Limnological Survey

ABSTRACT. Limnological Survey of three Tropical Water Reservoirs in Eastern India. Plankton communities of three water reservoirs of India reflect direct relationship with organic pollution. The assessment of water quality as high or low organically polluted for three water bodies have been achieved with help of algal community, which can be used as indicator of organic pollution. Algal pollution indices according to Palmer (1969) and Watanabe’s (1962) based on genus and species were used in rating water samples for high or low organic pollution. Among 26 genera found in India 20 most frequent and common genera of algae were taken into account for indexing pollution status. Water Quality Index (WQI) on the basis of weighting and rating of the chemical parameter was also used to correlate the Palmer index with Physical-chemical parameters of water reservoirs.Key Words. Palmer Index, organic pollution, water reservoir, algae, plankton, water quality index.RESUMEN. Estudio limnológico de tres embalses de la India Oriental. Las comunidades planctónicas de tres embalses de la India reflejan relaciones directas con la polución orgánica. Se ha evaluado la calidad del agua de estos embalses atendiendo a la comunidad algal que alojan, lo que puede usarse como indicador de polución orgánica. Se ordenaron las muestras de agua, desde alta hasta baja polución orgánica, de acuerdo con los índices de Palmer (1969) y Watanabe (1962) basados en géneros y especies. Entre los 26 géneros encontrados en la India, se seleccionaron los 20 más comunes y frecuentes para los cálculos de los índices citados. También se calculó el índice de la calidad del agua (Water Quality Index, WQI), y se correlacionó con el índice algal de Palmer así como con los parámetros físico-químicos del agua de los embalses.Palabras clave. Índice de Palmer, polución orgánica, embalses, algas, plancton, índice de calidad del agua.

The limited fossil reserves, spiraling price and environmental impact due to usage of fossil fuels leads the world wide researchers’ interest in using alternative renewable and environment safe fuels that can meet the energy demand. Biodiesel is an emerging renewable alternative fuel to conventional diesel which can be produced from both edible and non-edible oils, animal fats, algae etc. The society is in dire need of using renewable fuels as an immediate control measure to mitigate the pollution level. In this work an attempt is made to review the requisite and access the capability of the biodiesel in improving the environmental degradation.
