Correct me if I'm wrong, but I thought acid rain is more of a contributor of carcinogenics than of mercury.
Isn't mercury pollution more the result of our own logging industry and CURRENT polluting of our own rivers and streams?
Sadly, it affects both fresh and salt water inhabitants eqaully.
The larger the predator, the more mercury they absorb from their prey, their prey's prey and their prey's prey's prey etc......
Whether it's acid rain or mercury pollution, we all lose in the end!!!
