在香港，许多人每天都长时间地坐在封闭的车辆里。然而，关于空调私家车的车内空气质量以及可能影响空气质量的汽车使用情况的数据相对有限。51辆汽车在日常旅行过程中接受了颗粒物(PM0.3和PM2.5)、总挥发性有机化合物(TVOCs)、一氧化碳(CO)、二氧化碳(CO2)、空气中细菌和真菌水平的测试。其中10辆车在发动机怠速时进一步检查了PM0.3、PM2.5、TVOCs、CO和CO2。总体而言，驾驶期间机舱内的PM2.5水平减少了加班时间，但PM0.3并未减少。在TVOCs方面，有24%的车辆超过香港环境保护署所订办公室和公众场所的室内空气质素建议水平。总挥发性有机化合物(TVOC)浓度与车龄呈正相关。所有车辆的一氧化碳(CO)水平都低于IAQ建议的水平，而96%的车辆超过了推荐的1000ppmv；16%的车辆>；5000ppmv。微生物数量相对较低。发动机怠速时TVOCs水平高于行驶时。虽然我们在车辆上的时间很短，但我们不应忽视暴露在高水平污染物中的潜在风险。
Many people spend lengthy periods each day in enclosed vehicles in Hong Kong. However, comparably limited data is available about in-cabin air quality in air-conditioned private vehicles, and the car usage that may affect the air quality. Fifty-one vehicles were tested for particulate matter (PM0.3 and PM2.5), total volatile organic compounds (TVOCs), carbon monoxide (CO), carbon dioxide (CO2), airborne bacteria, and fungi levels during their routine travel journey. Ten of these vehicles were further examined for PM0.3, PM2.5, TVOCs, CO, and CO2 during engine idling. In general, during driving PM2.5 levels in-cabin reduced overtime, but not PM0.3. For TVOCs, 24% vehicles exceeded the recommended Indoor Air Quality (IAQ) level in offices and public places set by the Hong Kong Environmental Protection Department. The total volatile organic compounds (TVOC) concentration positively correlated with the age of the vehicle. Carbon monoxide (CO) levels in all of the vehicles were lower than the IAQ recommendation, while 96% vehicles exceeded the recommended CO2 level of 1000 ppmv; 16% vehicles >5000 ppmv. Microbial counts were relatively low. TVOCs levels at idle engine were higher than that during driving. Although the time we spend in vehicles is short, the potential exposure to high levels of pollutants should not be overlooked.
