An Amphiphilic Substance Inhibits the Mollusk Capacity to Filter out Phytoplankton Cells from Water
The effect of synthetic anionic surface active substance (SAS) 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, SAS 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.

- ABSTRACT. The article gave a fresh review and innovative analysis of the vital role of filter-feeders in functioning and maintenance of stability of aquatic ecosystems (both freshwater and marine ones). The paper includes the following tables which summarize many relevant facts and innovative ideas.
- Tables: Table 1. Examples of the impact of filter-feeders on the water column: clearance time. Table 2. Examples of diversity of taxa of benthic organisms involved in removing seston from water, and filtration rates. Table 3. Effect of the increase in concentration of algae on the filtration rate and the amount consumed by rotifers Brachionus calyciflorus. Table 4. The ratio F:P in some groups of organisms (examples of what the author named “ecological taxation”, the new concept and term coined by the author). Table 5. The ratio F: (P+R) in some filter feeders. Table 6. Results of the ecological tax: biosediment formation in 6 ecosystems. Table 7. Contribution of various aquatic organisms to oxidation of organic matter in the ecosystem of the Sea of Okhotsk. Table 8. Some chemicals that inhibit the filtering activity of the filter-feeders (new data of the author). Table 9. Some features of water-filtering biomachinery: 6 fundamental principles. Table 10. The level-block approach to the analysis of ecological hazards of anthropogenic effects on the biota (the new conceptualization proposed by the author).
- 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 (a new concept and term proposed by the author) 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 suspended 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 new experiments by the author additionally demonstrated a vulnerability of the filtration activity of filter feeders (e.g. bivalves and rotifers) to some chemical pollutants and xenobiotics (e.g., synthetic surfactants exemplified by tetradecyltrymethylammonium bromide, and also heavy metals and some others). The inhibition of the filtration activity of filter-feeders may lead to the situation previously described as that of an ecological hazard of the second type.

The consumed materials that aren’t assimilated, however, are not lost from the food web to respiration or burial. Instead, they are deposited on surface sediments in the form of feces or pseudofeces (Strayer et al., 1999). Thus, part of what mussels ingest is not of direct use to them but can reenter the ecosystem (Ostroumov, 2005). Both 5 suspension feeders and deposit feeders benefit from this cycling of matter (Howard & Cuffey, 2006). The excretory waste products of mussels, or “biodeposits”, are..
