Synopsis In order to understand man’s social relationship with his environment, it is necessary to review his more recent evolution briefly. During the past two and a half decades a wave of the environmental consciousness and concern is being discussed and developed in India and other countries. This book is an effort to keep pace with the continuing rapid developments in all areas of environmental pollutions. Specially the types of environmental pollutions such as air pollutions, water pollutions, marine pollutions etc. Each topic covered in this book is self-sufficient in itself because it not only covers the scientific discussion of each type of pollution, its adverse effects on man and on environment but also the numerous methods of its control. This book will be of immense value and beneficial to the students, academics, researchers and activists/agencies/departments concerned with environment.
