ABSTRACT
<p><b>OBJECTIVE</b>To establish the method of detecting the concentrations of bisphenol A (BPA)in air of workplaces with high performance liquid chromatographic (HPLC).</p><p><b>METHODS</b>According to standards of methods for determining the chemical substances in workplace air, BPA in the air was collected by glass fiber filter, then dissolved by acetonitrile and determined by high performance liquid chromatography with FLD.</p><p><b>RESULTS</b>There was a linear relationship within the range of 0.01-10.0 pg /ml, and the detection limit was 0.005 pg/ml. The lowest detected concentration was 3.3x10-5 mg/m3. The relative standard deviation was 2.5-5.5%. The dissolution efficiencies were 95.0%-101.9% and the sampling efficiencies were 99.6%. The samples in glass fiber filter membrane could be stored for 7 days at room temperature.</p><p><b>CONCLUSION</b>The present method could meet with the requirements of Guide for establishing occupational health standards-Part 4 Determination methods of air chemicals in workplace and be feasible for determination of BPA in workplace air.</p>
