Abstract
A procedure for determining 2,3-dibromopropanol (96139) (DBP) in air was described. Samples were collected by a simple U-tube apparatus connected to a personal sampling pump. The sampling tube contained a 20/40 mesh graphitized carbon adsorbent, 100 milligrams (mg) in the front section and 50mg in the backup section. The pump was operated at a flow rate of 0.2 liters per minute for 2 or 4 hours. The adsorbed samples were desorbed with carbon-disulfide. After standing for 20 to 3O minutes, aliquots were taken and injected into a gas chromatograph fitted with a flame ionization detector. The detection limit was 5 nanograms for a 1 microliter aliquot. When samples were spiked with liquid or vapor containing 10 to 150 micrograms (microg) DBP, recoveries of 84 to 114 percent were achieved. The mean recovery for both types of spike was 96.1 percent. The recovery of 10 blind quality control samples containing 30 to 150microg DBP prepared by NIOSH averaged 95 percent with a standard deviation of 9.5 percent after being stored 7 days at room temperature. The author concludes that the method is suitable for monitoring personal exposures to DBP.
