“…Recoveries of 3.1 to 27.2 mg. of ECB in vapor phase were 98 to 104 percent. KENNETT (1954) analyzed the same two compounds after hydrolysis with alcoholic sodium hydroxide, which converted only one mole of bromine from each mole of either fumigant. The sample was taken in a two-I.…”

“…Sinclair and Crandall (127) determined ethylene dibromide in air, and attained a high recovery with 50 to 300 mg. of ethylene dibromide. Kennett (68) determined ethylene dibromide and ethylene chlorobromide by absorption in alcohol and determina-tion of the liberated halogen by the Volhard thiocyanate method. The mean percentage recovery was 99.5 ± 1.3 to 1.6, when added in quantities from 1 to 30 7.…”

MOREpapers on analytical methods for pesticides have appeared in the last 2 years than in the preceding 3 years (121). The major part of these methods are micromethods, primarily for spray residue in fresh processed fruits and vegetables, as well as in fresh products, and for toxicity study. This indicates increased emphasis placed on safety by industry and by state and federal governments. The following review of methods perhaps shows a greater increase in emphasis on herbicides than any other type of pesticide, in accord with the interest that has been developing.Macromethods are available through the Methods Clearinghouse of the Association of American Pesticide Control Officials. A similar clearinghouse for micromethods should be established. Methods for the various pesticides are also included in "Condensed Data on Pesticides," first called "Pesticopoeia," the third edition of which will soon be published (4). Methods are presented to the Pesticide Subdivision of the American Chemical Society at each semiannual meeting. Many such methods were presented at the Milwaukee and New York meetings in 1951, and were scheduled to be published in a volume of the Advances in Chemistry Series.The tolerances published in the Federal Register for October 20, 1954, became official on December 20, 1954, unless challenged, in conformity with the requirements of the very recent law supplementing the requirement for tolerances in the 1938 law. Some chemicals will have a zero residue tolerance; others will require no tolerances; while specific tolerances are established for others.
