Professor David Y.H. Pui, from the University of Minnesota, will speak on "China: Sources, Effects, Mitigation, and Its Impact on China: Sources, Effects, Mitigation, and Its Impact on Energy Industry", in the Ian Ross Seminar Room, Ian Ross Building, at the Australian National University in Canberra, 2pm, 6 February 2014.
PM2.5 (Particulate Matter less
than 2.5 Am) was established by the U.S. Environmental Protection Agency
in 1997 as the standard method for sampling fine particles, because of
concern over the health effects of fine particles in the ambient
environment. The Particle Technology Laboratory (PTL) has developed many
instruments and samplers to perform atmospheric measurements, which
helped to establish the PM2.5 standard. The effects of PM2.5 pollutants
on the atmospheric visibility and human health will be addressed.
PM2.5 sources in China have been identified to come from pollutants from
coal burning (approx. 40%) and from vehicle emissions (approx. 25%).
The strategy for pollution control must be based on reducing the
pollutants from these two primary sources. Filtration is one of the
principal means to control PM2.5 pollutants. Baghouse filters are used
to reduce emissions from coal-fired power plants and Diesel and Gasoline
Particulate Filters (DPF and GPF) are used to reduce vehicle emissions.
The PM2.5 impact, both short-term and long-term, to the energy industry
will also be addressed. An integrative approach, from collaboration
among academia, government, and industries, can effectively manage and
mitigate the PM2.5 pollutants in China.
David Y. H. Pui, a Distinguished McKnight University Professor, is the
L.M. Fingerson/TSI Inc Chair in Mechanical Engineering and the Director
of the Particle Technology Laboratory and of the Center for Filtration
Research, University of Minnesota. He has a broad range of research
experience in aerosol science and technology and has over 230 journal
papers and 22 patents. He has developed/co-developed several widely
used commercial aerosol instruments. Dr. Pui is a fellow of the American
Society of Mechanical Engineers (ASME), and has received many awards,
including the Max Planck Research Award (1993), the Humboldt Research
Award for Senior U.S. Scientists (2000), the Fuchs Memorial Award
(2010)--the highest disciplinary award conferred jointly by the
American, German and Japanese Aerosol Associations, and the Einstein
Professorship Award (2013) by the Chinese Academy of Sciences (CAS). He
was a past President of the American Association for Aerosol Research
(AAAR) and of the International Aerosol Research Assembly (IARA)
consisting of 16 international aerosol associations.
