Excessive Smoke from a Neighborhood Restaurant Highlights Gaps in Air Pollution Enforcement: Citizen Science...

Area of Science:

• Environmental Science
• Public Health
• Community-Based Participatory Research

Background:

• Regulatory air quality networks may miss localized pollution hotspots from sources like restaurants.
• Citizen science, using low-cost sensors, can supplement official monitoring and address community concerns.
• Restaurant emissions, particularly smoke, can impact local air quality and resident health.

Purpose of the Study:

• To develop and implement a community-driven air pollution monitoring plan.
• To assess particulate matter (PM$_{2.5}$) levels near a restaurant with reported smoke issues.
• To evaluate the effectiveness of community engagement in addressing local air pollution sources.

Main Methods:

• Deployment of low-cost, portable particulate matter (PM$_{2.5}$) sensors by citizen scientists.
• Spatial measurement of PM$_{2.5}$ concentrations at varying distances from a restaurant's emission source.
• Community engagement with residents, restaurant owners, and local government officials.

Main Results:

• Elevated PM$_{2.5}$ concentrations (mean 36.9 μg/m$^3$) were detected within 50 meters of the restaurant during cooking, compared to lower levels (mean 13.0 μg/m$^3$) further away.
• Local government intervention was limited due to jurisdictional issues regarding food cooker emissions.
• Restaurant owner voluntarily changed cooking fuel, resulting in reduced smoke and PM$_{2.5}$ levels.

Conclusions:

• Current regulations inadequately address air pollution from food cookers.
• Community engagement and citizen science monitoring can be effective strategies for mitigating localized air pollution.
• Low-cost sensors offer a viable method for residents to monitor and address environmental health concerns.
