    Comparative Account of Untreated and Treated Sago Effluent Analysis by Investigating Different Physical and Chemical Parameters
    (International Journal of Pure and Applied Sciences and Technology, 2013) F. Ramesh; K. Nagarajan; A. Gracelyn Portia
    With the rapid growth of industries, pollution in natural waters by industrial wastes has increased tremendously. Due to lack of treatment and improper modes of disposal of wastes, the water bodies are polluted and they carry deadly substances. The present work aims at studying the nature of untreated and treated sago effluent to make a comparison of the quality of effluent water that are discharged into the water system. The untreated and treated sago effluent samples were collected from the factory and the physico chemical parameters were analyzed. The results were compared with ISI standard. The results are tabulated and conclusions are drawn.

    Histopathological Changes in the Gill Tissue of the Fish Catla catla Exposed to Untreated and Treated Sago Effluent
    (International Journal of Environmental Sciences, 2014) Ramesh. F; K. Nagarajan
    Pollution of the aquatic environment is a serious and growing problem. Increasing number and amount of industrial, agricultural and commercial chemicals discharged in to the aquatic environment having led to various deleterious effects on the aquatic organisms. Aquatic organisms, including fish, accumulate pollutants directly from contaminate water and indirectly via the food chain. The study of histopathological effects of pollutants on the different organs of the fishes is an important basic effort leading to our understanding of true impact of pollutants on that ecosystem because the fresh water fish show dissimilar pattern of response when exposed to toxicants. In the present study the histopathological changes are observed in the gill tissue of the fresh water fish Catla catla exposed to 50% and 100% concentrations of untreated and 100% treated sago effluent. The histology of gill tissue showed various degrees of deterioration when compared to control. The deterioration was very much reduced in the treated sago effluent when compared to the untreated sago effluent.

    Histopathological Changes in the Muscle Tissue of the Fish Clarias batrachus Exposed to Untreated and Treated Sago Effluent
    (Advances in Bioscience and Bioengineering, 2013) Ramesh. F; K. Nagarajan
    The histopathological changes are observed in the muscle tissue of the fresh water fish Clarias batrachus exposed to different concentrations of untreated and treated sago effluent. The concentration chosen for untreated effluent and treated effluent were 50% and 100%. The histology of muscle tissue showed various degrees of deterioration when compared to control. The deterioration was very much reduced in the treated sago effluent when compared to the untreated sago effluent.

    Histopathological changes in the retina of the fish Clarias batrachus exposed to untreated and treated sago effluent
    (International Journal of Development and Sustainability, 2013) F. Ramesh; K. Nagarajan
    The histopathological changes are observed in the retina of the fresh water fish Clarias batrachus exposed to different concentrations of untreated and treated sago effluent. The concentration chosen for untreated effluent and treated effluent were 50% and 100%. The histology of retina showed various degrees of deterioration when compared to control. The deterioration was very much reduced in the treated sago effluent when compared to the untreated sago effluent.
