“…As previous work had shown (14) that Deniges reagent can be reduced by materials other than chrysanthemic acid without the formation of a colored precipitate, it was considered that the apparently specific color reaction of Denigfes reagent with chrysanthemic acid might give values uninfluenced to a substantial degree by extraneous material. It was also hoped to avoid errors likely to occur with pyrethrins in the AOAC 1947 Method and errors in spectrophotometric analysis in the ultraviolet range (3,15) caused by the presence of biologically inactive material, such as polymerized material and unsaturated fatty acid esters (8).…”

Ix recent attempts to estimate small quantities of pyrethrins in flour which had been stored in pyrethrum-treated cotton bags ( 14), the extraction from cotton, paper, and other media was found to be difficult and there were apparent limitations in the accuracy of the analysis of pyrethroids-i.e., chrysanthemum esters of alkyl cyclopentenolones by the Association of Official Agricultural Chemists (AOAC) 1950 Method (1). Since then, these problems have been given further consideration in this

“…An infrared spectrophotometric method has been proposed for aldrin and dieldrin (68), a colorimetric procedure for piperonyl butoxide (92), an improved technique for dithiocarbamate residues permitting detection of less than 1 p.p.m. of the insecticide (114), and detection of pyrethrum in flour picked up in bags with pyrethrum-treated warp (169), and in p3rrethrum-coated paper bags (53).…”

“…Edwards and Cueto (28) developed a procedure for the colorimetric estimation of pyrethrins on coated paper bags utilized for control in manufacture and for determining the stability of pyrethrins during storage. Schreiber and McClellan (116) developed a method to reduce the interference of fatty acids for the determination of insecticide residues found in flour from pyrethrin-treated bags. 1080, ANTU, AND WARFARIN Ramsey and Clifford (103,105) presented a method for the determination of monofluoroacetic acid in foods and biological materials.…”

INTERESTin pesticides and in spray residue has continued at a high level for several years. One manifestation of this is the formation in 1949 of the Pesticide Subdivision within the Division of Agricultural and Food Chemistry of the American Chemical Society. Another evidence was the formation of the Association of Economic Poisons Control Officials during the years 1946-1947. This includes regulatory workers and experiment station men from both state and federal governments.Much emphasis has been placed on the need for safety during application of pesticides, and safety of foods which may in some cases unavoidably retain minute residues of pesticides. The use of these chemicals to control pests is generally conceded to be imperative. Some of the newer organic pesticides are highly toxic to man and animals, although they do not have a higher toxicity than some of the older pesticides such as arsenic, and particularly nicotine, which is said by Lehman (81) to be one of the most highly toxic materials known. A clear distinction should be made between hazards during use, and food hazards.
