  • Toxicological Impact of Benzenehexachloride on the Behaviour and Neuropathology of Heteropneustes fossilis. Organochlorine pesticides are widely used in the vast agricultural fields of Assam, India. Runoffs from treated fields contaminates nearby bodies of water with organochlorine compounds, which are neurotoxic to the ichthyofouna. The present work was designed to study the effect of bezenehexachloride on the behaviour and histopathology of Heteropneuates fossilis, as an experimental model.The experimental fish were exposed to different concentrations of the pesticide for 72 hours. After exposure, the fish exhibited various behavioural changes. Histopathological examination of brain tissue revealed cytopathic and gross histopathological alteratios, including necrosis and infractional changes. These results are consistent with the finding that organochlorides cause neurotoxic effects.

Abstract: Toxicological Impact of Benzenehexachloride on the Behaviour and Neuropathology of Heteropneustes fossilis. Organochlorine pesticides are widely used in the vast agricultural fields of Assam, India. Runoffs from treated fields contaminates nearby bodies of water with organochlorine compounds, which are neurotoxic to the ichthyofouna. The present work was designed to study the effect of bezenehexachloride on the behaviour and histopathology of Heteropneuates fossilis, as an experimental model.The experimental fish were exposed to different concentrations of the pesticide for 72 hours. After exposure, the fish exhibited various behavioural changes. Histopathological examination of brain tissue revealed cytopathic and gross histopathological alteratios, including necrosis and infractional changes. These results are consistent with the finding that organochlorides cause neurotoxic effects.
