Commercial chemicals contribute to our social welfare, yet can pose serious problems for the environment. How do we recognise these problems? How do we manage them? How do we objectively balance environmental risks with social benefits? This book describes the principles and practices of ecological risk assessment and cost-benefit analysis, asking key but challenging questions such as ?what are we trying to protect and ?how do we undertake a cost-benefit analysis . It also shows how these principles are written into legislation. The emphasis is on the EU Directives and Regulations, with a...

At the heart of environmental protection is risk assessment: the likelihood of pollution from accidents; the likelihood of problems from normal and abnormal operation of industrial processes; the likely impacts associated with new synthetic chemicals; and so on. Currently, risk assessment has been very much in the news--the risks from BSE and E. coli, and the public perception of risks from nuclear waste, etc. This new publication explains how scientific methodologies are used to assess risk from human activities and the resultant objects and wastes, on people and the environment....

As with all ecosystems, river systems involve a complex interaction of a rich diversity of micro--organisms, plants and animals with their physical and chemical environment.

Drawing on entries from The Encyclopedia of Ecology and Environmental Management, this concise reference will provide an essential quick guide for those working in the field of environmental management: consultants, planners, environmental advisors in industry, and students.

Ecosystem health offers a fresh perspective on the management of natural resources and the environment. While some of the root concepts can surely be traced back to Aldo Leopold and even earlier, it is only in the recent decade that a substantial body of work has emerged on this topic. There is no question that a novel approach which is by its nature cross disciplinary, bridging the health and biological sciences, will initially raise a number of questions particularly pertaining to the use of metaphors and the validity of the analogy. This volume however goes beyond merely the philosophical...

It is almost thirty years since Professor G. G. Winberg established the basis for experimental studies in fish energetics with the publication of his monograph, Rate of Metabolism and Food Requirements of Fishes. His ultimate aim was to develop a scientific approach to fish culture and management, and the immense volume of literature generated in the ensuing years has been mainly in response to the demand for information from a rapidly expanding, world-wide aquaculture industry and to the shortcomings of contemporary practices in fisheries management. The purpose of this book is not to review...

The last few years have seen a number of new books on evolutionary biology. However most of these are either large or specialized. This is an attempt to produce a thin, general version for undergraduate use. Thinness, of course, demands selectivity, and the aim has been to concentrate on the principles of the subject rather than on the details-principles, that is, of both theory and practice. Thinness also sometimes means that a certain level of knowledge is assumed in the readership, but I hope that this is not the case here, and my intention has certainly been to produce something that is...
