Speaker Abstract

Online Monitoring Technology and Application for Air Pollution

The formation, transformation, transport and evolution process of air pollution has obvious temporal and spatial correlation. Research and development of rapid, real-time and dynamic monitoring technology which can be applied to multi-component pollutants has become a major topic in this field. Because of the advantages of non-contact, non-sampling, high sensitivity and wide range detection, the monitoring technology based on the principle of spectroscopy has become one of the main development directions. By studying the interaction of light and environmental material, the database of the spectral characteristic and the spectrum quantitative analysis algorithm have been developed. Combined with the engineering technology, air pollution monitoring systems have been developed on DOAS, TDLAS, LIF, LIDAR techniques. Application demonstrations have been carried out in many cities, like Beijing, Shanghai, Guangzhou, Chongqing Nanjing and so on.
