Abstract

Assessment of personal exposure to PM; 2.5; is critical for understanding intervention effectiveness and exposure-response relationships in household air pollution studies. In this pilot study, we compared PM; 2.5; concentrations obtained from two next-generation personal exposure monitors (the Enhanced Children MicroPEM or ECM; and the Ultrasonic Personal Air Sampler or UPAS) to those obtained with a traditional Triplex Cyclone and SKC Air Pump (a gravimetric cyclone/pump sampler). We co-located cyclone/pumps with an ECM and UPAS to obtain 24-hour kitchen concentrations and personal exposure measurements. We measured Spearmen correlations and evaluated agreement using the Bland-Altman method. We obtained 215 filters from 72 ECM and 71 UPAS co-locations. Overall, the ECM and the UPAS had similar correlation (ECM ρ = 0.91 vs UPAS ρ = 0.88) and agreement (ECM mean difference of 121.7 µg/m; 3; vs UPAS mean difference of 93.9 µg/m; 3; ) with overlapping confidence intervals when compared against the cyclone/pump. When adjusted for the limit of detection, agreement between the devices and the cyclone/pump was also similar for all samples (ECM mean difference of 68.8 µg/m; 3; vs UPAS mean difference of 65.4 µg/m; 3; ) and personal exposure samples (ECM mean difference of -3.8 µg/m; 3; vs UPAS mean difference of -12.9 µg/m; 3; ). Both the ECM and UPAS produced comparable measurements when compared against a cyclone/pump setup.
