- The sedimentological, geochemical and diatomological research into the core taken from the fossil lake located in the glacial channel of Samica river prove the increasing anthropogenization of the landscape in the microregion surrounding the settlement in Bruszczewo. Anthropogenic indices of the Early Bronze Period in the palynological research include: high decline in the percentage of tree pollens caused by deforestation, indicators of grazing animals and farming as well as noticeable eutrophication of the lake (fungal spores and algae thriving on dung, droppings and excrement). In the sedimentological research, cultural layers correspond with accelerated mineral sedimentation in the basin (mediumand fine-grained sands). Each time it is preceded with organic sedimentation (from humus levels). Above results might signify the initiation of erosion-denudation processes in the catchment, settled and economically exploited by individual cultural groups. Results of the anthropogenic activity are visible also in the geochemical composition of the deposits. Cultural layers are marked with increased percentage of heavy metals, while the Cu : Pb : Zn ratios suggest their anthropogenic character. Additionally, the increase in phosphorus percentage confirms eutrophication of the basin in the settlement periods, that is in the Early and Late Bronze, and Early and Roman Iron Ages.
