The present article deals with the extent of water resources, sources and causes of water pollution, impact of water pollution on human health, and challenges, development and future perspectives of food safety.
The present investigation deals with the analysis of physico-chemical characteristics, concentration of heavy metals and textural analysis of sediments in Poovar estuary of Kerala during the period 2004-2005. Three sampling stations were selected and sediments were collected for the study.
Tannin degrading microbes isolated from tannery effluents were tested for their ability to degrade vegetable tannins in tannery effluents, along with other polluting parameters in the effluents like Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD) and Total Dissolved Solids (TDS).
Ground water samples from 83 villages in Honnali taluk of Davangere district were analyzed for their suitability for irrigation purpose with special reference to presence of fluoride content. Ground water in the study area was classified according to sodium adsorption ratio and electrical conductivity.
The physico-chemical characteristics of Kohargaddi dam water were studied during July 06-June 07. Seasonal variations in water quality parameters in rainy, winter and summer seasons. The result revealed that there were significant seasonal variations in some physico-chemical parameters. The result indicated poor status of water during summer, rainy and winter season.
Evaluation of different physico-chemical parameters of surface water samples, covering the entire industrial area of Hosur (Tamil Nadu), is carried out to assess the suitability of the water for irrigation purposes. Samples are collected during August 2005 to June 2006. Results of the present investigation are compared with the Wilcox standard value and Ayers and Westcott standard value.
The physico chemical analysis of the effluents of the amine manufacturing factory (Balaji Amines, Tamalwadi Dist, Osmanabad) and of groundwater form the (dug well and bore well) for pre and post monsoon seasons of 2006-2007 has been carried out.
Sasthamkotta Lake is Kerala's biggest fresh water lake. The lake is facing degradation due to anthropogenic activities such as directing human waste, soil erosion due to destruction of vegetation and dumping of waste from hotels and slaughterhouses. The water samples from different stations were analysed from a period March 2006 to August 2006 to investigate the water quality parameters.
Endosulfan, an organochlorine insecticide widely used in the paddy field, tea garden of Assam and N.E. India, creates serious threat to the environment as well as target and non-target organisms like aquatic and land dwelling animals. The present investigation was undertaken to study the effects of endosulfan on some hematological parameters of Channa punctatus.
The present study gives an idea of changes taking place in pollen characteristics of Delonix regia and Peltophorum inerme under the influence of air pollution. Pollen germination, viability, size and pollen tube length were the parameters studied. The reduction in pollen viability and pollen tube length was more significant in P. inerme than D.
