Inhibition of mussel suspension feeding by surfactants of three classes.
In short:
The first paper that reports experiments that showed that all three main kinds of synthetic surfactants (detergent chemicals) slow down the filtration of water by marine organisms, filter-feeders (bivalve mussels of Atlantic Ocean, Latin name Mytilus edulis). The 3 main types of surfactants that were studied were representatives of the 3 classes: anionic, cationic, and non-ionic surfactants. The word ‘Surfactants’ means the same as ‘surface-active substances’ and ‘surface-active agents’.

ABSTRACT: For the first time the negative effects of SDS, TDTMA, and Triton X-100 on Mytilus edulis and M. edulis / M. galloprovincialis - effects of the three surfactants - on the filtration rates by marine mussels were presented in one paper. The xenobiotics tested represented anionic, cationic and non-ionic surfactants (tetradecyltrimethylammonium bromide, TDTMA, a representative of a class of cationic surfactants; sodium dodecyl sulphate, SDS, a representative of anionic alkyl sulfates; and Triton X-100, a representative of non-ionic hydroxyethylated alkyl phenols). Negative effects of SDS, TDTMA, and Triton X-100 on the filtration activity of marine mussels M. edulis and M. edulis / M. galloprovincialis were discovered. All three surfactants inhibited the clearance rates. This is the first publication of the negative effects of a cationic surfactant on Atlantic mussels Mytilus. The significance of the results for the ecology of marine ecosystems is discussed.

IMPORTANCE: 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 another paper that adds to the discovery made by Dr. S. Ostroumov - 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.

On the concepts of biochemical ecology and hydrobiology: Ecological chemomediators

The paper explained the new scientific terms (ecological chemomediators, ecological chemoregulators) that were coined in 1986 in the book S.A.Ostroumov ‘Introduction to Biochemical Ecology’. Since 1986, the book and the new terminology became a part of educational content of a number of courses in universities of at least five countries.

The role of biodetritus in accumulation of elements in aquatic ecosystems
This paper is the first publication that reported the concentrations of a number of rare earth elements in biodetritus. The rare earth elements are a key component of modern hi-technology products and they are a new component in the modern solid wastes and waste waters. This paper is an innovative and significant contribution to the database for modern environmental monitoring.

ABSTRACT: Biodetritus that formed over a 7-month period in microcosms with Viviparus viviparus, Unio pictorum , and Ceratophyllum demersum contained a number of elements. This is the first study to determine concentrations of some elements in biodetritus. Neutron activation analysis showed that the elements’ concentrations decrease in the following order: Ca > Zn > Ba > Br > Ce > Se > Nd > La > U > Hf > Sb > Th > Sm > S > Cs > Au. The data obtained contribute to understanding of the polyfunctional role of aquatic organisms in aquatic ecosystems.
