Mercury Mercury is the second smallest planet in the solar system, the nearest and innermost planet to the sun. Do you know that the sun is warming Mercury? Mercury is a distance of 36 million miles from the sun and takes 88 days to avoid it. But Mercury has no gas. The mercury surface is very hot at temperatures ranging from 430 ° C to 130 ° C. Mercury is based on a lot of history; Mercury can be seen with the telescope and the naked eye.

Mercury has three forms: (1) elemental mercury, (2) inorganic salt, and (3) organic compound. Perhaps the most deadly form of mercury is methylmercury. Only 2-10% of the ingested mercury is absorbed from the intestine and no elemental mercury ingested is absorbed at all, but 90% of the ingested methylmercury is absorbed by the bloodstream from the gastrointestinal tract. Organic mercury compounds, especially methyl mercury, are concentrated in the food chain. Fish from contaminated water is the most common cause. Industrial mercury contamination is usually an inorganic matter, but vegetation in waterways such as aquatic organisms, rivers, lakes and bays converts it to fatal methyl mercury. Fish eat polluted vegetation, mercury in fish is bioaccumulated. More than 90% of fish protein is consumed by methylmercury. And it is not removed even by the most intense cooking methods (eg fried, boiled, roasted, fried). (See etiology)

In water, small organisms convert inorganic mercury to organic mercury methyl mercury. Methylmercury is incorporated into the aquatic food chain by combining it with granules and sediments consumed by fish. Large fish may predispose fish contaminated with small mercury, which generally results in the amount of mercury stored in the captured fish. The fish removes mercury at a very slow rate; therefore, mercury tends to accumulate in its tissues and organs. Directly to the fetus. Because of the well documented effect of mercury on the nervous system and due to the high susceptibility of the developing fetus, the West Virginia Public Health Bureau is pregnant women, women of childbearing age, lactating mothers and children We encourage you to follow West Virginia Sportsfish Advisory Advice and EPA. And to encourage the FDA to buy fish for restaurants and food items. Recommendations of EPA and UFDA are as follows.
