Olea pollen is considered one of the most critical causes of respiratory allergic disease in the Mediterranean region, contributing to different symptoms in allergic sufferers. Due to the high increase in the prevalence of olive pollen caused by the expansion of cultivated areas especially in the Mediterranean region, the aim of this study was to examine the Olea pollen sampling efficiency between gravimetric and volumetric pollen traps over the period 2018-2022. Our data demonstrated that Olea pollen season start-date was generally recorded earlier with volumetric trap than shown with gravimetric method. Moreover, the peak dates occurred mainly in May for the years studied. Across the entire period, the greatest pollen concentrations were reached in the week 11th and >60 % of the total Olea pollen were already reached after the ninth week of sampling in 2020. In general, the evolution of pollen sampling for both methods demonstrates similar temporal development. Variations in the seasonal pollen integral could be attributed to the elevation above ground level at which the traps were placed, exposure to regional winds, the influence of long-range transported pollen and the mode of pollen transport. The findings indicate that the gravimetric method was equally practical as the volumetric method in estimating airborne pollen.
油橄榄花粉被认为是地中海地区引发呼吸道过敏疾病的最主要原因之一，可导致过敏患者出现不同的症状。由于橄榄花粉种植面积的扩大（尤其是在地中海地区），导致花粉的流行率显著增加，因此本研究旨在比较 2018-2022 年期间，重量法和容量法花粉收集器对油橄榄花粉的采样效率。我们的数据表明，与重量法相比，容量法记录的油橄榄花粉季节开始日期通常更早。此外，研究年份的高峰期主要出现在 5 月。在整个研究期间，2020 年第 11 周达到了最大的花粉浓度，第 9 周后已采集到超过 60%的总油橄榄花粉。总的来说，两种方法的花粉采样演变都呈现出相似的时间发展趋势。季节性花粉积分的变化可能归因于收集器的离地高度、暴露于区域风、远距离传输花粉的影响以及花粉传输方式。研究结果表明，重量法与容量法在估计空气传播花粉方面同样实用。
