Abstract: We analyzed concentrations of zinc, copper, lead and cadmium in ten commercially valuable finfish and shellfish species in the lower stretch of the River Ganga in April, 2016 using a Perkin-Elmer Sciex ELAN 5000 ICP mass spectrometer and expressed as mg kg-1 dry weight. In finfish species the concentrations of Zn, Cu, Pb and Cd ranged from 2.05±0.13 - 111.55±1.38, 1.26±0.11 - 53.15±0.60, BDL - 3.05±0.21 and BDL - 1.32±0.11 respectively. Concentrations in shrimp species ranged as follows: Zn: 1.19±0.06 - 141.21±1.50, Cu: 1.02±0.05 - 92.40±0.93, Pb: BDL - 2.01±0.17 and Cd: BDL in all the sampling stations.
