A study was carried out on toxic effects of cadmium nitrate on chlorophyll content of soybean and pigeon pea for two crop seasons. The concentration studied were 0.01M, 0.001M and 0.0001M. Chlorophyll content markedly decreased in all the treated plants and the decline was directly related to the concentration.

In the present work, both commercial and R&D stage biotechnological applications relevant for the pulp and paper industry are reviewed. In general, the application in this module involve the use of enzymes or micro-organisms to improve the process efficiency, product properties or quality or to decrease process energy or chemical consumption.

The Asia-Pacific marine resources are economically important to most countries. It is the centre for global mariculture. But, now, it has become a major cause of concern as this area is continuously being exposed to heavy pollution and increase in fish catch using destructive fishing techniques. The impact of aquatic pollution on lakes and marine environment is discussed in present paper.

The acute toxicity of phosphate fertilizer on the survival level of Tilapia Zillii fingerlings was determined in 96hr static bioassay. The fish were exposed to different phosphate fertilizer concentrations. During the exposure period, there were frequent attempts at jumping out of the tank, loss of equilibrium, agitated swimming, air gulping and finally death.

The effects of an insecticide monocrotophos on some biochemical parameters of the fish, Tilapia mossambica at 24, 48, 72 and 96 hrs of exposures were studied. Median lethal concentration of monocrotophos to the fish for 24 hour exposure was determined during bioassay study. The protein contents were found to be declined in all the samples analyzed during all the exposure periods.

Water quality of lake normall get contaminated every where by accumulaton of sediments, human waste, silt, organic matter, industrial waste but in India different type of religious activities (idol immersion) are taking place every year, to which other countries are not concerned. The water bodies selected for the study are Upper and Lower Lakes of Bhopal, Madhya Pradesh.

In Shiraz plain, there are 1070 ha of agriculture, 540 hectares of that is used for, vegetable cultivation. Two rivers are crossing Shiraz plain west to east. They are called Khoshk river and Soltanabad river. East and south of the city of Shiraz in two seprate countryside, people use polluted river waters for vegetable cultivation by pumping.

Determination of source of fecal pollution in rural water by the use of antibiotic resistance profiling is promising and the patterns of MAR in different animal populations vary according to the types and quantities of agent used.

To meet the growing population demands rainwater harvesting is the need of the hour. The study area was a site in Kathacheruvu Village, Anantapur District. Past rainfall records were collected and annual rainfall was computed. Water levels in the open wells and bore wells near the site were measured at suitable intervals during pre and post monsoon season. A rain water harvesting structure i.e.

Experiments were carried out in laboratory using small reed bed to treat municipal sewage.
