摘要
通过 1 995年和 1 998年澳门大气气溶胶中多环芳烃分析表明 ,1 998年的有机污染程度是 1 995年的 1 3 6～ 4 3 6倍 ,大气气溶胶中多环芳烃白天高于夜间 ,说明主要污染物为居民的工作、生活、商业、交通所排放。澳门商业交通功能区有机毒害污染较为严重 ,苯并 (a)芘和苯并(a)蒽分别为 1 56～ 8 1 0ng/m3和 0 85～ 4 68ng/m3。
It is shown that organic contaminative grade in 1998 is 1\^36 to 4\^36 times than 1995 by analyzing PAHs in aerosols at Macao in 1995 and 1998.It is suggested that PAHs concentrations in aerosols at day are higher than those at night,with day and night diversity of resident emitting from working,living,commerce and traffic.It is believed that commercial and traffic function areas are serious pollution sites because the concentrations of benzo(a)pyrene and benzo(a)anthracene are 1\^56～8\^10 ng/m 3 and 0\^85～4\^68 ng/m 3 in aerosols,respectively.
