Urinary 1-hydroxypyrene of residents of Beijing, Shenyang and Taiyuan, and workers at two coke plants, a steel plant and control groups was determined using high pressure liquid chromatography. Polycyclic aromatic hydrocarbons (PAHs) of airborne particulates from these cities and coke plants were analyzed using GC-MS; chromatogram profiles, from which 15 chemical compounds were quantified, were similar. The percentage of pyrene and benzo[a]pyrene in PAHs was fairly constant. Statistical… CONTINUE READING
