Humans spend approximately 90% of their time indoors, impacting their own air quality through occupancy and activities. Human VOC emissions indoors from exercise are still relatively uncertain, and questions remain about emissions from chlorine-based cleaners. To investigate these and other issues, the ATHLETic center study of Indoor Chemistry (ATHLETIC) campaign was conducted in the weight room of the Dal Ward Athletic Center at the University of Colorado Boulder. Using a Vocus Proton-Transfer-Reaction Time-of-Flight Mass Spectrometer (Vocus PTR-TOF), an Aerodyne Gas Chromatograph (GC), an Iodide-Chemical Ionization Time-of-Flight Mass Spectrometer (I-CIMS), and Picarro cavity ringdown spectrometers, we alternated measurements between the weight room and supply air, allowing for determination of VOC, NH₃, H₂O, and CO₂ emission rates per person (emission factors). Human-derived emission factors were higher than previous studies of measuring indoor air quality in rooms with individuals at rest and correlated with increased CO₂ emission factors. Emission factors from personal care products (PCPs) were consistent with previous studies and typically decreased throughout the day. In addition, N-chloraldimines were observed in the gas phase after the exercise equipment was cleaned with a dichlor solution. The chloraldimines likely originated from reactions of free amino acids with HOCl on gym surfaces.

某大学体育中心运动和应用氯基清洁​​产品产生的挥发性有机化合物的定量和来源表征

人类大约 90% 的时间都在室内度过，通过居住和活动影响他们自己的空气质量。人体运动产生的室内 VOC 排放量仍然相对不确定，而氯基清洁剂的排放量仍然存在疑问。为了调查这些和其他问题，体育运动中心的室内化学研究 (ATHLETIC) 活动在科罗拉多大学博尔德分校 Dal Ward 体育中心的举重室进行。使用 Vocus 质子转移反应飞行时间质谱仪 (Vocus PTR-TOF)、Aerodyne 气相色谱仪 (GC)、碘化物-化学电离飞行时间质谱仪 (I-CIMS) 和 Picarro腔衰荡光谱仪，我们在重量室和供应空气之间交替测量，允许测定 VOC、NH ₃、H₂ O 和 CO ₂每人排放率（排放因子）。人为排放因子高于先前在个人休息时测量室内空气质量的研究，并与 CO ₂排放因子增加相关。个人护理产品 (PCP) 的排放因子与之前的研究一致，并且通常全天都在下降。此外，在用二氯溶液清洁运动器材后，在气相中观察到 N-氯醛亚胺。氯醛亚胺可能源自游离氨基酸与健身房表面上的 HOCl 反应。
