[citation needed] EPA estimated the economic cost at $9.6 billion annually. It is Japan's goal to promote international mercury legislation in hopes of preventing any country from experiencing what it did. Thats because its a great source of protein, micronutrients, and healthy fats. Mercury occurs in deposits throughout the world mostly as cinnabar (mercuric sulfide). Bag-based filters are also used in factories that may contribute mercury to the environment. Fish efficiently absorb methyl mercury, but excrete it very slowly. [11] The largest source of mercury contamination in the United States is coal-fueled power plant emissions.

The effects of these different sources of mercury have been studied at the Experimental Lakes Area in Ontario, Canada, using research procedures including whole-lake ecosystem experiments and non-lethal fish muscle biopsies.[8]. [45] The George W. Bush administration intended for the regulation to use a cap-and-trade system to control emissions across multiple industries. It eats mainly aquatic plants, including filamentous algae and diatoms, but it consumes the occasional mollusk and other animal matter. Indiscriminate dredging of the lake bottom for lime shell deposits has turned catastrophic for the natural breeding of the fish. Nangu - Sole Fish. EPA subsequently classified mercury emissions from power plants as hazardous under section 112 of the Clean Air Act. The acceptable level of mercury is mentioned, which can determine how much of the fish type may be consumed, based on mercury levels: Least mercury: Less than 0.09 parts per million Moderate mercury: From 0.09 to 0.29 parts per million High mercury: From 0.3 to 0.49 parts per million Highest mercury: More than 0.5 parts per million Both total mercury and methyl mercury absorption was found to be derived from sediments containing mercury, not mainly from fish feed.[3]. Rich sources of complete protein, seafood supplies all the amino acids your body needs to build and repair tissue. Mercury pollution can also be removed by electrostatic precipitators (ESPs). A very popular freshwater fish in Kerala is the delicate flavored pearl spot fish which is common to the lakes and backwaters. Cite This Page (APA): Disabled World. [11] Production of the species for food is expected to increase in the near future.[5]. A study by Jardine has found no reliable connection between mercury in fish food affecting aquaculture organisms or aquatic organisms in the wild. Eat up to 2 meals per week of fish from the LOW in mercury list. In Canada, the limit for the total of mercury content is 0.5 ppm.

Over time, methylmercury the organic form can concentrate in their bodies. However, they are absorbed, usually as methyl mercury, by algae at the start of the food chain. 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. Chief among these efforts was the reduction of inorganic mercury produced by mines. Mercury is in the air, water, and soil of the planet. For example, herring contains mercury levels at about 0.1 parts per million, while shark contains mercury levels greater than 1 part per million. As its not easily excreted from their bodies, levels accumulate over time. Mercury-containing plants and tiny animals are eaten by smaller fish that are then eaten by larger fish, whose tissue accumulates mercury.
