Extreme Heat and Air Quality: Community Leader Perspectives on Information Barriers and Opportunities in Two Environmental Justice Communities.

Extreme heat and air pollution exposure are leading causes of adverse cardiorespiratory health outcomes. Exposure reduction strategies are often focused at the local level. This study examined critical challenges community leaders face in understanding and sharing environmental exposure and health information. We conducted interviews with 19 community leaders of two urban environmental justice communities in Massachusetts, United States. Using directed content analysis, we examined air quality and heat perceptions, information and data resources, and barriers to understanding and communicating relevant local information. Participants shared concerns about both poor air quality and extreme heat. They also expressed the opinion that exposure risk information about these topics is siloed; heat and air quality data can be hard to access, interpret, and effectively communicate with community members. Solutions recommended by participants included community engagement, open-data portals, and creative science communication. Increasing sustainable collaborations among academic, government, healthcare, and nonprofit sectors is recommended.
