"Good quality water is becoming more and more scarce on global basis due to expanding urbanization and industrialization and attempts have been made to use and reuse the huge quantities of waste water generated daily by human and industrial activities without causing any adverse effect on the environment. However, disposal of pollutant contaminated waste waters on land causes soil pollution and deterioration in the quality of crop produce, edible portions of vegetables, fruits and fodders grown on such pollutant contaminated soils besides irrigation with pollutant contaminated waste water. This polluted water - soil - plant - food chain system results in enhanced risks for consumer's (animal and human) health.
This book on crop production with waste water provides a systematic information on the origin of air, water and soil pollutants, and their effect on environment, pollution through fertilizer and pesticides used in agriculture, characteristics and quality requirement of waste water reuse, effects of waste water use on soils and crops and their use in forestry are emphasized. Due importance has been given to land and crop management for waste water irrigation describing crop management, irrigation, chemical and physical management.
This book also contain waste water treatment including chemical processes and engineering aspects. However as the biological method of waste water treatment is the most effective and economical method of treatment of organic and certain inorganic pollutants due emphasis has been given to this area.
Data pertaining to Indian conditions has been given to help the reader gain an insight into India's own pollution problem. In short, this book will be of immense value to students of environmental sciences, researchers and decision makers associated with waste water management, soil and water pollution, sewage water irrigation, forestry and environment management."
