Bioaccumulation of Lead in Rohu (Labeo rohita) Fish Collected from Four Different Locations of Yamuna River in Delhi Region

Heavy metals are ubiquitous and persistent pollutants thus pose a huge risk in nature. Lead is one such heavy metals, which is known to cause many lethal/sub-lethal toxicities in aquatic animals. Lead is also known to cause phytotoxicities in aquatica and terrestrial plants. This study is an attempt to identify the bioaccumulation of lead in Labeo rohita and the location differences of the bioavailability in different tissues. High concentration and bioaccumulation were observed in specimens collected from various locations and found to be higher than the permissible limits for human consumption.
