TAILIEUCHUNG - Biological effects of surfactants - Chapter 7 (end)

7 Biological Effects of Synthetic Surfactants and Participation of Hydrobionts in Water Purification Experience indicates the negative impacts of surfactants and surfactant-containing preparations on representatives of the major functional ecosystemic blocks, including both autotrophic and heterotrophic organisms (see above). The author realizes that interpretation of the results obtained requires great caution and there are many factors that can affect the manifestation of biological effects of synthetic surfactants in more complex systems. Therefore, direct transfer of the laboratory results to natural ecosystems is inappropriate. The need for caution in interpreting experimental results was emphasized by .

Flerov 1989 and other investigators when they analyzed the problems of using the results of laboratory experiments for understanding the situation in ecosystems under conditions of anthropogenic pollution. It seems interesting to discuss the results obtained touching upon important issues related to the functioning of ecosystems in conditions of anthropogenic impacts 1 issues of self-purification of aquatic systems 2 some applied problems related to self-purification of water 3 problems of assessing the potential ecological hazard of anthropogenic impact on aquatic biota. Self-Purification of Water and the Role of Hydrobionts in Aquatic Ecosystems There are several definitions for self-purification of water in scientific literature. According to one of the definitions self-purification is the entire complex of biological physical and chemical processes that determine the ability of water bodies to get rid of pollution introduced by sewage waters and formed due to the vital 2006 by Taylor Francis Group LLC 182 .
