About the Book
Rapid strides have been made in the field of industry in India. The net contribution from industry has been increasing over time vis a vis agriculture. With the improvement brought about in the standard of living and life styles of the country's population, concerns have been expressed about the mounting pollution and the consequent environmental degradation. Hence, a close monitoring is required on the imminent threats posed to the environment. In this direction the present practical manual is oriented for Undergraduate students, towards learning by doing concept in the areas of soil, water, air, noise pollution and in developing indices on plant under stressed conditions. We hope that the practical manual being the first of its kind would be a forerunner to take up similar activity for students and bring about awareness among the citizens in the forthcoming years by the University Grants Commission which had already prescribed a common syllabus for all the degree programmes of the country.
