PM 2.5 -- airborne respirable particles 2.5 microns or
smaller have been elevated in several areas today in Michigan.

As of 6 PM, 24 hour averages exceed the threshold for
"unhealthy for sensitive groups" at Grand Rapids, Lansing,
Ypsilanti, Dearborn, Allen Park and Port Huron, with
a near miss at Kalamazoo.

For details, see

Today illustrates well that these airborne particles that
have significant health effects can occur on days when
ozone is not elevated over the ozone air quality standards.
