【摘要】 目的：分析两个五环烃大气污染水平及吸入危害。方法：用高效液相色谱仪对炼焦现场大气中Ｂ［ａ］Ｐ和ＤＢ［ａ，ｈ］Ａ的污染水平进行定量分析；对气溶胶粒度分布进行监测。结果：ＤＢ［ａ，ｈ］Ａ的污染水平与Ｂ［ａ］Ｐ同样严重。结论：小于空气动力学直径２．０μｍ的五环烃气溶胶占８０％左右，吸入危害严重。更多还原

【Abstract】 Objective:To analyze the air pollution level by both pentacyclic hydrocarbons and its inhalation risk .Methods:The HPLC was used for quantitatively analyzing the air pollution level by the B P and DB(a,h)A in coking field. The particles size distribution of aerosols was measured and monitored. Results: The pollution level by the DBA is heavy as same as BP. Conclusion: The pentacyclic hydrocarbons aerosol particles less than 2.0μm of AED is about 80%,and have serious inhalation risk.更多还原
