| 摘 要： | 硝基多环芳烃类化合物是一类强致突变和致癌物.大气中的硝基多环芳烃主要由化石类燃料燃烧时直接释放,或由前体化合物多环芳烃经光化学反应生成,其浓度远低于多环芳烃.利用高效液相色谱法,分离并富集目标组分,结合气相色谱-质谱技术,建立大气气溶胶中硝基多环芳烃类化合物的检测方法,仪器检测限为1.17～2.94pg,硝基多环芳烃指...

| Abstract: | Nitro-polycyclic aromatic hydrocarbons (nitro-PAHs) are potentially mutagenic and carcinogenic.The major sources of nitro-PAHs are believed to be direct emission from fossil fuel combustion, as well as formation from photochemical reaction of precursors PAHs with atmospheric oxidants.Their atmospheric concentrations are much lower than those of PAHs.The goal of the present work was to develop an analytical method using high performance liquid chromatography (HPLC) to separate and enrich the target fraction and consequently measure it by gas chromatography/mass spectrometry (GC/MS).The instrument detection limits (IDLs) ranged between 1.17~2.94 pg.The recovery of nitro-PAH surrogate was 88.5%.The recoveries of target compounds were between 33.1%~100% and RSDs were 5.07%~15.7%.The method features good accuracy, precision and reproducibility.Nine nitro-PAHs were determined in aerosol samples collected on a roadside with heavy traffic in Shanghai.The concentrations were between 1.82~398 pg · m-3. |
