Using low-cost sensors and GPS to assess spatiotemporal variations in personal exposure to PM2.5 in the Washington State Twin Registry
Epidemiological studies typically rely on exposure assessments based on ambient PM2.5 concentrations at participants’ home addresses. However, these approaches neglect personal exposures indoors and across different non-residential microenvironments. To address this problem, our study combined low-cost sensors and GPS to conduct two-week personal PM2.5 monitoring in 168 adults recruited from the Washington State Twin Registry between 2018 […]
