| Abstract: | A simple and rapid high performance liquid chromatograghy ( HPLC ) method for determing benzo ( a ) pyrene ( BaP ) in inhalable dust is described in this paper. BaP in the sample was extracted with 5ml of acetonitrile for 10 min at room temperature using the sonication method. The acetonitrile ~solution was centrifuged, then the supernatant was used for the determination of BaP by HPLC. A reverse phase column, a gradient mobile phase, acetonitrile/water and UV monitor ( 254nm ) were used.The recovery of BaP was 95%, the detection limit was 10-10g and coefficient of variation was 4.3%. |
