The NIOSH analytical method S282 for determining dichlorvos (62737) in air is described. Samples are adsorbed on SAD-2, desorbed with toluene (108883), and analyzed by gas chromatography with a flame photometric detector. The working range of the method is 0.38 to 1.71 milligrams per cubic meter, the coefficient of variance is Analytical apparatus, reagents and procedures are described, and calculations are provided for determining sample concentrations. Data recovery, stability and breakthrough rates, and collection efficiency is included. The method was unsatisfactory because the accuracy could not be adequately determined.
