Abstract

The goal of this research is to determine the concentrations of heavy metals (Copper, Zinc, Lead, and Cadmium) in water and crayfish tissues (Gills, Muscles, and Exoskeleton) collected from three different sites at Fayoum governorate, Egypt. According to the data, the water quality of the three sites differed significantly in terms of physical and chemical properties. The bioaccumulation of lead and cadmium in crayfish muscles from the three sites show an increase in their concentrations. The nutritional value of crayfish meat samples decreased significantly as a result of the study's findings, and they were no longer fit for human consumption. As a result of water deterioration, the protein and fat content of the crayfish muscles, as well as the concentrations of calcium and phosphorus, all decreased significantly.
Keywords: Procambarus clarkii, Heavy metals bioaccumulation, Meat quality, human consumption, crayfish muscles.
