The use of fertilizers, pesticides and manure are main source of water pollution in this area. Water is one of the most important factor for every living organism on this planet. Water is generally used for drinking, fisheries and other domestic purposes in this area. The available fresh water to man is hardly 0.3 to 0.5% of the total water available on the earth and therefore its judicious use in imperative. Lakes are one of the important water resources used for irrigation, drinking, fisheries and flood control purposes. (Adarsh kumar et al. 2006). On the other hand, lakes also provide a habitat for invertebrates, fishes and aquatic birds. Therefore scientific study needs to review strategies for conservation and better utilization of lakes. It is with this background, the present work was undertaken between Dec. 20009 to Jan. 2010. Water quality index (W.Q.I.) provides a single number that expresses overall water quality at a

Objectives: To explore the use of natural composites as environmentallyfriendly alternatives to plastic. To investigate the effects of varying ratios of peanut shells and Styrene Diluted Unsaturated Polyester resin (SDUPR) on the mechanical properties of the composites and to assess the biodegradability of the composites. Method: Composites were prepared using the manual layup method. Utilized varying ratios of peanut shells and SDUPR as: 50:50, 55:45, 60:40, 65:35 and cured the composites with a curing agent. Performed mechanical tests including Izod Impact test, Flexural test, Rockwell Hardness test using standard test ASTM D256, Flexure strength testing and HR-210MR respectively. Evaluated the biodegradability of the composites. Findings:The ratio of peanut shells to SDUPR significantly affects the hardness and biodegradability of the composites. Comparisons of the four sheets provide insights into the mechanical properties of each composite and the impact of the ratio of peanut shells and SDUPR. The observed values of Izod impact test are 1.95 J/cm 2 , 1.86 J/cm 2 , 1.75 J/cm 2 , 1.69 J/cm 2 and Rockwell hardness test are 29 kg.mm, 23 kg.mm, 17 kg.mm, 9 kg.mm. Novelty: This study explores the use of natural composites made of SDUPR and peanut shells, contributing to the search for environmentally-friendly materials. It provides valuable insights into the potential of natural composites as a sustainable alternative to conventional materials.

4-Carboxaldehyde-1-phenyl-3-methyl-2-pyrazolin-5-one condensed with phenylhydrazine to form ligand (HL). These metal complexes are of type [ML2(H2O)2] (M = Mn, Co, Ni and Cu). Elemental analysis, magnetic susceptibility, electrical conductance, electronic and infrared data suggest octahedral structure for the metal complexes. All the compounds were tested for their antibacterial activity. The result indicates that the growth of the tested organisms was inhibited by most of the compounds.
