摘要
比较了我国四大代表性城市北京、青岛、成都和广州的PAHs污染,主要从三个方面进行比较:多环芳烃的浓度分布状况、季节变化以及在不同功能区的浓度变化趋势。
Polycyclic aromatic hydrocarbons (PAHs) as one of important organic pollutants which are ubiquitous and dangerous in the atmosphere are studied for years to understand the status of occurrence and concentration of airborne PAHs. PAHs in aerosol of four representative cities as Beijing, Qingdao, Chengdu and Guangzhou are analyzed from three aspects which are the concentrations distribution, seasonal varieties and concentration change in different regions.
