Biological chemical reaction that negatively affects life
Answer:
Biological effects of mine drainage on the aquatic ecosystem range from severe effects that kill most macroinvertebrates and fish to improvements of the water quality when unpolluted mining influenced water drains into a polluted water course. These effects can result from large mining operations, mining accidents or by artisanal mining . Effects on fish can vary depending on the animal's age: whilst juvenile fish might avoid mine water influenced streams, adults might be able to survive in the elevated pollutant concentrations. Ecosystem management programs need to be site specific, taking into consideration the high variability of geological and climatic conditions.
