The Assesment of Heavy Metal Toxicity in Tungabhadra River Fishes Labeo Rohita and Catla Catla.

Abstract

Pollution effecting the natural  aquatic environment due to  heavy population, and increase  industrialization in Kurnool . Humans take fish meal as a nutritional dietary uptake without the awareness of heavy metal from the polluted water bodies . The present research   focused to quantify the  heavy metals concentration in  river water and a common  edible  fishes of Tungabhadra river  areas in Kurnool. The manuscript examined the Heavy metals, which include  Arsenic (As), Cadmium (Cd), Copper (Cu), Lead (Pb), Iron (Fe), Manganese (Mn), Mercury (Hg), Zinc (Zn)  as persistent river water  pollutants can pose significant Health risks to human and Kurnool aquatic ecosystems. For this study we have chosen the fish species are Indian carps Labeo rohita and  Catla catla  as bioindicators for the heavy metal contamination in the river water. The study observed the  levels of  metals varied among the gills and liver tissue of the fish samples. The metal concentrations found in fish gill and liver tissues were comparatively  higher than the World Health Organisation regulations.
