Age-dependent heavy metal content in muscle tissue of brown bullhead (Ictalurus nebulosus, Le Suerur, 1819)

Abstract

We used brown bullheads (Ictalurus nebulosus) from Milicz Ponds in our study. The authors examined the impacts of age, body length, body weight, and the condition of the fish on concentrations of metals (Cd, Pb, Ni, Cu, and Zn) in their muscle tissue (n=62). The metal contents in muscle tissue increased in the order from Cd < Ni < Pb < Cu
