ABSTRACT

Concentrations of trace metals like iron (Fe), nickel (Ni), zinc (Zn), copper (Cu), chromium (Cr), manganese (Mn), cadmium (Cd) and lead (Pb) were estimated in Copepods that collected during the period of February 2017 to January 2018 from the Cochin Estuary. The concentration of trace metals in Copepods showed significant spatial and seasonal variations. The average concentration of trace metals in Copepods were found to be in the decreasing order: Fe > Zn > Mn > Cu > Ni > Cr > Pb > Cd. Correlation analysis revealed a strong positive affinity between the most of metals analysed in Copepods. Keywords: Bioaccumulation, Trace metals, Copepods, Cochin backwaters
