Interpretive Summary:

Technical Abstract: Reliable values for fundamental physical and chemical properties of pesticides are essential for prediction of biological and environmental fate and behavior of these widely used materials. Although such data are available in numerous compilations, in many cases information is provided with little or no indication of data quality and without reference to the method of determination or to the source of the data. This has led to a worldwide situation in which users of pesticide information are often unaware of discrepancies, uncertainties and errors in compiled data. IUPAC, the International Union of Pure and Applied Chemistry is engaged in a joint Project of its Divisions of Chemistry and the Environment, and Analytical Chemistry, to exhaustively compile and critically evaluate all available experimental data for a suite of physical and chemical properties and to produce a Compendium of Fundamental Physical and Chemical Properties of Selected Pesticides. We are compiling value, precision and accuracy estimates for aqueous solubility, vapor pressure, melting point, vapor pressure, Henry's law constant, n-octanol/water partition constant, acid-base constant(s), and solubility in acetone, toluene and hexane for 60 important pesticide chemicals. Forms have been developed and an internet-based system has been set up. We encourage interested scientists to contact the authors for additional information and possible collaboration in this project.
