Lead: shrimp intestines> shrimp shell> shrimp head> shrimp yellow> shrimp tail meat

Cadmium: shrimp yellow> shrimp head> shrimp intestine> shrimp shell >Shrimp Tail Meat

Chromium: Shrimp Intestines>Shrimp Shells>Shrimp Heads>Shrimp Yellow>Shrimp Tails

The experimenter said that there are two ways of heavy metal pollution in aquatic products. One is exogenous pollution, which refers to the environment in which aquatic products live ; One is endogenous pollution, which is its own concentration and enrichment of heavy metals. As an industry, crayfish has been standardized and cultivated. Artificially cultivated lobsters have a controllable environment and controllable heavy metal concentration. The concentration of heavy metals is greatly reduced. The wild ones will be at ease.

So be sure to buy crayfish from artificial legal farms. Generally, crayfish raised in clean water have relatively low heavy metal content. Don’t buy crayfish from unknown sources just for the sake of cheap. Potential harm.
