Environmental Impact of Chemicals contains a collection of views and theoretical discussions from industrialists, scientists and regulators which outline the latest legislative position and current state of the art on the rapidly changing field of environmental risk assessment. Risk assessment in safety and, to an increasing extent, chemical product registration, has been practised for many years. It is only relatively recently, however, that it has been routinely applied to chemicals released into the environment. This book describes the underlying science of such assessment, the problems associated with it and the difficulties involved in communicating the results to the general public. The book is highly practical and written from an applied perspective, with the majority of contributors being practitioners in the field. It will prove useful to researchers and professionals in industry as well as to consultancy and governmental bodies.
