It can move throughout your body, where it can penetrate cells in any tissue or organ. Knowing how easily and how often previously emitted mercury can be released helps us learn how long it will take for a reduction in anthropogenic sources to be reflected in the environment. 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. Mercury occurs in deposits throughout the world mostly as cinnabar (mercuric sulfide).

It is an indigenous fish extensively found along the east and south-west coasts of Peninsular India. Thus, bighead carp gather more mercury by eating large amounts of small plankton, as well as sucking up sediments that collect a sizable amount of methyl mercury. While it is difficult to estimate the exact extent of mercury re-emission, it is an important field of study. Froese, Rainer; Pauly, Daniel (eds.) Mercury is a naturally occurring element found in soil, water, and air. Recent studies also link exposure to heavy metals such as mercury to conditions like Alzheimers, Parkinsons, autism, depression, and anxiety (18). Children exposed to mercury are particularly susceptible to poisoning since the ratio of food, water, and air intake versus individual body weight is much higher than that of adults. It's a metal that turns to liquid at room temperature, and over time, can slowly accumulate in the bodies of humans, fish, and other animals that eat fish.

Karimeen, the state fish of Kerala Karimeen which is also known as Pearl spot fish is one of the most important fish species in Kerala. Exposure to mercury can cause serious health problems (16). [13] In other countries, such as Ghana, gold mining requires mercury compounds, leading to workers receiving significant quantities of mercury while performing their jobs. [25] Over-the-counter medicines have been shown to have traces of mercurous chloride. Eat up to 2 meals per week of fish from the LOW in mercury list. Karimeen is rich in healthy fats such as omega 3 fatty acids, which keep the heart and brain healthy. Vol. [10], Anthropogenic sources include coal burning, cement production, oil refining, artisan and small-scale gold mining, wastes from consumer products, dental amalgam, the chlor-alkali industry, production of vinyl chloride, and the mining, smelting, and production of iron and other metals. Drinking hot water is a great way to stay hydrated, and it might have extra health benefits. The state fish is the Pearl spot, locally known as Karimeen in the family Cichlidae.

Minamata poisoning demonstrated that significant prenatal and postnatal exposure to high levels of methylmercury caused serious neurological problems. Mercury poisoning in Minamata, Japan, is now known as Minamata disease. [29] Additionally, children undergo fast growth that causes them to be more susceptible to damaging exposure to methylmercury, as well as the long term consequences of such exposure during childhood development. [12] Chlorine chemical plants use mercury to extract chlorine from salt, which in many parts of the world is discharged as mercury compounds in waste water, though this process has been largely replaced by the more economically viable membrane cell process, which does not use mercury. In fact, mercury exposure has been linked to serious health problems. Highest Hg levels were found in predatory fish. Larger fish tend to eat many smaller fish, which contain small amounts of mercury. 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]. Pearl Spot is rich in minerals such as calcium and phosphorus. In comments submitted to federal health officials, a group of scientists and policy analysts pointed out that a 6-ounce serving of salmon contains about 4 micrograms of mercury vs. 60 micrograms for the same portion of canned albacore tuna - and 170 micrograms for swordfish.
