Low-cost air pollution sensors operated by trained citizen scientists provide an opportunity to fill this gap. We describe the development and implementation of an air pollution monitoring and community engagement plan in response to resident concerns regarding excessive smoke production from a neighborhood restaurant. Particulate matter (PM2.5) was measured using a low-cost, portable sensor. When cooking was taking place, the highest PM2.5 readings were within 50 m of the source (mean PM2.5 36.9 \u00b5g\/m3) versus greater than 50 m away (mean PM2.5 13.0 \u00b5g\/m3). Sharing results with local government officials did not result in any action to address the source of the smoke emissions, due to lack of jurisdiction. A review of air pollution regulations across the United States indicated that only seven states regulate food cookers and six states specifically exempted cookers from air pollution regulations. Concerns about the smoke were communicated with the restaurant owner who eventually changed the cooking fuel. Following this change, less smoke was observed from the restaurant and PM2.5 measurements were reduced to background levels. Although current environmental health regulations may not protect residents living near sources of food cooker-based sources of PM2.5, community engagement shows promise in addressing these emissions.<\/jats:p>","DOI":"10.3390\/air3030020","type":"journal-article","created":{"date-parts":[[2025,7,18]],"date-time":"2025-07-18T14:03:51Z","timestamp":1752847431000},"page":"20","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Excessive Smoke from a Neighborhood Restaurant Highlights Gaps in Air Pollution Enforcement: Citizen Science Observational Study"],"prefix":"10.3390","volume":"3","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1963-4006","authenticated-orcid":false,"given":"Nicholas C.","family":"Newman","sequence":"first","affiliation":[{"name":"Department of Pediatrics, College of Medicine, University of Cincinnati, Cincinnati, OH 45229, USA"},{"name":"Division of General and Community Pediatrics, Cincinnati Children\u2019s Hospital Medical Center, Cincinnati, OH 45229, USA"},{"name":"Department of Environmental and Public Health Sciences, College of Medicine, University of Cincinnati, Cincinnati, OH 45267, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Deborah","family":"Conradi","sequence":"additional","affiliation":[{"name":"Independent Researcher, Cincinnati, OH 45231, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2141-9033","authenticated-orcid":false,"given":"Alexander C.","family":"Mayer","sequence":"additional","affiliation":[{"name":"Department of Environmental and Public Health Sciences, College of Medicine, University of Cincinnati, Cincinnati, OH 45267, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-6896-2400","authenticated-orcid":false,"given":"Cole","family":"Simons","sequence":"additional","affiliation":[{"name":"College of Medicine, University of Cincinnati, Cincinnati, OH 45267, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ravi","family":"Newman","sequence":"additional","affiliation":[{"name":"Department of Political Science, College of Arts and Sciences, Ohio State University, Columbus, OH 43210, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Erin N.","family":"Haynes","sequence":"additional","affiliation":[{"name":"Department of Environmental and Public Health Sciences, College of Medicine, University of Cincinnati, Cincinnati, OH 45267, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,7,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"631","DOI":"10.1007\/s10653-015-9720-1","article-title":"Air pollution and public health: Emerging hazards and improved understanding of risk","volume":"37","author":"Kelly","year":"2015","journal-title":"Environ.
