Wildfire smoke

In recent years, Michigan has seen unprecedented levels of wildfire smoke drifting across its communities and much of the rest of the country.

In addition to pollutants like fine particulate matter carried in the smoke, there are gasses containing the chemicals that – when combined with sunlight – form ground-level ozone. These chemical reactions contribute to elevated ozone levels seen in areas across Michigan. It is important to take steps to protect yourself from wildfire smoke.

Answer your most common questions

We provide answers to frequently asked questions about how wildfire smoke impacts air quality in our communities

And most importantly: we issue advisories and alerts

An advisory is issued when levels of ozone or PM2.5 are expected to be “unhealthy for sensitive groups

Unhealthy air quality for sensitive groups - orange

An alert is issued when levels of ozone or PM2.5 are expected to be “unhealthy”, “very unhealthy” or “hazardous

Unhealthy air quality - red Very unhealthy air quality - purple Hazardous air quality - maroon

What Michigan is doing about Canadian wildfire pollution

There is nothing the state can do to reduce the pollutants from the fires drifting over from Canada.

However, state agencies, including EGLE, Health and Human Services, Natural Resources and Agriculture and Rural Development are working together to give Michiganders the latest information on how to be informed and protect yourself and your loved ones when air quality may be harmful.
