Effects of acids and alkalis on aquatic life

Limestone can buffer (neutralize) the acidification of freshwater. The effects of acid deposition are much greater on lakes with little buffering capacity. Much of the damage to aquatic life in sensitive areas with this little buffering capacity is a result of ''acid shock''. This is caused by the sudden runoff of large amounts of highly ...
