We reviewed 47 documents published 1967–2019 that reported measurements of volatile organic compounds (VOCs) on commercial aircraft. We compared the measurements with the air quality standards and guidelines for aircraft cabins and in some cases buildings. Average levels of VOCs for which limits exist were lower than the permissible levels except for benzene with average concentration at 5.9 ± 5.5 μg/m³. Toluene, benzene, ethylbenzene, formaldehyde, acetaldehyde, limonene, nonanal, hexanal, decanal, octanal, acetic acid, acetone, ethanol, butanal, acrolein, isoprene and menthol were the most frequently measured compounds. The concentrations of semi-volatile organic compounds (SVOCs) and other contaminants did not exceed standards and guidelines in buildings except for the average NO₂ concentration at 12 ppb. Although the focus was on VOCs, we also retrieved the data on other parameters characterizing cabin environment. Ozone concentration averaged 38 ppb below the upper limit recommended for aircraft. The outdoor air supply rate ranged from 1.7 to 39.5 L/s per person and averaged 6.0 ± 0.8 L/s/p (median 5.8 L/s/p), higher than the minimum level recommended for commercial aircraft. Carbon dioxide concentration averaged 1315 ± 232 ppm, lower than what is permitted in aircraft and close to what is permitted in buildings. Measured temperatures averaged 23.5 ± 0.8°C and were generally within the ranges recommended for avoiding thermal discomfort. Relative humidity averaged 16% ± 5%, lower than what is recommended in buildings.

无烟商业航班的机舱空气质量：对已发布的空气污染物数据的审查


我们回顾了 1967 年至 2019 年发表的 47 份文件，这些文件报告了商用飞机上挥发性有机化合物 (VOC) 的测量结果。我们将测量结果与飞机机舱和某些情况下建筑物的空气质量标准和指南进行了比较。除苯平均浓度为 5.9 ± 5.5 μg/m ³外，存在限值的 VOC 平均含量均低于允许水平。甲苯、苯、乙苯、甲醛、乙醛、柠檬烯、壬醛、己醛、癸醛、辛醛、乙酸、丙酮、乙醇、丁醛、丙烯醛、异戊二烯和薄荷醇是最常测量的化合物。除平均 NO ₂浓度为 12 ppb 外，半挥发性有机化合物 (SVOC) 和其他污染物的浓度未超过建筑物中的标准和指南。虽然重点是挥发性有机化合物，但我们还检索了表征客舱环境的其他参数的数据。臭氧浓度平均比建议的飞机上限低 38 ppb。室外空气供应量为每人 1.7 至 39.5 L/s，平均为 6.0 ± 0.8 L/s/p（中位数为 5.8 L/s/p），高于商用飞机建议的最低水平。二氧化碳浓度平均为 1315 ± 232 ppm，低于飞机允许的浓度，接近建筑物允许的浓度。测量的平均温度为 23.5 ± 0.8°C，通常在避免热不适的建议范围内。相对湿度平均为 16% ± 5%，低于建筑物建议的湿度。
