Abstract: Water is the main source for the development for all human beings, cattles and industries. From the history of the global system, we learn that in ancient days, perennial rivers become the major source of water and the people, who were far away from the river sources, practiced the utilization of ground water and stored rain water for their future purpose. In India ground water utilization has been practiced since many centuries. But at present, because of excess population and industrial developments the ground water is exploited to a great extent. Rain water harvesting is the technique of collection and storage of rain water in surface or in under-ground aquifers before it is lost as surface run-off.

Abstract:The effects of heavy metals on the histopathology gills of the fresh water bivalve L.marginalis was investigated. Samples were collected from the Godavari river at paithan. The bivalves were exposed to 1.6 ppm CuSO4, 0.6 Hgcl2 and 3.9 ppm Cdcl2 for 72 hours acute treatment. For chronic exposure were exposed to 0.82 ppm CuSO4, 0.32 ppm Hgcl2 and 1.95 ppm Cdcl2. Histopathological changes observed in the gills were edema and lifting of lamellar epithelia ,lamellar degeneration, necrotic changes in intercellular epithelial cells. This research simulate a reliable indicator of the aquatic ecosystem contamination and the possible negative impact of the surrounding environment

Keywords: Lamellidens marginalis, gills, histopathology heavy metals

Abstract: Coal fly ash is an industrial waste from PLTU industrial activity, such as PLTU Asam-Asam lies in Kab. Tala from South Kalimantan Province which use coal as its fuel. Generally, fly ash would be thrown over landfill or being piled up within industrial area. Piling up of this coal fly ash in certain period would be highly accumulated in certain location and causing problem for environment due to its ash waste which is included in dangerous and toxic waste material (B3) thus creating problem for industry itself. Therefore, utilization effort for this fly ash is highly needed to improve its economy value and to reduce its negative effect toward environment.

Abstract: An extract of Datura stramonium was screened for phytochemical analysis and antimicrobial assay against different bacterial species. The solvent used for extract preparation was methanol. Phytochemical analysis of leaf extract shows presence of Alkaloids, phenols, carbohydrates, glycosides, Terpenoids, steroids and proteins. Agar well diffusion method was used for study of antimicrobial activity of leaf extract. Standard antibiotic (Azithromycin) and methanol were used as a positive and negative respectively. Leaf extract of Datura stramonium shows strong antimicrobial activity against bacterial species like Bacillus thuringiensis, Pseudomonas aeruginosa, Agrobacterium tumefaciens and Klebsiella pneumoniae.
