我们回顾了1967-2019年发布的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。除平均浓度为5.9±5.5μg/m3的苯外,存在限值的VOC的平均水平低于允许水平。甲苯,苯,乙苯,甲醛,乙醛,柠檬烯,非肛门,己醛,decanal,octanal,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。除了平均NO2浓度为12ppb外,建筑物中半挥发性有机化合物(SVOC)和其他污染物的浓度均未超过标准和准则。虽然重点是挥发性有机化合物,我们还检索了表征机舱环境的其他参数的数据。臭氧浓度平均低于飞机建议的上限38ppb。室外空气供应速率范围为每人1.7至39.5L/s,平均为6.0±0.8L/s/p(中位数为5.8L/s/p),高于商用飞机推荐的最低水平。二氧化碳浓度平均为1315±232ppm,低于飞机允许的水平,接近建筑物允许的水平。测得的温度平均为23.5±0.8°C,通常在建议避免热不适的范围内。相对湿度平均为16%±5%,低于建筑物中的建议。
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.
