Environmental regulatory agencies in states are authorized to ban the production, sale, use of certain chemicals disposal of certain wastes, or the use of certain production processes or wastes management practices. Similarly mandatory banning or reduction of toxic substances has been proposed for implementation in some states. Policymakers could also lower concentration thresholds for allowable emissions and effluents of specific pollutants. Lowering concentration thresholds might reduce the cost of pollution prevention relative to generating and treating the waste to acceptable levels. Care must be taken, however, to ensure that facilities are not diluting the waste to achieve the new threshold or shifting it to another medium. This book is a pioneering attempt in the field of Biosocial Environment. It will be highly useful to students of Environmental Sociology, Environmental engineering, Environmental Economics and also to Biological Science students, researchers and teachers.
