However, more studies are needed to confirm this link. IV: An Assessment of Exposure to Mercury in the United States . Regulation of these potential sources of pollution reduces the amount of mercury that ends up in fish and, through biomagnification, in humans. Mercury is a natural part of the Earth's environment and its presence is increased by human activity.

Another study discovered that one-third of fish caught on the New Jersey shore had mercury levels higher than 0.5 parts per million (ppm) a level that could cause health problems for people who eat this fish regularly (3). Anything that eats these fish within the food chain also consumes the higher level of mercury that the fish have accumulated, including humans.
