Abstract: The purpose of this work is to compare the amounts of eight bioaccumulated metal elements in the gills, muscle, liver and gonads of a fish, Lepomis gibbosus Linnaeus, 1758. The individuals analyzed are taken from a living population in the "fouarate" lake which is located in the urban area of ​​the city of Kenitra (Morocco).
The estimation of the concentration of eight metal elements (Fe, Pb, Cd, Cu, Zn, Ni, Mn, Cr) was carried out by atomic absorption in each of the organs. The analyzed sample consisted of three subsamples of different sizes.
The results showed that the importance of the concentration of metal elements differs according to the metal element itself, the organ and the size, otherwise the age, of the fish. In addition, among the eight studied metals, four of them are very common in the organs of the studied fish: zinc, manganese, nickel and copper. The order of the decreasing ranking of the concentrations of the studied metals differs according to the size of the fish, in other words, according to their age. But in older fish, almost always zinc takes first place.
