Tests were conducted to determine the relationship between concentrations of airborne pollens and sampling time, using sequential rotoslide samplers at urban and rural locations. Short-period data showed an increase in variability with time between samples. Two-hour data showed a stronger trend for the first 12 hours but better agreement as the time between samples approached one day.
利用连续旋转玻片采样器在城市和农村地区进行了测试，以确定空气中花粉浓度与采样时间之间的关系。短期数据显示样本间的变异性随时间增加。两小时的数据在前12小时显示出更强的趋势，但随着样本间时间接近一天，一致性更好。
