Imbalance of Factors Providing Control of Unicellular Plankton Populations Exposed to Anthropogenic Impact

Journal: Doklady Biological Sciences , vol. 379, no. 1, pp. 341-343, 2001
 The first discovery of how negative effects of pollutants (surfactants) on invertebrate animals (filter-feeders) may lead to a change (increase) in abundance of plankton organisms in water; the first data on how the effects of polluting chemicals on invertebrate animals (filter-feeders) may produce an imbalance in the set of the factors controlling the populations of plankton.

  • Ostroumov S.A. Imbalance of factors providing control of unicellular plankton populations exposed to anthropogenic impact. – Doklady Biological Sciences, 2001. Vol. 379, P. 341-343. 4 tables. Bibliogr.12 refs. (Translated from DAN 2001. Vol. 379. P.136-138). ISSN 0012-4966 (Print) 1608-3105 (Online). PMID: 12918370 [PubMed – indexed for MEDLINE]. The paper presents and analyzes new experimental data on the effects of chemical pollution of aquatic medium on the abundance of unicellular plankton organisms. The following 6 types of effects of filter-feeders and chemical pollutants [surfactants and detergents (mixtures)] on phytoplankton organisms were found (examples were given in this paper in Tab.2): (1) Inhibition of growth (and abundance); (2) Growth stimulation in the presence of surfactants and detergents; (3) Decrease in abundance as a result of elimination of plankton cells from water by the freshwater mollusks Unio tumidus and rotifers; (4) Abundance decrease as a result of water filtration by the marine mollusks Mytilus edulis, M. galloprovincialis, and Crassostrea gigas; (5) Decrease in the efficiency of cell elimination from water caused by the TX-100-induced (5 mg/l) inhibition of the filtration activity of the freshwater mollusks U. tumidus; (6) Decrease in the efficiency of cell elimination from water as a result of inhibition of the filtration activity of the marine mollusks Mytilus galloprovincialis and Crassostrea gigas induced by surfactants and Avon Herbal Care (hair shampoo). A new parameter and formula is suggested: the efficiency of cell elimination from water, ECE. The following maximum values of ECE were found (at the concentrations of the chemical, mg/l, in brackets): (1) Detergent OMO, Unio tumidus, 186.7 (50); (2) Detergent Losk-Universal, Mytilus galloprovincialis, 551.7 (7); (3) Detergent Tide-Lemon, Mytilus galloprovincialis, 206.9 (50); (4) Detergent IXI, M. galloprovincialis, 157.8 (10); (5) Detergent Deni-Automat, Crassostrea gigas, 10 800.0 (30); (6) Detergent Lanza, Crassostrea gigas, 261.7 (20); (7) Detergent Vesna-Delikat, Crassostrea gigas, 200.0 (1); The tables in the paper: Factors of regulation of unicellular plankton abundance (Tab.1); effects of surfactants and detergents on phytoplankton abundance (Tab.2); 7 detergents inhibit filtration of 3 species of marine and freshwater molluscs (Tab.3); Mytilus galloprovincialis eliminates from water the cells of Saccharomyces cerevisiae and algae Pavlova lutheri = M. lutheri as a result of filtration (comparing the 2 processes at the same time, Tab. 4). The results obtained in this work demonstrated and proved that certain pollutants might cause a substantial imbalance of the factors controlling unicellular plankton populations. Direct and indirect (mediated by organisms-consumers) effects of certain surfactant-containing mixtures on unicellular plankton could sum with each other, giving rise to mutual amplification. This may cause a complete imbalance of the system. The conclusions made in this work may be applied to unicellular plankton of both marine and freshwater ecosystems, including ecosystems subjected to eutrophication. The results contribute to issues of environmental safety and resource use sustainability. DOI 10.1023/A:1011600213221;
