摘要
对广佛公路两侧气溶胶中有机污染物进行监测调查,发现气溶胶中具有较高含量的芴、菲、蒽、荧蒽、芘、苯并[a]蒽、、苯并[b]荧蒽、苯并[k]荧蒽、苯并[a]芘、茚并[1、2、3-cd]芘、二苯并[a、h]蒽、苯并[g、h、i]苝等。通过TSP研究认为,主干道的机动车排放和扬尘是气溶胶的主要来源,多环芳烃从机动车排放出后在迁移扩散过程中有因质量数差异而发生分离效应。通过对比可知,该区域测点多环芳烃有机污染物极大程度地高出环境背景区。
There are high contents of fluorene, phenanthrene, anthracene, fluoranthene, pyrene, benzo [a] anthrancene, chrysene, benso [b] fluoranthene, benso [k] fluoranthene, benso [a] pyrene, indeno [1, 2, 3-cd] pyrene, dibenso [a, h] anthracene and benso [g, h, i] perylene in aerosols by analysis PAHs using GC-MS. It is suggested that aerosols mainly come from vehicle exhaust and fly dust. Owing to the variation of molecular weight, PAHs separation occurs in the progress of migration and diffusion. By comparison, PAHs organic pollutant in monitoring region is much higher than the background.
