    Due to the environmental pollution is serious, water, water content, lead to increase of mercury in fish live in water of the shellfish, by mercury pollution. Mercury in nature, is not easy to degrade the river or seawater in the plankton into methyl mercury and through the food chain from a lower to a higher biological creatures relay.

    In 2009, the United States geological survey for American 300 rivers of the fish in the investigation, found that every fish samples all contain mercury, about a quarter of the mercury levels in fish more than the epa make safety standards.

    Although now governments are taking measures to improve the environment pollution, but, because of the mercury is not easy to degrade sex, eliminate the mercury in industrial pollution, fish pollution will last 15 years or longer. Therefore, people eat methyl mercury pollution after the aquatic products, fat soluble methyl mercury can smoothly through the blood brain barrier into the brain cells, cause nerve damage.

    Mild mercury poisoning symptoms nonspecific, such as fatigue, memory deficits, insomnia and even personality change, joint pain, generally not easy to cause the people to value, few have checked to the hospital. But long-term consumption of aquatic products, by mercury pollution mercury easy accumulation in the human body, will lead to chronic mercury poisoning. The pregnant woman eat too much food of mercury pollution, methyl mercury can through the placenta to the fetus and the baby produce harmful effects, after the baby was born can appear mental retardation and slow growth, immune function low and so on.

    In order to reduce the chance of mercury poisoning, people should try to eat the fish short growth cycle, because life long fish body is more likely to contain methyl mercury. To prevent the mercury poisoning caused by eating aquatic products, people should try to eat animals ZhongDiJi chain of creatures, and try not to long-term excessive edible aquatic products.
