General Info

Research is indicating that ultrafine particles (less than 0.1 micron in diameter) may be more harmful to health than either PM10 or PM2.5.  These findings could affect future air quality standards, engine designs, fuels and emission control technologies.The South Coast Air Quality Management District conducted a conference April 30 through May 2, 2006 at which health researchers, government policy makers, engine manufacturers, emission control manufacturers, and technology experts joined in lively and informative discussions of what needs to be done to reduce this currently-unregulated air pollutant.  The conference had more than 500 attendees.

As part of the conference program, the SCAQMD established an Ultrafine Particle Graduate Student Research Competition.  Graduate students throughout the United States were invited to submit summaries of their ultrafine particle research projects.  The projects could cover a wide range of categories, including particle formation, sampling, measurement, health effects, control strategies, and regulatory policy issues.  The submittals were judged by a panel of independent air pollution scientists.  Winners were selected based on originality, scientific merit, relevance to the field, and quality of the writing.
