Outdoor asthma triggers can’t always be seen, but they may result in mild to severe asthma attacks for people with asthma. Severe asthma attacks can lead to hospitalization and can even be life-threatening (1).

Clean air advocate Langston Verdin knew that heavy concentrations of airborne industrial, commercial, and vehicle pollutants were present in some neighborhoods in Milwaukee, Wisconsin, and that they were likely leading to increased asthma prevalence and asthma attacks in vulnerable populations in these neighborhoods.

“We have a highway that runs right through Milwaukee and many of the poor health outcomes follow that highway, especially when it relates to respiratory health issues,” Langston said. He made it a mission to help activate asthma awareness throughout his community, setting out to uncover the sources of asthma triggers, turning to a proven, practical solution to help amplify his voice: data collected with IQAir air quality monitors.

A focus on asthma in children

Langston first got involved in community clean air activism in 2019 as the Director of Strategic Partnerships at the Children’s Health Alliance of Wisconsin. He managed the Asthma Coalition, a subgroup of the Alliance.

The Asthma Coalition focused on forming partnerships with schools, childcare centers, and other sites, teaching best practices to help mitigate asthma’s causes and effects.

Langston knew that accessing better data would help confirm elevated air pollution levels in vulnerable and affected communities.

Why air quality monitoring matters

Langston also knew that identifying source contaminants was only one piece of the air quality puzzle.

Air quality monitoring is a powerful tool that can raise community awareness about unhealthy concentrations of airborne pollutants. Residents can be alerted when poor air quality poses a health threat. Air quality monitoring provides communities with a real-time view of air quality degradation, empowering people to react by closing windows, wearing masks, or running an air purifier.

The call to action

Langston was inspired to become an air quality data contributor when he watched an environmental catastrophe unfolding half a world away. He was watching a news report on Australia’s extreme and record-breaking bushfires of 2019 and 2020. In the report, he saw that air quality was being mapped using the IQAir AirVisual map.

He remembers the impact of seeing the situation unfold: “I was intrigued by being able to see the air quality and how bad it was getting in real time.”

Clean air for kids

While working with the Asthma Coalition, Langston prioritized working with schools and childcare centers because “the younger you are, the more vulnerable you are to poor air quality.”

Research bears this out. According to a review of studies published in The Journal of Allergy and Clinical Immunology, asthma isn’t evenly distributed. Children in crowded urban environments are more likely to develop asthma and experience greater asthma-induced morbidity (2).

What triggers asthma?

Knowing what triggers asthma and when asthma triggers are in the air can help reduce attacks and save lives. While asthma triggers can vary between children, asthma triggers can include (3):

• exposure to particle pollutants like tobacco smoke or vehicle exhaust
• viral infections
• allergens such as dust mites, pet dander, mold, and pollen
• physical exercise
• changes in weather

Student development and education can also be impacted by asthma. Asthma is both a leading cause of chronic illness and school absenteeism in the United States (4)(5).

From awareness to action

Working with the Coalition, while educating school administrators about how to make their site more asthma-friendly, Langston was able to ignite action further to team up.

Langston has been particularly concerned with areas on the northwest of Milwaukee, a predominantly African American community, and the near south side, a largely Hispanic community. African American and Hispanic communities, especially in Milwaukee, have been identified as carrying the highest incidents of childhood asthma prevalence in the state (6).

Air quality monitoring gives those Milwaukee communities a real time view of air quality degradation in the community.

Broadening the project’s scope

As the project progressed, Langston felt that a broader coalition of clean air activists was needed to maximize its effectiveness and potential. That was when he founded the MKE FreshAir Collective.

The MKE FreshAir Collective own and maintain outdoor air quality monitors in five different Milwaukee neighborhoods:

• Harambee/Brewers Hill
• Near Westside
• Riverwest
• Silver Spring
• Washington Heights

There are more on the way.

Milwaukee air quality monitoring: what’s next

Currently employed with the City of Milwaukee Health Department, Langston continues to take an active role in community health at his workplace. One of his areas of interest at the Health Department is utilizing a U.S. Centers for Disease Control and Prevention (CDC) grant to monitor and clean the air in Milwaukee’s homeless shelters. But most of his air quality activism continues through the MKE FreshAir Collective.

It is his intention to establish a non-profit, to align his energies more closely on air pollution data collection and source mitigation, as well as collaborating with other organizations.

“We've got a lot of partners in the Milwaukee area who are passionate about a lot of this work,” Langston said.

He believes that every school and childcare center would benefit from air quality monitoring.

Langston continues to make connections, including working with the University of Wisconsin Madison where he will be consulting on a NASA-funded study researching real-time, community-level nitrogen dioxide emissions.

The takeaway

Langston’s activism and dedication to improving Milwaukee air quality provides a significant benefit to his community. Schools, daycare centers, and citizens who download a free app to monitor their air quality receive alerts when pollutants and asthma triggers are a threat.

Setting up a network of air quality monitors is a great goal – and so is monitoring air quality at school sites and in your own neighborhood. As Langston has demonstrated, anyone with the passion to protect their community’s air quality can become an air quality data contributor.

As Langston put it, air quality monitoring “creates a more robust system of knowledge so that everyone can be informed about how air quality is influencing our individual lives, our families, and our communities.”
