The major objective of this title is to expose the young students to the vital principles underlying impact assessment of environmental problems.
The editing to this book is based on the research and teaching experience of editors who have been actively engaged in the different aspect of environmental science. Their valuable experience has been carefully condensed in compiling this book.

This book will prove to be an invaluable reference book for all environmentalists including environmental students, biological students, engineers, doctors, city planners, health technicians and agriculture scientists who are engaged actively in the field of environmental analytical investigations including those which are mainly concerned with pollution, fishery, ecology, agriculture sanitation and health & hygiene

In many universities environmental biology has been introduced as a paper at the undergraduate as well as the post graduate level. But there are very few books on this subject. Therefore, an attempt has been made to write the book on the said subject. The order of the topics covered in this book may not be able to satisfy every one.
