Eco-physiological Impact Of Industrial SWE Prepared From A Caustic-Chlorine Industry On A Fresh Water Fish and Its Eco-Toxicological Significance.

Abstract Industrial solid waste cause significant damage to the environment and inhabiting fauna.The solid waste was dumped near the river bank. During rainy season, the washings of the solid waste enter in to the river. The leached chemicals contaminate the surrounding areas and the lechate also enter in to water bodies. In the present study we have selected this lechate as the test material. As the chemical concentration varied in each and every collection, it was planned to prepare the lechate waste in the laboratory which we call as SWE. In the present study, the SWE exposed fish appeared lethargic after exposure to the SWE compared to control fish. The major clinical symptoms such as inappetance and ataxia appeared after 2 to 3 days exposure. At higher concentrations of the SWE, the exposed fish showed erratic movement leading to collision to inner side of the aquarium. Fish death started in exposed aquarium after 20days of exposure. The whole body oxygen uptake decreased with the increase in exposure period. When the fish was transferred to toxicant free medium, no recovery was noted. It seems 28days of exposure to the SWE was enough for the fish not to recover 100%, showing a damage of 99.9% when compared to 28d control value and finally all the 28d exposed fish died after 22d of recovery onwards indicating permanent damage to the metabolic and biochemical systems caused by mercury. The exposed fishes also showed depression in active metabolism and significant decrease in whole body respiration rate. Further cellular respiration also indicated that SWE exposed fish tissues showed significant depression in respiratory activity at all exposure period. No significant recovery was noted indicating severe damage to the metabolic system. The enzyme activity also showed similar depletion in tissue slice respiration rate. Significant depletion of total ATPase activity, affected the movements of ions across the membrane and severely affected the energy metabolism and disturbed energy budget of the fish. The SWE is toxic and can kill all the inhabiting plants and animals including fish and man in long run. Care should be taken, the effluent and solid waste of the industry should be treated before disposal into aquatic ecosystems to protect the environmental segments from mercury contained toxicants.
