On October 22, 2022, 50 Detroit community residents, faculty, staff and students from the University of Michigan School of Public Health toured southwest Detroit to experience firsthand the ways that public policies and decision-making shape access to clean air for Detroit residents, with implications for health inequities. The tour of southwest Detroit highlighted the area’s history, including that of the Delray community, home to successive waves of immigrants from Hungary, Malta, Mexico and many southern US states.

Houses close to the Gordie Howe International Bridge site.Also located in the area are multiple industrial sources of air pollutants, including the Marathon Oil Refinery, and other local land uses that draw heavy diesel truck traffic on residential streets, where they pass by homes, schools and health care facilities. In addition, I-75 passes through southwest Detroit en route to the Ambassador Bridge, bringing approximately 10,000 trucks per day carrying over $122 billion worth of imports and exports between the United States and Canada. Southwest Detroit is also the site of the Gordie Howe International Bridge (GHIB), currently under construction. 

Together, these land uses benefit commerce and industry across the US and Canada. However, the human health costs associated with these land uses are disproportionately borne by residents of southwest Detroit, who experience high levels of diesel particulate from truck exhaust and associated health risks, including cardiovascular risk and rates of asthma that are nearly double those for the state of Michigan as a whole.

Featured speakers included:

  • Simone Sagovac, Community Organizer for Southwest Detroit Community Benefits Coalition
  • Cindy Gamboa, Community Organizer for Detroit Hispanic Development Corporation
  • Felix Valbuena, Chief Executive Officer for Community Health and Social Services
  • Stuart Batterman, professor of Environmental Health Sciences, Michigan Public Health
  • Amy J. Schulz, professor of Health Behavior and Health Education, Michigan Public Health


Amy Schulz speaking with sponsorAs part of the tour, participants considered land use decision-making in Michigan and questions about who benefits from and who is harmed by those land use decisions. They heard from community residents who have led efforts to reduce adverse health impacts associated with the proposed bridge. Those efforts, detailed in an article led by Michigan Public Health alumnae Natalie Sampson and community organizer Simone Sagovac, included the communities’ request for a Health Impact Assessment (HIA) of the GHIB. The HIA was conducted in 2016-2018 by community residents in conjunction with researchers from University of Michigan-Dearborn and Michigan Public Health. Findings included a very strong sense of community among residents of the area in which the GHIB would be located, many of whom would be displaced by bridge construction, and disproportionate rates of asthma among residents living near heavily trafficked roads in the area. A second wave of the HIA is planned for 2023, and will include monitoring of changes in air pollution at the base of the bridge as well as interviews with community residents.

Communities experiencing disproportionate environmental exposures and associated health outcomes have long drawn attention to the role of racism in shaping those risks. More recently, public health researchers have begun to examine racism as a fundamental driver of racial inequities in health. As of September 2022, 256 declarations naming racism as a public health issue had been passed at the state, county and municipal level across 39 states. Those declarations importantly draw attention to structural racism—discrimination built into social, economic and environmental policies—as it drives persistent racial inequities across multiple health outcomes, including maternal, infant and COVID-19 mortality. These policies include those that shape access to clean air, including decisions about land uses that emit air pollutants and the communities in which they will be located. The use of explicitly anti-racist approaches to research, including community-based participatory research, is central to understanding and addressing the health implications of those decisions, and to public health efforts to promote health equity.
