Introduction Municipal Solid Waste is a growing menace in present times. Population increase has added the problem many fold. Waste materials or the leachates so formed during the course of time may percolate to the ground water table. This may cause the pollution of ground water and ultimately affects the health of local inhabitants. Leachates are formed by slow decomposition of municipal solid waste. These leachates may run off in the nearby natural water resources such ...
Introduction The study area spreads in an area of 650 Km part of Krishna River. It is one of the densely cultivated tracts and serves as leading producer of number of crops especially sugarcane, paddy and wheat. The high stress on ground due to pumpage of large quantities of ground water for irrigation has threatened the sustainability of agricultural development. Therefore, it is necessary to adopt exploitation of ground water to its availability accordingly a refined quantitative evaluation...
Introduction Water is one of the most essential substance needed to sustain human life, animals, plants and other living beings. Without water no life is possible on earth. Now a days, water pollution is a burning issue of all over the world. The situation of water pollution in India also reaches into alarming position. All the water resources of our country such as rivers, lakes, ponds as well as ground water have become much more polluted. Adequate water resources for future ge...
Introduction Water is considered absolutely essential to sustain life. In India ground water has a major role to satisfy the needs of domestic and agriculture purposes. The ever growing demands for water resources coupled with the rate at which much of the earths fresh water being adversely affected by human activities, demonstrate a developing crisis and horrible future if environmental water resources are not appropriately managed.1 Bijapur is not an exception to this fut...
分析地下水理化参数的Bijapur(卡纳塔克)市辖区进行了季节性研究水的质量和适合家庭用途。Talabs(湖泊)、Baudy(由Adil Shahi Sultans于16世纪和17世纪建造的井)和钻孔是研究区的水资源。2010- 2011年，不同季节、不同地点、不同来源采集样品36份。参数:pH、EC、TDS、浊度、
Introduction Water is most essential for existence of life on earth and is a major component for all forms of lives, from micro-organism to man. Various physico- chemical parameters have a significant role in determining the potability of water. As per World Health Organization, safe and wholesome drinking water is a basic need for human development, health and well being, and it is an internationally accepted human right.1 Water intended for human consumption must be free from harmf...
对喀拉拉邦Eloor工业区井水理化质量的季节变化进行了研究。在2009年共采集了100个样品，各25个，分别位于夏季、季风前、季风后4个不同季节，分析了温度、pH值、总硬度、化学需氧量、硝酸盐、氟化物、铁、铅、汞、锌、镉等重金属的浓度。

Introduction Soils are basic to Civilization Supplying various economic and cultural services as well as being the subtract for plant and with water it constitute society's most important, source as a life support system. They provide food, fiber, support building and road help to convert sunlight to usable forms of energy and other resource. Soil the outermost layers of the earth is a product of geological processes and human intervention. Soils are integral and vital part o...
Introduction Land degradations have been a major environmental issue in tea estates of Sri Lanka compared to rubber and coconut plantations. Nearly about 80% of the land is old seedling tea which is often poorly managed (Krishnaraja, 1983). Large tracts of these old seedling tea plantations have been either neglected or left for fallows. It is estimated that about 30% of the entire tea land is marginal or uneconomic in mid country. Long steeps and poor management practices are responsible for...
Introduction Saltpan ecosystem is highly dynamic where the organisms are subjected to vulnerable physico chemical disturbances. Saltpans are unique enclosed ecosystem that are characteristically exposed to a wide range of environmental stress and perturbations manifest mainly through salinity changes. In the extreme astatic physico – chemical conditions of these hypersaline habitats only a few plant and animal species can live. Saltpan ecosystem offers a number of unique ecological ...

Introduction 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, dri...
Introduction Recent decades have seen record-high average global surface temperatures. Thermometer readings sufficient to provide reliable global averages are available back to 1850 (Brohan et al. 2006). In the past century, global surface temperature increased by about 1.5 °F (Figure 1). In the past quarter-century, according to satellite measurements, the lower atmosphere warmed by 0.22-0.34 °F per decade, equivalent to 2-3 °F per century. (Christy and Spen...

Introduction Due to environmental reason the use of elemental chlorine in pulp bleaching has been totally eliminated in most of the countries in the world. In the early 90's bleaching technology switched from elemental chlorine to chlorine dioxide based bleaching and reduced the formation of absorbable organic halogens (AOX) substantially; but still needs to improve. That is why researchers are looking for new bleaching technologies for further reduction of effluent load. To...
