The Editors of this volume note that this marks the fXteenth anniversary sine: the publication of Volume I of this series in 1963. For those actively engaged in pesticide analyses, the initiation of this series was a welcome addition in an ma which, until that time, had little available methodology for guidance_ The entire series has been quite useful as a reference tool for those involved in pesticide analyses, especially with the numerous new classes of pesticides that have appeared on the market. The present volume discusses the chemical and biological properties of and presents the recommerzded analytical procedures for commercial formulations aad their residues present in biological materials of 15 insecticides, 8 fungicides, 21 types of herbicides, 4 plant growth regulators, and one fumigant. Many of the analytical methods are on new pesticide chemicals; several of the methods “update” the procedures for some of the old, well-known, pesticides.
The recommended technique for formulations and residues is predominantly gas chromatography; the newer technique of high-performance liquid chromatography (HPLC) is also noted in some of the procedures. Recommendations for formulation analysis show the following trend: About 43% of the methods use gas chromatography, 14:/, use HPLC, 4% thin-layer chromatography, 4 o/ocalorimetric analysis, 10% the classical titration procedures, and 14% spectrophotometry. In residue analysis, some form of gas chromatography accounts for 78% of the recoinmended analytical procedures, 10 % HPLC, and 8 76 calorimetric. Some overlapping occurs, because a choice is sometimes oEered. The chapter on the herbicides Diquat and Paraquat reviews newer techniqna on gas chromatography, but the tedious 13-year old digestion and cleanup procedure, fol!owed by calorimetry, is still recommended. Similarly, the volume contains an excellent review chapter on the organoarsenical herbicides, but the analytical meshod of choice for formulations is still based on the W-year old acid-base titration pr@ cedure. Similarly, there are still problems in this area for residue analysis, and the method of choice is usually the wet-ashing procedure, absorbing the reduced & generating amine, reacting with si!ver diethyldithiocarbamate, and measuring the end . product by means of a spectrophotometer. The chapters on chlordane (3 pp.) and heptachlor (2 pp.) are i total disappointment. These are, of course, two old pesticides, and analytical methodology is Well known for formulation analyses. However, some refinements and new reeom=eadations for residue analyses of these chemicals have appeared more recently. ‘% authors of these articles (the same authors for both chemicals) should have take; the time to point out the details of some of these newer innovations instead of r&e: m&
the reader to a large nuder of other publications, some of which-n&y not bk readily availableto the reader. These twq. chapters belie the title of this volume: A czse. in pointis the excellent chapter on ‘the s-triazines; these chemicals, aIso, are oQ wellknown,herbicides. Nevertheless, the authors produced a chapter M&b stakis .alon& withno need for numerous referencesto related pubiications. A timely and exceltsnt chapter is included QQ hexacbloropheneifor years consideredto be primarily a bactetiostat and only recentlyrecogked as a chemicaf to control seedling disease, rot, &.td as a fungicidalagent on some agric~&~~%~ products. The Editors are to be commended for their continued efforts to &e&pthe pesticide analyst updated on proceduresfor the newer pesticidesand for the pub&ztionof revised methods on t&e older ~hernicak.This volume should be added $0 the libraryof every pesticidechemist.
