Detection of the accumulation of heavy metals in Oreochromis niloticus fish flesh collected from three different Sudanese dams

Abstract

The present study aimed to provide information for accumulation of heavy metals e.g. Pb, Cd, Zn and Cu in flesh of Oreochromis niloticus from three different Sudanese dams e.g. Jebel Aulia, Sennar and Marawi collected from upstream and downstream, respectively. A study of heavy metal concentrations in flesh of the studied fish showed that there were highly significant differences between the Pb, Cd, Zn and Cu, respectively. Heavy metal analysis from the O. niloticus muscles collected from Jebal Aulia, Sennar and Marawi dams showed that there were significant differences in Pb, Cd, Zn and Cu accumulated in O. niloticus muscles collected from the three different localities. All statistical analysis was carried out using Statistical Analysis program (SPSS,17) performed using one way analysis of variance (ANOVA) and Duncan’s multiple Range Test, to determine differences between metals means at significance rate of P
