Heavy metals are non-biodegradable substances which cause carcinogenic effects in animals and humans. This study was conducted to determine the concentration of lead (Pb), chromium (Cr) and cadmium (Cd) in fish and water samples from Shitalakkhya River, during pre-monsoon and post-monsoon period. In water the concentration of Pb, Cr and Cd ranged from 0.01 to 0.3159, 0.322 to 0.407 and 0.0035 to 0.0085 ppm respectively. The concentration of Pb (0.089 ppm) and Cd(0.006 ppm) was higher than the WHO guideline value. The concentrations of heavy metals were season specific and a significant (p˂0.05) positive correlation exists among them in pre-monsoon period. Among the studied fish, Cr concentration was the highest in Colisafasciat us while Lepidocephalusguntea exhibited the highest accumulation of Pb. The order of heavy metal concentrations in the studied fish specieswere recorded as Cr˃Pb˃Cd. The analysis of fish samples revealed a significant (p˂0.05) negative linear relationship between Pb and Cr while a moderate positive relationship exists between Cd and Cr. The results of this study will help us to assess the health of the river and will serve as the baseline data for the identification of hazardous sfactors in Shitalakkhya River.
