Hairdressers are exposed to particulate matter (PM), a known air pollutant linked to adverse health effects. Still, studies on occupational PM exposures in hair salons are sparse. We characterized indoor air PM concentrations in three salons primarily serving an African/African American (AA) clientele, and three Dominican salons primarily serving a Latino clientele. We also assessed the performance of low-cost sensors (uRAD, Flow, AirVisual) by comparing them to high-end sensors (DustTrak) to conduct air monitoring in each salon over 3 days to quantify work shift concentrations of PM , respirable PM (RPM), and PM . We observed high spatial and temporal variability in 30-min time-weighted average (TWA) RPM concentrations (0.18-5518 μg/m ). Readings for the uRAD and AirVisual sensors were highly correlated with the DustTrak (R = 0.90-0.99). RPM 8-hour TWAs ranged from 18 to 383 µg/m for AA salons, and 9-2115 µg/m for Dominican salons. Upper 95th percentiles of daily RPM exposures ranged from 439 to 2669 µg/m . The overall range of 30-min TWA PM and PM concentrations was 0.13-5497 and 0.36-,541 μg/m , respectively. Findings suggest that hairdressers could be overexposed to RPM during an 8-hour shift. Additional comprehensive monitoring studies are warranted to further characterize temporal and spatial variability of PM exposures in this understudied occupational population.
美发师会接触到颗粒物（PM），这是一种已知的空气污染物，与不良健康影响有关。然而，关于美发沙龙中职业性PM暴露的研究却很少。我们对三家主要服务于非洲裔/非裔美国人（AA）顾客的美发沙龙和三家主要服务于拉丁裔顾客的多米尼加美发沙龙的室内空气PM浓度进行了特征描述。我们还通过将低成本传感器（uRAD、Flow、AirVisual）与高端传感器（DustTrak）进行比较，评估了它们的性能，以便在每家沙龙进行为期3天的空气监测，以量化工作班次期间PM、可吸入PM（RPM）和PM的浓度。我们观察到30分钟时间加权平均（TWA）RPM浓度存在很大的空间和时间变异性（0.18 - 5518μg/m³）。uRAD和AirVisual传感器的读数与DustTrak高度相关（R² = 0.90 - 0.99）。AA美发沙龙的RPM 8小时TWA范围为18至383μg/m³，多米尼加美发沙龙为9至211μg/m³¹⁵。每日RPM暴露的第95百分位数范围为439至2669μg/m³。30分钟TWA PM和PM浓度的总体范围分别为0.13至5497μg/m³和0.36至541μg/m³。研究结果表明，美发师在8小时轮班期间可能会过度暴露于RPM。有必要进行更多全面的监测研究，以进一步描述这一研究不足的职业人群中PM暴露的时间和空间变异性。
