Presentation transcript:

Impact of Acid Deposition

Acidifies fresh water bodies and soil Can not support life pH has been recorded as low as 2

Acidified lakes Uncharacteristically clear Contain no life No fish No algae

Acidified water Will mobilize metals Leaching Increasing the TDS (total dissolved solids) Occurs as polluted water flows over geological formation and the metals become part of the water’s ionic load

Toxic Heavy Metals Cyanide Mercury Lead Uranium None are biodegradable and therefore will bioaccumulate once they get into the food chain

Erosion As plants die, soil is exposed to wind and rain
