I know, it comes as a shock to me, too.

Detroit has seen an increase in PM 2.5 pollution in recent years, reflecting this national trend as well as the disproportionate harm that communities of color suffer from air pollution. These fine particulates are 30 times smaller than the width of a human hair and can travel deep into the lungs and bloodstream.

The 2024 report ranked the metro Detroit area 13th among the 25 cities most polluted by annual particulate matter. Grand Rapids was 25th among those most affected by ozone. […] Ozone pollution can cause respiratory problems and increase the frequency of asthma attacks, while PM 2.5 is linked to cardiopulmonary problems and premature mortality.

The report also notes that the Biden administration has made significant progress toward addressing air pollution recently by updating particle pollution standards, addressing leaks from oil and gas production facilities, and improving pollution standards for cars, trucks, and buses.
