Precision and Accuracy of a Direct-Reading Miniaturized Monitor in PM_2.5 Exposure Assessment.

ABSTRACT: The aim of this study was to evaluate the precision, accuracy, practicality, and potential uses of a PM_2.5 miniaturized monitor (MM) in exposure assessment. These monitors (AirBeam, HabitatMap) were compared with the widely used direct-reading particulate matter monitors and a gravimetric reference method for PM_2.5. Instruments were tested during 20 monitoring sessions that were subdivided in two different seasons to evaluate the performance of sensors across various environmental and meteorological conditions. Measurements were performed at an urban background site in Como, Italy. To evaluate the performance of the instruments, different analyses were conducted on 8-h averaged PM_2.5 concentrations for comparison between direct-reading monitors and the grav
