Michigan EGLE's 2024 PM2.5 review found mobile sources were the largest single contributor at the Detroit-SW, Allen Park and Dearborn sites; it also noted ferrous metals, soil and dust, and possible bridge-construction influence at Detroit-SW.
Based on 2016–2021 source-apportionment data from three Wayne County sites; results are site- and study-period context, not current AQI or uniform conditions across Detroit.
The City of Detroit says it has installed seven fixed Teledyne T640x monitors across Detroit to measure PM2.5, PM10 and coarse particulate matter.
The city monitor network supplements other Detroit monitoring efforts and is not the provider for this page's current AQI.
US AQI condenses air quality into one value. On this page, it helps you quickly judge whether conditions look good, moderate or more polluted than usual.
Check the outdoor and running cards first. They combine AQI, particles, ozone, weather and other factors that can affect outdoor comfort.
The ventilation card considers AQI and pollutants such as particles, nitrogen dioxide and ozone. If values are elevated, a shorter opening or a later moment may be better.
Weather, emissions, ozone formation, particles and air flow can shift local conditions, so the next hours can differ from the current reading.
This page uses US AQI.
Current and hourly air-quality values are CAMS-based model estimates, not measurements from a local monitoring station. They may not reflect street-level conditions.
City Air Quality selects the active data package, combines weather and air-quality data, chooses the current or latest usable model value, and formats it for this page.
Each local statement is linked to a checked primary-authority source. A source check is editorial provenance and does not describe current-data freshness.
Local sources support the background claims below; they are not the source of the current data shown above unless explicitly stated otherwise.

PDF page 14, PM2.5 Compositional Analysis, summarizes the three-site study and reports mobile-source, ferrous-metal, soil/dust and possible Detroit-SW bridge-construction influences.
Applicability: Wayne County source-apportionment context based on 2016–2021 data from three sites; it does not identify the source of current conditions across Detroit.
Based on this source: Michigan EGLE's 2024 PM2.5 review found mobile sources were the largest single contributor at the Detroit-SW, Allen Park and Dearborn sites; it also noted ferrous metals, soil and dust, and possible bridge-construction influence at Detroit-SW.
City of Detroit
The City of Detroit Air Quality Center section states the number, instrument model, fixed deployment and particulate measurements.
Applicability: City-operated particulate-monitoring network that supplements state, county and community systems; it is separate from this page's model data.
