The allergenic capacity of Olea europaea L. pollen is very important in several cities of the southern Iberian Peninsula, producing most pollinoses diagnosed in these cities. We have carried out a study on the annual, daily and diurnal variations in pollen from O. europaea in the atmosphere of Granada (Spain) during 4 consecutive years. Samplings were carried out with the aid of a Burkard spore trap. Very low levels of Olea pollen grains were first detected in the atmosphere from the end of April. Pollen levels peaked in May and June, and started to decrease from the last days of June and in July. Pollen in the atmosphere is related to meteorological parameters: temperature has a positive influence on pollinization and rainfall produces a negative effect. The diurnal variation pattern of pollen grain concentrations was quite homogeneous throughout the study, featuring an important increase around midday and a moderate decrease in the first hours of the morning and in the late evening.
在伊比利亚半岛南部的几个城市，油橄榄（Olea europaea L.）花粉的致敏能力非常重要，这些城市中诊断出的大多数花粉症都是由其引起的。我们连续4年对西班牙格拉纳达市大气中油橄榄花粉的年度、每日和昼夜变化进行了研究。采样借助Burkard孢子捕捉器进行。4月底首次在大气中检测到极低水平的油橄榄花粉粒。花粉水平在5月和6月达到峰值，6月最后几天和7月开始下降。大气中的花粉与气象参数有关：温度对授粉有积极影响，降雨则产生负面影响。在整个研究过程中，花粉粒浓度的昼夜变化模式相当一致，中午左右有显著增加，清晨和傍晚时分则有适度下降。
