Sherma, J. MANUAL OF ANALYTICAL QUALITY CONTROL FOR PESTICIDES AND RELATED COMPOUNDS, IN HUMAN AND ENVIRONMENTAL SAMPLES. A COMPENDIUM OF SYSTEMATIC PROCEDURES DESIGNED TO ASSIST IN THE PREVENTION AND CONTROL OF ANALYTICAL PROBLEMS. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/1-76/017 (NTIS PB261019), 1976.
Description:
This manual primarily provides the pesticide chemist with a systematic protocol for the prevention and control of analytical procedures which arise in the analysis of human or environmental media. The sections dealing with inter- and intra-laboratory quality control, the evaluation and standardization of materials used, and the operation of the gas chromatograph are intended to highlight and provide advice in dealing with many problems which constantly plague the pesticide analytical chemist. Section 7 discusses many aspects of the problem areas involved in extraction and isolation techniques for pesticides in various types of samples. Techniques for confirming the presence or absence of pesticides in sample materials are treated, at some length. This highly important area provides validation of the data obtained by the more routine analytical procedures. The gas chromatograph, being the principal instrument currently used in pesticide analysis, often requires simple servicing or troubleshooting. A section addressing some of these problems is included. Last, but by no means least in importance, is a short dissertation of the value and need for systematic training programs for pesticide chemists.
