Bioaccumulation of some heavy metals in some organs of common carp (Cyprinus carpio) fish captured from Darbandikhan Lake Sirwan and Tanjaro river

This study was done in three stations the Darbandikhan dam with GPS Coordination of this station 35°7’16’’N (Latitude) 45°43’18’’ E (Longitude), Sirwan River located 35°7’17’’N; 45°50’54’’ and Tanjaro Side Site sample location details 35°14’22’’N; 45°51’58’’ to heavy metals contamination water selected organs carp lived these locations for six months. The studied include Hg, Cd, Pb, Cu, Co Cr analyzed by ICP-OES (Spectro acros). bioaccumulation levels passing time liver fishes is significant P≤0.05 all metals. Hg higher significantly November 2021 January 2022. Cd October 2021. Pb Cu September concentrations common were station, fish, fish liver. In most months gills below detectable level except which 2022 lower significantly. August 2021, each Tanjaro. increased dams. Due annual mortality Darbandikhan, river present research order detect main reasons pollution some its relation organs.
