5 takeaways from EGLE's 2019 Air Quality Annual Report
January 20, 2021
The year 2019 was another year of overall air quality improvement across the Michigan, according to the latest Annual Air Quality Report released by the Michigan Department of Environment, Great Lakes, and Energy's (EGLE) Air Quality Division.
The 2019 Annual Air Quality Report provides information about specific pollutants, including those with National Ambient Air Quality Standards (NAAQS) and toxic air contaminants, air quality trends and an overview of the air monitoring network.
Here are five takeaways from the report:
1. All areas of the state meet national health safety standards for carbon monoxide, lead, nitrogen dioxide and particulate matter.
2. Some areas of the state do not meet national standards for sulfur dioxide and ozone, but levels of those pollutants are still decreasing.
3. Air quality in Michigan is generally in the Good or Moderate range, with occasional periods where it is unhealthy for sensitive groups. But, rarely does air quality reach unhealthy levels for everyone.
4. EGLE has a network of more than 40 air monitoring sites that check for one or more pollutants. Nineteen are in the Detroit-Ann Arbor area with the rest throughout Michigan, including the Upper Peninsula.
5. The weather plays a significant role in air quality and can either help increase or decrease the amount of pollution in the air. High temperatures, sun, and days with more daylight hours are conducive to ozone formation, whereas rain tends to wash pollutants out of the air.
EGLE's Air Quality Division offers three ways for the public to stay connected about air quality:
1. Current data for Michigan can be found on MIAir.
2. Air Quality alerts can be delivered directly to email by signing up for the Michigan EnviroFlash program.
3. EGLE supplies Michigan air monitoring data to AIRNow, the U.S. Environmental Protection Agency's nationwide air quality mapping system.
