If you listened to the TV weatherman on Friday predicting that
our current air pollution episode would improve on Saturday,
you wouldn't know it by looking at air monitoring data today on
Saturday.

Michigan's PM 2.5 episode has gotten worse overnight.
Today's episode is likely record breaking PM 2.5 air pollution since monitoring
first began in Michigan in year 2001, at least for Southeastern
Michigan and for Grand Rapids.


PM 2.5 pollution consists of very fine particulate matter that
is 2.5 microns or less.    For health effects information, see:
http://www.airnow.gov/particle/cover.html

All of the real time PM 2.5 monitoring stations in Michigan are
recording higher PM 2.5 air pollution today than yesterday.

Except for Seney National Wildlife Refuge in the Upper Peninsula,
all of the real time PM 2.5 air monitoring stations in the state
are reporting either "unhealthy" or "unhealthy for sensitive groups"
as of 12 noon Saturday.    The worst stations yesterday have gotten
much worse.

Note that the stations showing green for the air quality index
don't have PM 2.5 real time reporting monitors so that regional SE
Michigan PM 2.5 air quality should be judged by the Port Huron,
Dearborn, Allen Park and Ypsilanti PM 2.5 reporting stations.

For the last 24 hours, Port Huron, MI is the most PM 2.5 polluted
place in the United States.

Grand Rapids, Dearborn, Port Huron
and Allen Park are showing as "unhealthy" and the rest of the
real time PM 2.5 stations in MIchigan are showing 'unhealthy
for sensitive groups"  all the way up to Houghton Lake.

"Unhealthy for sensitive groups" begins at 40.5 micrograms per
cubic meter on the 24 hour average and "unhealthy" begins at
65.5 micrograms per cubic meter on the 24 hour average.

Allen Park  84.2
Ypsilanti  64.3
Flint   58.7
Saginaw   56.9
Lansing  55.1
Houghton Lake  43.9
Grand Rapids  75.2
