If the environment is deteriorated and degraded, polluted and defiled, filthy and disgraceful, concomitantly the speechless plants and animals, the motherly soil and the crazy human being besides the buildings and monuments suffer. While a few problems are occupational, water pollution is regional, and air pollution is global in its impact. The effluent rich water could be treated before disposal. However, pollutants once released in air can not be controlled. The main aim of writing this book is to provide the students of environmental science, a simple exposition of the subject. The book has been compiled from the point of view of the students to give them a thorough training in the principles and methods of environmental analysis. Recognising the need for standard methods in examination and analysis of environmental parameters has been long felt. The book starts with a chapter on environmental monitoring, followed by Physico-chemical monitoring to evaluate concentration of pollutants, Biomonitoring to evaluate pollutant effects, remote sensing and environmental stress. Environmental procedures for the common parameters have been discussed. There are many more parameters which should be monitored if the situation demands, but it becomes difficult when efforts are made at the level of an individual. The last chapter is detection of pollution by citizens to involve peoples participation in environmental monitoring.
