As can be seen by comparing the data of Tables 2 and 3, the content of trace elements in salmon muscle is significantly lower than in the entire carcass. It is two times lower for mercury, which is found primarily in adipose tissue; about one and a half times lower for lead, which is concentrated mainly in the bones of fish; two times lower for cadmium, which accumulates mainly in the liver; and almost two times lower for zinc, which primary sedimentates in the gills and the gonads. Only the concentrations of the copper and arsenic remain the same both in the entire carcass and the muscles.
