| 摘 要： | 目的 为了进一步了解汽油车尾气颗粒物的化学成分。方法 运用高效液相色谱法测定了尾气颗粒物有机提取物中6种多环芳烃含量，运用原子吸收分光光度法测定了尾气颗粒物无机提取物中5种重金属含量。结果 有提取物中6种多环芳烃按含量高低依次为：苯并（a)芘＞菲＞晕苯＞苯并（a)蒽＞Qu＋芘，其中苯并（a)芘含量占40％。无机提取物中5种重金属按含量高低依次为：铅＞镍＞铬＞镉＞锰，其中铅含量占37％。结论 汽油车尾气颗粒物含量较多的组分是苯并（a）芘和铅。

| Abstract: | Objective In oroler to deeply acquaint gasoline exhausted particles components.Methods The contents of six polycyclic aromatic hydrocarbons(PAHS)in organic extracts were determined by the high performace liquid chromatography and the contents of five metals in non-organic extract were determined by the atomic absorption spectrophotomotry.Results The Sequence of six PAHS was following the order from high to low: B(a)P >PHE>COR>B(a)A>CHR PYR.The percentage of B(a)P was 40 percent.The sequence of five metals was following the order from high to low:Pb>Ni>Cr>Cd>Mn.The percentage of Pb was 37 percent.Conclusion B(a)P and Pb were mainly components in gasoline exhaust particles. |
