A recent study conducted in Korea has shed light on the distribution of heavy metals in various organs of eleven shrimp species commonly found in the region. The assessment covered lead, cadmium, total arsenic, arsenite, arsenate, monomethyl arsenic acid, dimethylarsinic acid, total mercury, and methylmercury levels in six organs of shrimp.

Among the organs analyzed, the intestine stood out with the highest overall metal content. Cadmium was found to be most prominent in the head, while total mercury showed the highest concentration in the muscle.

Despite the variations observed, the Hazard Quotient values of the analyzed shrimp species remained below the allowable limits set by the European Food Safety Authority for heavy metals. This suggests that the levels of heavy metal contamination in Korean shrimp are within safe limits for consumer consumption.
