公务机客舱微小气候及空气质量分析

Analysis of microclimate and air quality in business jet cabins

目的了解公务机客舱的卫生条件,加强对公务机的卫生检疫和监督。方法选取了具有代表性机型的公务机,分别在关舱前、平飞阶段、落地后开舱前3个阶段,对其客舱进行温度、相对湿度、风速、照度、噪音、一氧化碳(CO)、二氧化碳(CO2)、可吸入颗粒物、甲醛及细菌总数等10个指标的监测,根据GB9673-1996《中华人民共和国公共交通工具卫生标准》和GBT18883-2002《室内空气质量标准》进行评价。结果所有阶段的污染物指标(CO、CO2、可吸入颗粒物、甲醛及细菌总数)都达到国家标准,但是部分温度、相对湿度、照度和关舱前的风速和噪音指标超标。结论公务机客舱微小气候和空气质量状况良好,出入境检验检疫部门应进一步有针对性地加强卫生监督管理。

Objective To analyze sanitary conditions of business jet cabins, and to strengthen sanitary quarantine and supervision of the business jet cabins. Methods Business jets with representative models were chosen to be investigated. For the 3 stages of before, in and after flight, 10 indexes including air temperature, relative humidity,wind speed, illumination, noise, carbon monoxide（CO）, carbon dioxide（CO2）, inhalable particles, formaldehyde and bacteria count of the business jet cabins are monitored, and the measured data were evaluated according to the Hygienic Standard for Public Means of Transportation（GB9673-1996） and Indoor Air Quality Standard（GBT18883-2002）. Results All of the contamination indexes, such as CO, CO2, inhalable particles, formaldehyde and bacteria count, accord with national standards during 3 stages, while part of theindexes exceed the standard, such as air temperature, relative humidity, illumination, and the wind speed and noise before cabins are closed. Conclusion The microclimate and air quality of the business jet cabins are both in good condition, and the entry-exit inspection and quarantine departments should further strengthen the sanitary supervision and management in a targeted manner.
