    Abstract:
    OBJECTIVE: To establish a method for determination 1-bromopropane (1-BP) in workplace air by gas chromatography-flame ionization detector (GC-FID). METHOD: 1-bromopropane in workplace air was collected with activated charcoal tube, then desorbed by carbon disulfide and determined by GC-FID. 1-bromopropane was quantitatively measured using retention time and peak area. RESULTS: Linear regression formula was Y = 3353.4x-10064 in a range of 2.50 ∼ 500.00 µg/ml with regression coefficient R = 0.9998. Detection limit was 0.25 µg/ml and the lowest detection concentration of 1-brmopropane in air was 0.14 mg/m(3) (at air volume 1.8L). The mean recoveries of 1-BP were between 96.8% and 102.6%, and relative standard deviation of inter and intra-assay was less than 10%. The average desorption efficiencies were between 93.2% and 104.4%. The samples in activated charcoal tube could be stably stored for 5 days at room temperature. CONCLUSION: The method could be feasible to determine 1-bromopropane in workplace air.
