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/m3(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.
