Abstract:Air pollution poses a significant threat to public health, with poor air quality linked to respiratory and cardiovascular diseases. Disadvantaged communities (DACs) are often disproportionately affected, leading to health disparities. Monitoring air quality is crucial to understanding these impacts and developing effective mitigation strategies. While traditional regulatory monitors provide important data, emerging air quality sensors (AQS) offer more localized information. This report examines the importance of monitoring air quality in communities, the categories and performance of AQS, and guidelines for selecting monitoring sites. DACs and Vulnerable Roadway Users (VRUs) experience higher exposure, emphasizing the need for equitable monitoring efforts. The use of AQS can enhance spatial resolution and community engagement. AQS categories include stationary, portable, and wearable sensors, each with unique advantages. While AQS accuracy varies, field testing and proper calibration are important. Guidelines for selecting monitoring sites include proximity to pollution sources, consideration of meteorological conditions, spatial coverage optimization, and equity concerns. The Environmental Protection Agency’s Enhanced Air Sensor Guidebook can be referenced to aid in sensor selection and usage. Monitoring air quality and using AQS strategically can empower communities, drive policy changes, and contribute to healthier, more equitable environments.
