The study was conducted to analyze copper (Cu) bioaccumulation in water, sediments and in different tissues of common carp, (Cyprinus carpio), like muscles, Intestine, skin, liver and gills collected from Kalpani stream Mardan. The results recorded for bioaccumulation of copper was like that, in water samples the mean value for copper concentration was 0.014ppm; in sediment samples mean value for copper concentration was 0.47ppm. Similarly the mean value for copper concentration in Muscle tissue was 0.003ppm; in Intestine tissue was 0.10ppm; in Skin tissue was 0.06ppm; in Liver tissue was 0.03ppm and in Gills tissue was 0.07ppm. Our finding shows that copper concentration on the basis of mean values was high in sediment samples, which is then followed by intestine tissue, gills tissue, skin tissue, liver tissue, water samples and finally muscle tissue. It can be shown as Sediments>Intestine>Gills>Skin>Liver>Water>Muscle. So it’s concluded that Copper show more affinity towards Sediments and least affinity toward muscle tissue. When we compare copper concentration in water and sediments so concentration is more in sediments samples as compared to water samples. Copper concentration in the three media was in the order of Sediments>Fish>Water.
