520			_aIt is a well-known fact that the environment is continuously and consistently polluted by each passing day both by natural process and man-made sources. The natural processes include forest fires, natural organic or inorganic decays, volcanic eruptions, earthquakes etc. The man-made sources include rapid population explosion, deforestation and modern technology. In fact, rapid industrial and technological developments all over the world have resulted in release of poisonous matter (gases and other byproducts) into air, water and land. The manufacturing units engaged in the production of drugs, antibiotics, dyes and agrochemicals have added to the environmental pollution. Excessive use of agrochemicals has added to the problem of soil pollution. All these pollutants have hazardous effect on human health. Besides, some of the pollutants are also responsible for Global warming, Ozone layer depletion and Acid rain. In view of the hazardous effects of various pollutants, as a first step it is important to test the presence or absence of these pollutants and subsequently their estimation. This requires the use of highly sensitive and accurate but complex instruments. The present book deals with analysis of such pollutants in air, water and land. Air pollutants include the gaseous pollutants like carbon monoxide, carbon dioxide, sulphur dioxide, nitrogen dioxide, hydrogen sulphide and solid pollutants like particulate matter, metallic pollutants etc. Besides, noise and radioactivity are other pollutants in the air. The water analysis include determination of water quality parameters, including total dissolved solids in water, determination of alkalinity and concentration of ammonia, nitrogen, soluble chloride, soluble sulphates and nitrates. The pH of water, its conductance, hardness, Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD) are other parameters which must be determined. Metallic pollutants in water include- trace elements, mercury, cadmium, arsenic, lead, selenium, beryllium, chromium, copper, iron. Other pollutants include fluoride, pesticides and radioactivity. Methods of estimation of all the water pollutants have been described. Soil analysis includes determination of its pH, conductance, amount of organic matter, available nitrogen, sulphur, phosphorus, manganese, calcium, magnesium, iron, sodium, potassium, pesticides and water soluble cations and anions. Methods for the detection and estimation of all the pollutants in soil have been described. It is hoped that this book will be extremely helpful for all studying Environment.
