WebFOCUS Report
Project description
The project focused on ecological and health risks of mining effluents with metals and on risk perception of local people. Biotic ligand models were utilized to simulate the bioavailable fraction of metals in surface waters and hydrological VEMALA-model the transport of metals downstream the mining sites. The selection pressure caused by the mining effluents has resulted in the enrichment of bacterial taxa capable of utilizing various chemical contaminants. In the laboratory toxicity tests L. variegatus responded to mining-affected sediments. Chemical risks for human health were evaluated based on lake water and fish. The focus was in mercury, and sulfate and manganese, which were found in high levels in surface waters, thus creating potential human health risk. High concentrations of chemicals in lake water can cause limitations of water use. Surface waters are not recommended for human consumption as drinking water in any case; therefore, health risks due to contamination remain low.
