Heavy metal accumulation in freshwater ecosystem has become one of the major aquatic environmental concerns for flora and fauna due to their higher stability bioaccumulation as well bio-magnification properties. Furthermore, passing through food web, these heavy metals affect human populations ultimately. This study assessed Cirrhinus mrigala spring, autumn, winter at different locations (I, II, III) Panjnad headwork. health risk assessment consumption C. from sampling was also carried out. Fish were collected upper (I), middle (II), lower (III) stream on a monthly basis. The current evaluated Aluminum (Al), Arsenic (As), Barium (Ba), Lead (Pb) various fish organs (liver, kidney, gills, fins, skin, muscles bones) potential hazard indicators. results demonstrated significant difference (p < 0.05) organs, seasons, locations. Al, As, Ba, Pb considerably liver kidney compared other body followed trend > gills fins skin bones muscle overall mean concentrations tissues order Al As Ba Pb. concluded that caught headwork is not safe values TTHQIng (3.76), THQIng (3.27) CRIng (6.4742).
