职业性气溶胶暴露是许多工业部门已知的危害，可能是几种呼吸系统疾病的风险因素。在这项研究中，对低成本的气溶胶传感器Dylos DC1700和一种改进型的Dylos犹他改进型Dylos传感器（UMDS）进行了实验室评估，以评估传感器在高浓度呼吸性和可吸入性粉尘采样方面的效率，这在职业环境中是最常见的。在一个低速风洞中使用3个umds测量粉尘浓度，并配备气溶胶光谱仪（Grimm 1.109）和重力可吸入和可吸入采样器。共进行了10项测试，包括5种不同浓度和2种不同的测试气溶胶，亚利桑那州道路粉尘和氧化铝。对于亚利桑那州的道路粉尘，总颗粒数在光谱仪和UMDS之间有很强的相关性，决定系数（R2）在0.86 ~ 0.92之间。用UMDS测量的颗粒数浓度转换为质量，并与重力收集的可吸入性和可呼吸性粉尘有关。与可吸入取样器相比，UMDS小仓（即所有颗粒）的R2为0.86-0.92，与可吸入取样器相比，减去小仓（即只有最小颗粒）的大仓的R2为0.93 - 0.997。使用氧化铝的测试表明，在所有比较中，这种关系都要低得多。此外，对所有仪器内部变异性的评估是一致的，但仪器之间的变异性表明，每台仪器都需要自己的校准方程来产生准确的暴露估计。总的来说，UMDS似乎可以作为一种低成本的工具来估计许多工作场所的可吸入和可吸入浓度。未来的研究将集中于在职业环境中部署UMDS网络。
Exposure to occupational aerosols are a known hazard in many industry sectors and can be a risk factor for several respiratory diseases. In this study, a laboratory evaluation of low-cost aerosol sensors, the Dylos DC1700 and a modified Dylos known as the Utah Modified Dylos Sensor (UMDS), was performed to assess the sensors’ efficiency in sampling respirable and inhalable dust at high concentrations, which are most common in occupational settings. Dust concentrations were measured in a low-speed wind tunnel with 3 UMDSs, collocated with an aerosol spectrometer (Grimm 1.109) and gravimetric respirable and inhalable samplers. A total of 10 tests consisting of 5 different concentrations and 2 different test aerosols, Arizona road dust and aluminum oxide, were conducted. For the Arizona road dust, total particle count was strongly related between the spectrometer and the UMDS with a coefficient of determination (R2) between 0.86–0.92. Particle count concentrations measured with the UMDS were converted to mass and also were related with gravimetrically collected inhalable and respirable dust. The UMDS small bin (i.e., all particles) compared to the inhalable sampler yielded a R2 of 0.86–0.92 and the large bin subtracted from the small bin (i.e., only the smallest particles) compared to the respirable sampler yielded an R2 of 0.93 to 0.997. Tests with the aluminum oxide demonstrated a substantially lower relationship across all comparisons. Further, assessment of intra-instrument variability was consistent for all instruments but inter-instrument variability indicated that each instrument requires its own calibration equation to yield accurate exposure estimates. Overall, it appears that the UMDS can be used as a low-cost tool to estimate respirable and inhalable concentrations found in many workplaces. Future studies will focus on deployment of a UMDS network in an occupational setting.
