Regulating Chemical Accumulation in the Environment : The Integration of Toxicology and Economics in Environmental Policy making 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 Preface: the regulation of pesticides in Europe past present and future Marco Vighi Carolina Sbriscia Fioretti and Timothy Swanson Regulating chemical accumulation: an integrated approach Timothy Swanson Chemical characteristics: the case of herbicides in Italy Carolina Sbriscia Fioretti Giuseppe Zanin Paolo Ferrario and Marco Vighi Valuing chemical characteristics: a hedonic approach Tore Söderqvist Environmental toxicology: the background for risk assessment Marco Vighi Richard Lloyd and Carolina Sbriscia Fioretti The value of changes in health risks: a review Magnus Johannesson and Per Olav Johansson On estimating the benefits of groundwater protection: a contingent valuation study in Milan Jane Press and Tore Söderqvist Market failure Robin Mason Regulatory failure Robin Mason Optimal policies for regulating persistent chemicals Timothy Swanson An analysis of alternative legal instruments for the regulation of pesticides Michael G.
