On November 12-14, 2008, the California Air Resources Board and
the South Coast Air Quality Management District are
co-sponsoring a 3-day course on the successful application of
diesel particulate filter systems to diesel engines.  The course
will also cover various research into ultrafine particles (less
than 0.1 micron in diameter) in ambient air and the health risks
they pose along with coarse particles (PM10) or fine particles
(PM2.5).   For additional information, please go to:
