Pesticide Residues: A Contribution to their Interpretation, Relevance and Legislation contains the papers presented at two special Symposia held in the Pesticide Residues Section at the Fourth International Congress of Pesticide Chemistry (lUPAC). This book is organized into two parts encompassing 17 chapters. Part I focuses on the accuracy of any statement on the amount of residue a sample contains, which is influenced by the interaction of multiple factors. This part specifically discusses some of these factors and their bearing on the analytical result of pesticide residue analysis. Part II deals with the complex problem of whether and how the unavoidable uncertainties in analytical findings can be matched to a legislative machinery accustomed to operating with rigid data. This part also covers the principles for the permission of pesticides from the food-hygienic point of view, with emphasis on regulatory toxicology and tolerances of pesticide residues. This book will be of value to toxicologists, agriculturists, public health workers, and legislators.
