摘要
目的调查分析太原市秋季气传致敏花粉的种类、含量与不同楼层之间的关系。方法在2008年8月1日至9月30日,在太原市中心同一地区采用曝片法收集花粉,将取样器分别安放于四面通风的4、7、17层楼顶,对比观察不同楼层的花粉含量。结果按花粉含量多少排序,4层(12米)>7层(21米)>17层(51米);对不同楼层花粉含量做分析,4层与7层花粉数目比较,P>0.05;4层与17层、7层与17层比较,P<0.05;4、7层花粉种类相同,17层花粉种类减少。结论17层(51米)的花粉含量、种类较4层、7层明显减少,住高层住宅可减少花粉的吸入量。
Objective To explore the relationship between the type and content of autumn airborne pollen and floors in Taiyuan. Methods Airborne pollens were continuously collected using an exposed glass method at three collecting spots in the same district in the centre of the city from August 1st to September 30th in 2008. The samples were separately placed on the well-ventilated building roofs of the 4th,7th and 17th floors. Results The samples were sequenced according to the pollen content:the 4th floor (12 meters)the 7th floor(21 meters)the 17th floor (51 meters). The content of airborne pollen was not statistically different between 4-floored buildings and 7-floored buildings (P〉0.05) while it was significantly lower in 17-floored buildings than in 4-floored buildings and 7-floored buildings (P〈0.05). The genera of airborne pollens of 4-floored buildings and 7-floored buildings were approximately the same,while of 17-floored buildings were reduced. Conclusion The type and content of airborne pollens on the 17^th (51 meters) floor are obviously reduced compared with those of the 4th floor and the 7th floor. High-rise residential living can reduce the amount of pollen inhalation.
