The role of freshwater mollusks Lymnaea stagnalis in the flows of chemical elements in the biosphere was studied by detecting the elemental composition and amount of pellets produced by the mollusks. For the first time, the following was quantitatively studied: the elemental composition (C, N, P, Si, Al) of pellets formed by mollusks Lymnaea stagnalis feeding on the leaves of higher plants Nuphar lutea and Taraxacum officinale; the amount (wet weight, dry weight) of pellets formed by L. stagnalis feeding on the leaves of N. lutea and T. officinale; the transfer of matter and chemical elements (C, N, P, Si, Al) with pellets of freshwater bivalves (unionids Unio sp., etc.) per unit biomass of mollusks and per unit area of the ecosystem of the river; the transfer of matter and chemical elements (C, N, P, Si, Al) with pellets of L. stagnalis per unit biomass of mollusks and per unit area of the ecosystem of the pond. Synthetic surfactants ТDТМА 2 mg/l, SDS 1-2 mg/l, detergent Tide-Lemon 75 mg/l inhibited the trophic activity of L. stagnalis.
