Heavy metal Pollution in East Berbice-Corentyne Coast, Guyana - Sivakumar Rajeshkumar
The book documents the physical-chemical distribution of heavy metal in biotic and abiotic components with reference to hydrological characteristics of East Berbice-Corentyne Coast, Guyana. Besides heavy metal concentrations increased in water and sediment samples of the polluted sites. It also provide information on the bioaccumulation of heavy metals and its associated histopathological perturbations were studied in various tissues of M. cephalus collected from polluted and compared with the fish collected from less polluted of Corentyne coast. The presence of large lipid droplets in liver and increase of mucous cell in gill were some of the most noticeable alterations observed and were related to heavy metal contaminates.
