Mystus bleekeri (Day,1877) and Hypselobarbus kolus (Sykes,1839) from the Northern Western Ghats of Maharashtra harbor the riverine system in Maharashtra. Nira river located in Pune district near Bhor, is one of the natural habitats of the fishes under study. Both the fishes are consumed by the local population and are one the source of protein in their dietary constitution. The research was conducted in 2019 to determine the accumulation of heavy metals in several organs, including the liver, kidney, gut, and gills. Atomic Absorption spectroscopy was used to conduct the analysis. Heavy metals such as lead, cadmium, chromium, and copper were detected in the tissues studied in this study. The overall pattern of heavy metal distribution in various tissues is as follows: Pb > Cu > Cr > Cd. The organs with the highest concentrations of heavy metals are the gill > kidney > intestine > liver > muscle. The values obtained are under permissible level advocated by WHO, but the presence of these heavy metals is an alarming situation and would lead to bio accumulation and disturb the physiological function of fishes under study as well as cause adverse effect on human being.
