Description

This book is specially designed for B.E./B.Tech. students of all branches of engineering and technology. The book is highly informative on different aspects of the environment. Efforts have been made to explain the fundamental concepts in a simple but comprehensive manner so that students can use this book as a reference. Topics include: Ecology, Atmosphere, Noise pollution, Ozone, Air pollution control, Metal and nuclear pollution, Sustainable development, Hardness of water, Biodiversity, Greenhouse effect, Solid waste management, Air pollution, Water pollution, Population and growth, Environmental management system. The unique strength of this book is the scientific approach. Mathematical problems and model questions, including multiple-choice questions, short-answer-type questions and long-answer-type questions are provided in Appendix II of this book as exercise for students. The book also covers details of the ISO concept of environment management system or EMS, covering environmental audit, technology diffusion, LCA model and EIA.
