Traditionally the province of chemists, the problem of environmental pollution is increasingly being tackled using methodologies which have a biological basis. This volume provides a range of examples of how biotechnology can offer sensitive and ecologically-relevant new ways of monitoring the presence of biohazards in our environment and, once detected, how these biohazards can be removed in an ecologically safe way through bioremediation. Additional chapters on economic, legislative and policy aspects set the topic in its social context, resulting in a broad-ranging volume of value to all those concerned with the science of ecologically effective environmental protection and management.
