Impacts of Mining Practice Test

Lower turbidity increases photosynthesis, leading to algal blooms driven primarily by nitrogen fixation from exposed bedrock surfaces.

Reduced salinity drives osmoregulatory stress in freshwater fish, but metals remain insoluble and therefore biologically unavailable in most conditions.

Higher pH causes carbonate precipitation, removing metals and improving downstream water clarity and fish reproduction within one season of operation.

Increased dissolved metals mobilize, harming aquatic organisms and reducing biodiversity through acid mine drainage and associated toxicity in downstream waters.
