Environmental Risk Management

The contribution to the greenhouse effect by a gas is affected by both the characteristics of the gas and its abundance. For example, on a molecule-for-molecule basis methane is about eighty time’s stronger greenhouse gas than carbon dioxide, but it is present in much smaller concentrations so that its total contri- bution is smaller. This book gives a simple and lucid exposition of the basic concepts, principles and practices of environmental risk assessment and presents the accomplish- ments of some latest thinking and research in this field of study.
