The concentrations of polychlorinated biphenyls (PCBs) and residues of organochlorine pesticides (HEOD and DDE) were measured in livers of otters (Lutra lutra) from different areas in Scotland. Whilst HEOD and DDE occurred at very low concentrations only, PCBs were present in high levels in some areas, the highest in Shetland (geom mean 2.05 ppm wet wt), related probably to high levels in sediments in the north-east Atlantic. PCBs were a mixture of congeners in which higher-chlorinated ones predominated, especially 138, 153, 170 and 180, a pattern comparable to that observed in otters from continental Europe. Individual values of total PCB reached levels of over 14 ppm wet weight, even in otters in good condition in thriving populations. Otter population densities were known in some of the study areas; in Shetland numbers increased over the study period, and the density was relatively high also elsewhere in Scotland. There was a strong negative correlation between PCB and body condition, but no correlation between PCB concentration and age of otters (mean age=4.1 years), which suggests that PCBs do not accumulate substantially in otters in the long term. The observations cast doubt on the significance of published 'critical levels' of PCBs to otter populations, based on data obtained from captive mink.

This landmark book, which contains contributions from the world's foremost mammalian ecotoxicologists, is a truly impressive summary of research undertaken in this field in recent years. It is also the first book to draw such information together in a seamless and unified approach. In examining the exposure and effects of environmental contaminants in wild mammal populations, this book addresses four core questions: * What exactly do we know about environmental contaminants in wild mammals? * What are the commonalities and differences between mammal orders/species in the effects that contaminants have? * How and to what degree of accuracy can we predict the adverse effects of environmental contaminants on mammalian wildlife? * How significant are contaminant insults compared with other density-independent and -dependent factors such as habitat loss, climatic factors and disease? The key underlying scientific principles and issues raised by the team of international authors will have significance throughout the world, making this an invaluable book not only for all those studying the effects of environmental pollutants on mammals, but also on regulatory agencies, and those carrying out environmental impact assessment.

The edited book Pesticides - Toxic Aspects contains an overview of attractive researchers of pesticide toxicology that covers the hazardous effects of common chemical pesticide agents employed every day in our agricultural practices. The combination of experimental and theoretical pesticide investigations of current interest will make this book of significance to researchers, scientists, engineers, and graduate students who make use of those different investigations to understand the toxic aspects of pesticides. We hope that this book will continue to meet the expectations and needs of all interested in different aspects of pesticide toxicity.

This book is about the varied range of emerging applications using specially trained detection dogs to monitor and protect aquatic ecosystems, animals, plants and related resources. Featuring contributions from those at the forefront of converging disciplines ranging from canine training, ecological and biological monitoring, water resource management, law enforcement, and eco-toxicology, it addresses everyone already immersed in these or related fields, and anyone seeking to gain a broader understanding of them. Chapters cover several common themes including monitoring presence/absence through biological and ecological surveys; maintaining and evaluating water quality; law enforcement and anti-poaching initiatives; public education, awareness and compliance; standards and best practices; optimal uses of dogs in relation to and in conjunction with other available tools and pragmatic considerations for selecting and working with dogs and handlers. The aim of the book is to stimulate new ideas, promote the sharing and dissemination of information and findings - and, ideally, to catalyze new and innovative partnerships, to strengthen the preservation and conservation of our aquatic heritage.
