Selecting fish As part of a healthy diet, everyone is encouraged to eat two to three serves of fish per week. Additionally, some studies suggest that certain ethnic groups including Native Americans, Asians, and Pacific Islanders have a greater risk of mercury exposure due to diets traditionally high in fish (29). The 2012 Mercury and Air Toxics Standards (MATS) regulation, issued by the Barack Obama administration, targets airborne mercury emissions from power plants and other stationary sources. [53] The next step was the Stockholm Declaration, which urged countries to avoid polluting the oceans by dumping. 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. 25% of the fish tested had mercury levels above the safety levels determined by the U.S. Environmental Protection Agency for people who eat the fish regularly. When it comes to fish, there is much debate on whether the benefits outweigh potential safety concerns. Since the Minamata disaster, Japan has improved on its mercury regulation. Indiscriminate dredging of the lake bottom for lime shell deposits has turned catastrophic for the natural breeding of the fish. Mercury can cause both chronic and acute poisoning.

This element is known to bioaccumulate in humans, so bioaccumulation in seafood carries over into human populations, where it can result in mercury poisoning. When addressing the issue of reducing seafood mercury bioaccumulation on a global scale, it is important to pinpoint major energy producers and consumers whose exchange of energy may be the root of the problem. However, sea plants like algae absorb it. [11] Production of the species for food is expected to increase in the near future.[5].

Mercury can be absorbed through the skin and mucous membranes and mercury vapors can be inhaled, so containers of mercury are securely sealed to avoid spills and evaporation. Interestingly, seawater contains only small concentrations of methylmercury. Mercury is a dangerous neurotoxin that can disrupt brain function and harm the nervous system. It can collect in streams, lakes, and oceans and is. Regulation of these potential sources of pollution reduces the amount of mercury that ends up in fish and, through biomagnification, in humans. One study from 1998 to 2005 found that 27% of fish from 291 streams around the United States contained more than the recommended limit (2). Fish and shellfish that contain higher levels of these fatty acids and are also low in mercury include: anchovy, capelin, char, hake, herring, Atlantic mackerel, mullet, pollock ( Boston bluefish), salmon, smelt, rainbow trout, lake whitefish, blue crab, shrimp, clam, mussel and oyster. 11(3), p.1800, EPA (2012-02-16).

Anthropogenic sources are responsible for 30% of all emissions, while natural sources are responsible for 10%, and re-emission accounts for the other 60%. The concentrations of Hg in swordfish, Atlantic bluefin tuna and red mullet accounted for 50%, 30% and 30% of the MLs, respectively. Substances poisonous to the human body in a particular amount or dose may not cause any symptoms over time. [4] Cetaceans (whales and dolphins) also bioaccumulate mercury and other pollutants, so populations which eat whale meat, such as the Japanese, Icelanders, Norwegians and the Faroese, are also vulnerable to mercury ingestion. Most of this mercury pollution can be eliminated if pollution-control devices are installed. [31], Certain countries have cultural differences that lead to more fish consumption and therefore more possible exposure to seafood methylmercury. That is why larger, longer-living predators such as sharks and swordfish tend to have more of the toxin than smaller fish such as sardines, sole, and trout. Avoid higher-mercury fish, such as tilefish from the Gulf of Mexico, shark, swordfish, and king mackerel.

[1][2], In human-controlled ecosystems of fish, usually done for market production of wanted seafood species, mercury clearly rises through the food chain via fish consuming small plankton, as well as through non-food sources such as underwater sediment.[3]. Mercury is an element that occurs naturally in the environment and is also released to the environment through many types of human activity. She will be able to tell you if the degree of mercury exposure is a concern, and what to do about it.
