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/m³ vs UPAS mean difference of 93.9 µg/m³) 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/m³ vs UPAS mean difference of 65.4 µg/m³) and personal exposure samples (ECM mean difference of −3.8 µg/m³ vs UPAS mean difference of −12.9 µg/m³). Both the ECM and UPAS produced comparable measurements when compared against a cyclone/pump setup.

比较下一代便携式污染监测仪，以测量秘鲁普诺市家庭空气污染对PM2.5的暴露。

对个人暴露于PM _2.5的评估对于了解家庭空气污染研究中的干预效果和暴露-反应关系至关重要。在这项初步研究中，我们比较了PM _2.5从两个下一代个人暴露监测器（Enhanced Children MicroPEM或ECM；和超声个人空气采样器或UPAS）获得的浓度，与传统三重旋风除尘器和SKC气泵（重力旋风/泵采样器）获得的浓度相同。我们与ECM和UPAS一起安装了旋风除尘器/水泵，以获得24小时厨房集中度和个人暴露测量。我们测量了Spearmen相关性，并使用Bland-Altman方法评估了一致性。我们从72个ECM和71个UPAS主机位获得了215个过滤器。总体而言，ECM和UPAS具有相似的相关性（ECMρ= 0.91 vs UPASρ= 0.88）和一致性（ECM平均差异为121.7 µg / m ³与UPAS平均差异为93.9 µg / m ³）与旋风除尘器/水泵相比时具有重叠的置信区间。调整检测限后，所有样品（ECM平均差异为68.8 µg / m ³与UPAS平均差异为65.4 µg / m ³）和个人暴露样品（ECM）的设备与旋风分离器/泵之间的一致性也相似。平均差异为-3.8 µg / m ³与UPAS平均差异为-12.9 µg / m ³）。与旋风除尘器/泵的设置相比，ECM和UPAS均可产生可比的测量结果。
