------------------------------------------------------------------------- Enviro-Mich message from Christopher Graham ------------------------------------------------------------------------- Hi, All --

It's because we have been out of the weather stream, and within an air inversion (cold air above holding stagnant warm -- dirty -- air, below).  I assume most of our particulate matter is floating up here from Chicago and environs, and Illinois power plants.

Chris.

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.

http://www.deq.state.mi.us/aqi/PM.asp

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.

http://www.deq.state.mi.us/aqi/
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.

http://www.deq.state.mi.us/aqi/PM.asp

As of 1 PM Saturday:

Port Huron  105.2
Dearborn  93.8
Allen Park  84.2
Ypsilanti  64.3
Flint   58.7
Saginaw   56.9
Lansing  55.1
Houghton Lake  43.9
Grand Rapids  75.2
Kalamazoo    58.7
Holland   46.3
