Heavy metal elements are more likely to accumulate in which parts of fish and shrimp

Deposits in the liver. In the animal body, the liver is the base camp of nutrient reserve, it contains A variety of vitamins needed by the human body, of which vitamin A, vitamin D, vitamin B2, vitamin B12 content is particularly high. Liver protein exceeds the content of lean pork, iron, zinc, copper, manganese and other trace elements are very rich, almost the most complete and most abundant food in nature. The liver is like a huge "chemical", food, water, etc. will be absorbed into the blood through digestion, and then transported by the blood to the liver for further catabolism. If animals drink unclean water, or overuse certain drugs, heavy metals and other pollutants, it will be deposited in the liver. The pollution hazards of heavy metal elements: 1, especially the damage to the cells, organs, skin, bones and nerves of the digestive system and urinary system. And heavy metal metabolism is difficult, once in the body precipitation will bring a lot of harm to the body. 2, heavy metals in natural concentrations widely exist in nature, but due to the increasing human mining, smelting, processing and commercial manufacturing activities of heavy metals, resulting in many heavy metals such as lead, mercury, cadmium, cobalt, etc. into the atmosphere, water, soil, causing serious environmental pollution. 3, in a variety of chemical states or chemical forms of heavy metals, after entering the environment or ecosystem will remain, accumulation and migration, causing harm. For example, heavy metals discharged with wastewater, even if the concentration is small, can accumulate in algae and sediment, and be adsorbed by the body surface of fish and shellfish, resulting in concentration of the food chain, thereby causing public hazards.
