Fine Particulate Matter Forum

Date and Time: Thursday, August 10, 3:40 – 5:40 pm
Location: Conference Theater

Chair: Heejung Jung (University of California, Riverside)

For tens of millions people living in urban areas, air pollution poses of serious adverse health effects such as respiratory diseases, lung cancer, heart disease, premature death, and others. In 2016 more than 80 percent of people living in urban areas were exposed to air quality levels exceeding the World Health Organization (WHO) air quality guidelines. The largest source of urban air pollution is often motor vehicles, but the contribution of other industrial combustion processes is also important. Particulate matters, volatile organic compounds and oxides of nitrogen from the combustion sources are involved with the formation of fine particulate matters and that result in air pollution.

The appearance of displeasing hazy skyline and the formation of unhealthy smog are hardly a new aspect of Korea’s urban atmosphere.  Despite the implementation of a range of policies and management efforts by the Korean government for decades, the reduction of fine particulate matters is still desirable.  Policies and programs should be developed systematically and revised periodically to understand emission sources and characteristics comprehensively, to identify mitigation opportunities, and to track the emission reduction and air quality improvement.

As a benchmark, U.S. has successfully reduced fine particulate matters and improved air quality past 50 years starting with Clean Air Act in 1963 and subsequent legislations. Four panel members were invited from U.S. institutions and agencies to share their knowledge on primary emissions, secondary formation, air quality modeling, and policy.
