[Determination of 16 PAHs from atmospheric particulate matter PM2.5 in certain ironworks district by HPLC].
The paper describes the determination of the 16 polycyclic aromatic hydrocarbons (PAHs) prescribed by Environmental Protection Agency in PM2.5 in certain ironworks district of Beijing by HPLC. A HPLC method of VWD-FLD connected in series was founded. The 16 PAHs were completely separated by the method. The earlier eluted ten PAHs were detected by VWD and the rest were detected by FLD. The minimum detection limits of the 16 PAHs vary from 0.29 microg x L(-1) (for Bkf) to 50.6microg x L(-1) (for Nap), the average recoveries range between 85.1% (for Nap) and 103.2% (for Fla) and the relative standard deviations are between 4.31% (for Flu) and 9.93% (for Ind). The detection results indicate that the pollution situation is still very serious in this district.
