OBJECTIVES
To evaluate the monthly variation in the airborne (1→3)-β-D-glucan level throughout one year and its relationship with climatic factors (temperature, relative humidity, wind speed, hours of daylight, cloud cover, and pollen counts).
METHODS
A total of 106 samples were collected using a two-stage cyclone sampler at five outdoor sampling locations (on top of 5 university buildings). The kinetic limulus amebocyte lysate assay was used to obtain (1→3)-β-D-glucan levels.
RESULTS
Airborne (1→3)-β-D-glucan levels were significantly higher in the spring, particularly in April, and temperature was significantly related to (1→3)-β-D-glucan levels (r =0.339, p<0.05).
CONCLUSIONS
(1→3)-β-D-glucan levels may be highest in the spring, and outdoor temperature may influence (1→3)-β-D-glucan levels.
目的
评估全年空气中（1→3）-β-D-葡聚糖水平的月度变化及其与气候因素（温度、相对湿度、风速、日照时长、云量和花粉计数）的关系。
方法
使用两级旋风式采样器在五个室外采样地点（5所大学建筑的顶部）共采集了106个样本。采用动态鲎试剂法获得（1→3）-β-D-葡聚糖水平。
结果
空气中（1→3）-β-D-葡聚糖水平在春季显著较高，尤其是在4月，且温度与（1→3）-β-D-葡聚糖水平显著相关（r = 0.339，p<0.05）。
结论
（1→3）-β-D-葡聚糖水平可能在春季最高，室外温度可能影响（1→3）-β-D-葡聚糖水平。
