Mercury itself exists in nature, but the level is not so high.Due to industrial production, a large amount of gaseous mercury has been generated by the process of coal -fired power generation, melting, and waste incineration.The mercury is dissolved in the soil and rivers and lakes, absorbed by the biology in the water, and collects along the food chain in the organism.
All fish and seafood contain heavy metal mercury to varying degrees, and some species also contain some persistent organic pollutants.According to the natural laws of eating small fish and small fish, large -scale hunting deep sea fish located on the top of the food chain will inevitably enrich the high degree of mercury and other pollutants.These aquatic organisms can not be reduced through the cooking process. Therefore, the only way to reduce mercury intake is to avoid large -scale fish with high mercury -containing mercury.
The US Food and Drug Administration (FDA) has always suggested that women, pregnant women, lactating women and young children who are preparing to prepare pregnant women to avoid eating some fish, such as sharks, and choose fish and seafood with lower mercury content.In the old guide, it is also recommended to restrict the number of fish eating, not more than twice a week.
