How does acid deposition impact aquatic environments?

Fish do not often die, but they do become too full of toxins to be consumed by humans.

Aquatic environments become temporarily lifeless while new species of fish who can tolerate the acid deposition replenish the stock.

Fish that absorb the chemicals either die, become sterile or produce mutated offspring, and are too full of mercury to eat.

Aquatic environments are not directly impacted by acid deposition.
