Abstract
| To understand the mechanisms of the impact of external pollution on the state of lake ecosystems a comprehensive analysis of matter fluxes in Lake Matsimäe is presented. To study the biogeochemical cycling and deposition processes in the lake the atmospheric flux was estimated with Tauber traps, and sediment traps were used to collect sinking and recycling matter in the water. In addition, uppermost samples in sediment core were analysed. The amount and composition of dry matter, pollen and spherical fly-ash particles produced by combustion of fossil fuel were used as indicators. The obtained data show that redeposition in the deep and flat area is modest in L. Matsimäe. Geochemical and palaeobiological records allow reconstruction of the trends in the environmental conditions with resolution not less than 2–3 years. |
