典型二次有机气溶胶危害性及环境监测技术研究进展

Hazards and Environmental Monitoring Technology Progress for Typical Secondary Organic Aerosols is Reviewed

二次有机气溶胶(SOA)是细颗粒物中重要组成成分,相比一次有机气溶胶(POA),SOA对环境、气候变化和人体健康有着更大的影响。国内外已经在城市、郊区和背景区域开展了SOA基础观测与研究工作,积累了丰富的基础数据,为掌握SOA演变机理及其影响因素奠定了坚实基础,但是,其研究主要局限于短期观测,对其具体发生条件、变化规律和重要演化过程及形成机理特征并未开展系统的观测与研究。为进一步改善空气质量,亟需长期开展高时间分辨率高物种分辨率的综合观测。

Secondary organic aerosol is an important composition of fine particulate matter, Comparing to primary organic aerosols, which has greater harm for the environment, climate change and human health. Much observation and research has been carried out in cities, suburbs, and background region at home and abroad, accumulated rich basic data, which laid a solid foundation for mastering the SOA evolution mechanism and influencing factors. However, the research mainly limited to the short-term observation, and did not systematically carry out on their specific conditions, changing law, important evolution process and formation mechanism. In order to further improving air quality, high-time-resolution and high-species- resolution comprehensive observation would be carried out in urgent.
