Assessment Of Heavy Metal Bioaccumulation In Tilapia And Labeo rohita From Kachapur Lake, Kamareddy, Telangana, India

Abstract

The present investigation revolves around heavy metal accretion into Kachapur Lake, located in Kamareddy district and its subsequent adverse effects on the fish resident populations. The overall aim of this research is to determine heavy metals concentrations in lake waters, sediments and fish tissues with a view to assessing their relationship with regard to fishes’ mortality. This entails collecting samples of water from different parts of the lake, as well as sediment samples and even fish specimens for further analysis. Available key heavy metals include lead (Pb), mercury (Hg), cadmium (Cd), chromium (Cr) etc which are assessed through state-of-the-art analytical techniques. At the same time instances of fish deaths are recorded so that possible links with accumulation of heavy metals can be investigated. An understanding of heavy metal contamination in aquatic environments is vital if corrective measures towards this global problem are to be put in place.
