The Preliminary Study on the Major Influencing Factors of Air Quality in Immigration Hall at Luohu Port

〔目的〕发现影响罗湖口岸出入境大厅空气质量的主要因素。〔方法〕2006年1月—2007年10月,在罗湖口岸4层出入境大厅各设3个空气质量监测点,对空气中甲醛、一氧化碳、二氧化碳、可吸入颗粒物含量每月进行1次监测,并对监测数据进行统计学分析。〔结果〕3楼大厅空气中甲醛和一氧化碳含量均高于其它楼层,3楼北侧空气中甲醛和一氧化碳含量均高于3楼其它位点;地库二氧化碳含量高于其他楼层。〔结论〕汽车尾气是造成罗湖口岸出入境大厅空气污染的主要因素。

Objective To find the major influencing factors of air quality in immigration hall at Luohu port. Method From January 2006 to October 2007, three monitoring sites were set in four immigration halls and the content of Formaldehyde, Carbon monoxide, Carbon dioxide, Respirable Particulate Matter were monitored once a month. Meanwhile, the monitoring data were analyzed. Result Formaldehyde and Carbon monoxide concentration in the air of the third floor were higher than those of other floors, the site of north of the third floor had the higher air concentration of Formaldehyde and Carbon monoxide than those of other sites in the third floor. The basement had the highest air concentration of Carbon dioxide. Conclusion Automobile exhaust is the major air pollution factors in immigration hall.
