The environment has become exposed to a range of damaging contaminants from a wide variety of sources‎.‎ Regulation of and legislation against offending parties has frequently been hampered because of the difficulty of co‎-operation between disparate disciplines in the natural‎,‎ social and political sciences‎.‎ This volume forms the conclusion of five years‎'‎ collaboration between toxicologists‎,‎ economists and lawyers in the understanding and solution of the problem of accumulative chemicals‎.‎ As well as a case study of the accumulation of pesticides in groundwater in one particular region ‎(‎the European Union‎)‎‎,‎ the book forms a general study of the value of interdisciplinary approaches in environmental policy making‎.‎ The volume will be a valuable resource for a broad group of academics and researchers in the area of environmental science and environmental policy‎.‎ It will also form a useful supplementary reference text for courses in environmental policy‎,‎ science‎,‎ economics and toxicology‎.‎
