Abstract

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/m . 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 NO 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.

摘要

我们回顾了 1967 年至 2019 年间发表的 47 篇报告商用飞机挥发性有机化合物(VOCs)测量的文献。我们将这些测量值与飞机客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。对于存在限值的 VOC 平均水平,除了苯的平均浓度为 5.9±5.5μg/m 3 外,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。除了建筑物中平均浓度为 12ppb 的 NO 外,半挥发性有机化合物(SVOCs)和其他污染物的浓度均未超过标准和指南。虽然重点是 VOCs,但我们还检索了其他表征客舱环境的参数数据。臭氧浓度平均比飞机推荐的上限低 38ppb。每人的室外空气供应率从 1.7 到 39.5L/s 不等,平均为 6.0±0.8L/s/人(中位数为 5.8L/s/人),高于商用飞机推荐的最低水平。二氧化碳浓度平均为 1315±232ppm,低于飞机允许的浓度,接近建筑物允许的浓度。测量的温度平均为 23.5±0.8°C,通常在避免热不适的推荐范围内。相对湿度平均为 16%±5%,低于建筑物推荐的湿度。
