IEPA Report Shows “Downward Trends or Stable Trends Well Below The Level Of The Standards” for Air Pollutants

The Illinois Environmental Protection Agency recently issued its 2009 Annual Air Quality Report, which presents data for the six criteria pollutants (those for which air quality standards have been developed – particulate matter (PM10 and PM2.5), ozone, sulfur dioxide, nitrogen dioxide, carbon monoxide, and lead) along with some heavy metals, nitrates, sulfates, volatile organic and toxic compounds.  Monitoring was conducted at over 80 different site locations collecting data from more than 200 instruments.

The report shows “downward trends or stable trends well below the level of the standards” set for the criteria pollutants: “Percentage changes over the ten year period 2000 – 2009 are as follows: Particulate Matter (PM10) 26 percent decrease, Particulate Matter (PM2.5) 21 percent decrease, Sulfur Dioxide 40 percent decrease, Nitrogen Dioxide 21 percent decrease, Carbon Monoxide 40 percent decrease, Lead 36 percent decrease, and Ozone 13 percent decrease.”  The report also shows a general trend toward decreasing emissions for stationary point sources.
