Description:

This new edition provides a good exposure to the multidisciplinary nature of the subject and deals with various life supporting systems, their ecological aspects and effects on the sustenance of life, covering the bio-geochemical cycles in sufficient detail.Useful for courses taught in departments of science and environment, biotechnology and chemical engineering, the text presents an overview of important aspects of air and water pollution, especially the effects of industrial activities on pollution.Chapters seven and eight, which are new to this edition, discuss chemical toxicology, and waste management _ an area of great importance today.

Key Features:

· Discusses catastrophic depletion of oxygen and molecular mechanisms on mutagenesis, and their overall impact on the environment.· Analyzes the quantification of pollutants through microbiological and biochemical techniques; eutro-phication level and its impact on Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD).· Explains the role and implication of some less common pollutants such as metals, mines, and polymers.
