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 understand the hygiene conditions of business jet cabin and to strengthen the health quarantine and supervision of business jet. Methods A representative business jet was selected to carry out temperature, relative humidity, wind speed, illumination, noise, carbon monoxide (CO), air temperature and air temperature in its cabin in three stages before shutting down, , Carbon dioxide (CO2), respirable particulate matter, formaldehyde and total bacteria and other 10 indicators of monitoring, according to GB9673-1996 “People’s Republic of China public transport health standards” and GBT18883-2002 “indoor air quality standards” for evaluation. Results The indicators of pollutants (CO, CO2, respirable particulate matter, formaldehyde and total bacteria) reached national standards at all stages, but some of the indicators of temperature, relative humidity, illuminance and wind speed and noise before shutting down exceeded the standard. Conclusions The microclimate and air quality of business jet cabin is in good condition. Entry-exit inspection and quarantine departments should further strengthen the hygiene supervision and management.
