Legislation on a global scale is believed by some to be needed for this issue because mercury pollution is estimated to be so far-reaching. [18] The College argues that the omega-3 polyunsaturated fatty acids found in fish have a health benefit that outweighs the harm from mercury or polychlorinated biphenyls. Such mercury from gold mines is specifically known to contribute to biomagnification in aquatic food chains.[14]. Eating fish and shellfish is a major source of mercury exposure in humans and animals. On this Wikipedia the language links are at the top of the page across from the article title.

Species of fish that are long-lived and high on the food chain, such as marlin, tuna, shark, swordfish, king mackerel and tilefish contain higher concentrations of mercury than others. Mercury is known to bio-accumulate in humans, so bio-accumulation in seafood carries over into human populations, where it can result in mercury poisoning. Bag-based filters are also used in factories that may contribute mercury to the environment. Mercury is a naturally occurring heavy metal. The FDA characterizes shrimp, catfish, pollock, salmon, sardines, and canned light tuna as low-mercury seafood, although recent tests have indicated that up to 6 percent of canned light tuna may contain high levels.
