Abstract:
The first article to report negative effects of chemical pollutants on the organic matter transfer through ecological system. The ecological system was modelled by experimental microcosms. The organic matter transfer was exemplified by the organic matter transfer and chemical element transfer through a trophic chain. The key organism in this trophic chain was the aquatic mollusk, pond snail (Lymnaea stagnalis). In the author experiments, effects of the chemicals, synthetic surfactants, on the feedeing rate and pellet excretion rate, where discovered and studied. It was discovered that the synthetic surfactants decreased the transfer of the organic matter and a number of chemical elements through the trophic chain and ecosystem.
