Residential PM Measured in 50 Homes Using Low‐cost Monitors over Two Heating Seasons in Rochester, NY

Heating appliances using wood and wood products for combustion are a major source of airborne PM and related pollutants during the heating season in Rochester, NY (Wang et al., 2012). Although most regulatory short-term PM monitoring is based on 24-h integrated measurements in relatively few locations, health outcomes may be triggered by increases in PM concentrations in the previous few hours (e.g., Gardner et al., 2014), and PM concentrations can vary greatly across an urban area (Zikova et al., 2017a). Temporally and spatially resolved estimates of PM exposure to wood smoke and other sources are needed to understand how health outcomes are associated with increases in PM concentration a few hours later.
