders (freshwater mussels Unio tumidus, U. pictorum, marine mussels Mytilus galloprovincialis, M. edulis, and oysters Crassostrea gigas) are presented and discussed. Importance and efficiency of that approach to the problems of eutrophication and water self-purification is pointed out. The chemical pollution may pose a threat to the natural top-down control of phytoplankton and water self-purification processes. The latter are an important prerequisite for sustainable use of aquatic resources. Surfactant SDS at a concentration of 0.5 mg/L inhibited water filtration by Crassostrea gigas, at a concentration of 1.7 mg/L suppressed the filtering activity of  M. galloprovincialis, at that of 1-5 mg/L decreased water filtration by M. edulis. The non-ionic surfactant Triton X-100 (TX100) at a concentration of 0.5-5 mg/L induced a sharp slowdown in water filtration by M. edulis, at 1 and 5 mg/L it caused a decrease in the filtration rate by  the freshwater bivalve Unio tumidus. The cationic surfactant TDTMA at 1-2 mg/L constrained the filtering activity of  the freshwater bivalve Unio pictorum. 4 detergents (6.7-50 mg/L) hindered the filtration by M. galloprovincialis. 3 detergents (1-30 mg/L) slowed down the clearance rate during water filtration by Crassostrea gigas. The shampoo AHC (Avon Herbal Care) at  concentrations 5-60 mg/L arrested the filtration by M. galloprovincialis]. (Springer Press, Dordrecht) ISSN 0018-8158. DOI 10.1023/A:1015559123646.

[Selected elements of a new vision of the role of biodiversity in water purification and maintaining the natural purification potential of ecosystems, elements of the theory of water self-purification. Some fundamental principles that characterize the pivotal roles of the biodiversity of filter-feeders in ecosystems. Among those roles are: (1) the role of ecological repair of water quality, (2) the role of contributing to reliability and stability of the functioning of the ecosystem, (3) the role of contributing to creation of habitat heterogeneity, (4) the role of contributing to acceleration of migration of chemical elements. It is an important feature of the biomachinery of filter-feeders that it removes from water various particles of a very broad range of sizes. Another important principle is that the amount of the organic matter filtered out of water is larger than the amount assimilated so that a significant part of the removed material serves no useful function to the organism of the filter-feeder, but serves a beneficial function to some other species and to the ecosystem as a whole. The author demonstrated a vulnerability of the filtration activity of filter feeders (e.g., bivalves and rotifers) to some xenobiotics (tetradecyltrymethylammonium bromide, heavy metals and some others).

Effects of several 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 oysters (Crassostrea gigas). Similar effects were exhibited by some chemical mixtures that included surfactants. Those mixtures inhibited the filtering activity of Crassostrea gigas and Mytilus galloprovincialis. The inhibition of filtering activity took place as a result of the effects of surfactant TDTMA 0.5mg l-1 on oysters Crassostrea gigas; SDS 0.5 mg l-1 on C. gigas; 3 synthetic detergent mixtures on  Mytilus  galloprovincialis and C. gigas. 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 Mytilus edulis (e.g., Ostroumov, 2000, 2001). This experimental approach is helpful in assessment of environmental hazards from man-made chemicals that can contaminate marine systems. DOI 10.1023/A:1024604904065.

Suspension-feeders are found in both pelagic and benthic systems. They function as an important part of an ecosystem's biomachinery that maintains water quality and purification potential in aquatic systems. They remove suspended matter and excrete faeces, pseudofaeces and dissolved inorganic materials that contribute to nutrient cycling between the water column and the benthic habitats. Suspension-feeders are a key part of many natural aquatic remediation systems and they can decrease some negative anthropogenic impacts.

Daphnia were kept under laboratory conditions in vessels and fed with phytoplankton: green algae Scenedesmus quadricauda (Turp.) Breb.). After filtration for 6–24 h in the presence of SDS at concentrations 5 and 10 mg/l, the abundance of S. quadricauda  cells in water was higher than in the control. At the lower SDS concentrations (0.1, 0.5, and 1 mg/l), differences in the abundance of algal cells relative to the control were observed after 3 h of incubation and disappeared after 6–24 h of incubation. The calculation of the mean rate of algae removal by daphnia  showed that this parameter decreased within the first 3 h after the beginning of incubation in the presence of SDS. Thus, SDS decreases the rate of water filtration by the planktonic crustaceans D. magna.

It was discovered that plant biomass help towards restoration the water quality in the system which was polluted with a synthetic surfactant.  Addition of sodium dodecylsulphate (SDS) to water rapidly changed the surface tension of water in the microcosm. The measurements demonstrated that the surface tension of water in the microcosm with the  macrophyte OST1 restored to the level which was close to that of pure water within less than three days. As soon as after 46-h incubation of the system containing the plant phytomass, the surface tension increased significantly and reached that of distilled water. In the variants with water without plant phytomass, restoration of the normal surface tension was much longer (about 17 days). The results demonstrated an accelerated restoration of the normal surface tension which was typical of pure water in those systems that contained SDS in the presence of the phytomass of the  macrophyte OST1. The conclusion: the macrophyte accelerates the  disappearance of the surfactant from water.
