An air quality advisory is in effect for West Michigan through Monday, July 14.
According to a statement released by Southeast Michigan Council of Governments (SEMCOG), this advisory is due to elevated levels for fine particulate matter (PM-2.5). The Michigan Department of Environment, Great Lakes, and Energy (EGLE) cites wildfire smoke originating from Canada.
EGLE noted that levels of particle pollution are expected to reach Unhealthy for Sensitive Groups (USG, Orange AQI) through all of Monday, July 14 in southern parts of Michigan.
Sensitive groups are encouraged to take precautions.
Air pollution cause
“Wildfire smoke from Canada continues to push into Michigan on Sunday, with additional plumes expected Monday,” said Stephanie Hengesbach, Meteorology Specialist, Air Quality Division, Michigan Department of Environment, Great Lakes, and Energy.
Increased fine particulate levels due to smoke were seen Sunday morning across the Upper Peninsula into the northern portion of the Lower Peninsula. The smoke continues to track east and south, expanding across the rest of the state and with additional plumes forecasted to move in on Monday.
Hengesbach said southern locations can expect levels of fine particulate in the USG to Moderate range.
EGLE recommends:
- When possible, avoid strenuous outdoor activities, especially those with heart disease and respiratory diseases like asthma.
- Monitor for symptoms such as wheezing, coughing, chest tightness, dizziness, or burning in nose, throat, and eyes.
- Reduce or eliminate activities that contribute to air pollution, such as:
- outdoor burning;
- use of residential wood burning devices.
- Keep windows closed overnight to prevent smoke from getting indoors and, if possible, run central air conditioning with MERV-13 or higher rated filters.
How air quality is measured
Air quality is an important measure identified in SEMCOG plans and programs for creating desirable communities, protecting public health, and maintaining a positive regional image for Southeast Michigan. In partnership with the Michigan Department of Environment, Great Lakes, and Energy (EGLE), SEMCOG is now implementing a two-tiered system of Air Quality Advisories and Air Quality Alerts.
This new system is based on the EPA’s U.S. Air Quality Index (AQI).
The AQI is a scale from 0 to 500 that indicates air pollution levels. Higher values mean higher pollution and more health risks. When AQI exceeds 100, it is unhealthy, starting with sensitive groups and worsening as it rises.
There are six categories, each with a color, to easily gauge the level of health concern in communities.
Air quality advisories/alerts information:
Air Quality Advisory: Issued when ground-level ozone, particulate matter (PM2.5) or both are expected to reach or exceed the Unhealthy for Sensitive Groups (USG) threshold. Those considered in the “USG” threshold include people with lung disease (such as asthma), children, older adults, people who are active outdoors (including outdoor workers), people with certain genetic variants, and people with diets limited in certain nutrients should reduce prolonged or heavy outdoor exertion.
This is aimed to provide awareness for poor air quality, encourage people to limit activities that contribute to poor air quality, and to alert those who are especially sensitive to poor air quality.
Air Quality Alert: Issued when Ozone, PM2.5, or both are expected to reach or exceed the Unhealthy threshold or worse. This alert indicates a higher level of concern as everyone, not just sensitive groups, can be affected by poor air quality.
