无锡空港口岸航空器微小气候与空气质量分析

目的了解无锡空港口岸航空器客舱内微小气候与空气质量情况,为进一步提升卫生监督质量,保障国际旅行者身体健康提供科学依据。方法对深圳航空公司在无锡空港口岸执勤的航空器进行客舱内的微小气候与空气质量监测,并在载客量异同的情况下进行了空气质量状况对比研究。结果在一年的监测周期中,相对湿度合格率为87.5%,CO2浓度合格率为91.7%,细菌总数合格率为95.8%;航空器满员时CO2和细菌总数与空舱时监测值比较,差异具有统计学意义,(P<0.01),而和载客量约为50%时监测值比较,差异也有统计学意义(P<0.05)。结论无锡空港口岸国际通航航空器卫生状况良好,微小气候与空气质量评价指标大部分符合国家卫生标准,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。

Analysis of microclimate and air quality of aircrafts in Wuxi Airport

Objective To investigate the microclimate and air quality of aircrafts in Wuxi airport, and provide sci- entific base for optimizing public health supervision, so as to protect the health of international travellers. Methods Monitor the microclimate and air quality in the aircrafts of Shenzhen Airlines in Wuxi Airport and analysis the difference of the air quality when the passenger capacity is changed. Results During a one - year monitoring cy- cle, the qualified rate of relative humidity is 87.5% , the qualified rate of CO2 concentration is 91.7% , and the qualified rate of total bacterial count is 95.8%. Paired samples t - test showed the CO2 concentration is different when the passenger capacity is changed and the total bacterial count of air is different too. Conclusion The public hygienic status of microclimate and air quality of~ aircrafts in Wuxi airport is in good condition, most of the evalua- tion index is in line with national health standard, and the entry - exit inspection and quarantine departments should further strengthen supervision and management of public health.
