INTRODUCTION Data about the occurrence of airborne pollen enables the creation of pollen calendars with an approximation of flowering periods for the most common allergenic plant species in a specific area. The aim of this work is to provide pollen calendar for each of the seven monitoring regions of Portugal based on 15 years of airborne sampling, in order to chart the seasonal behaviour of the main allergenic pollen types. MATERIAL AND METHODS Airborne pollen monitoring (2002-2017) was carried out by the Portuguese Aerobiology Network (RPA), using Hirst-type volumetric spore traps, following well-established guidelines. RESULTS A total of 14 airborne pollen types were recorded at RPA monitoring stations, of which 64.2% belong to trees, 28.5% to herbs and 7.1% to weeds. The airborne pollen spectrum is dominated by important allergenic pollen types such as Poaceae, Quercus spp., Urticaceae and Cupressaceae. The average pollen index was 42.557 in mainland Portugal and 3.818 in the Islands. There was an increased trend in the airborne pollen levels over the years, namely in Coimbra, Évora and Porto, compared to the remaining regions. CONCLUSION This report provides accessible information about the main allergenic airborne pollen types occurring in the course of the year. The pollen calendars charted for each Portuguese region showed that the occurrence of most allergenic taxa was centred from March to July. Pollen peak concentrations were detected earlier in the Centre and Lisbon and Tagus Valley regions, and later in the remaining regions.

葡萄牙的机载花粉日历:一项为期15年的调查(2002年至2017年)。

引言关于特定区域中最常见的致敏植物物种,通过空气传播花粉的发生数据可以创建花粉日历,其中花期近似于开花期。这项工作的目的是基于15年的机载采样,为葡萄牙的七个监测区域中的每个区域提供花粉日历,以便绘制出主要的致敏花粉类型的季节性行为图。材料与方法空中传粉监测(2002-2017)是由葡萄牙航空生物学网(RPA)使用的是赫斯特(Hirst)型体积孢子阱,并遵循公认的准则。结果RPA监测站共记录了14种空气传播的花粉类型,其中64.2%属于树木,28.5%属于草药,7.1%属于杂草。空气中的花粉光谱主要由重要的致敏花粉类型决定,例如禾本科,栎属,荨麻科和柏科。葡萄牙大陆的平均花粉指数为42.557,而群岛则为3.818。与其余地区相比,多年来,即科英布拉,埃武拉和波尔图的空气中花粉水平呈上升趋势。结论本报告提供了有关一年中发生的主要过敏性空气传播花粉类型的无障碍信息。针对每个葡萄牙区域绘制的花粉日历显示,大多数致敏分类单元的发生集中在3月至7月。在中心,里斯本和塔霍河谷地区较早时检测到花粉峰值浓度,在其余区域中较晚检测到。葡萄牙大陆的平均花粉指数为42.557,而群岛则为3.818。与其余地区相比,多年来,即科英布拉,埃武拉和波尔图的空气中花粉水平呈上升趋势。结论本报告提供了有关一年中发生的主要过敏性空气传播花粉类型的无障碍信息。针对每个葡萄牙区域绘制的花粉日历显示,大多数致敏分类单元的发生集中在3月至7月。在中心,里斯本和塔霍河谷地区较早时检测到花粉峰值浓度,在其余区域中较晚检测到。葡萄牙大陆和岛屿的平均花粉指数为42.557,岛屿为3.818。与其余地区相比,多年来,即科英布拉,埃武拉和波尔图的空气中花粉水平呈上升趋势。结论本报告提供了有关一年中发生的主要过敏性空气传播花粉类型的无障碍信息。针对每个葡萄牙区域绘制的花粉日历显示,大多数致敏分类单元的发生集中在3月至7月。在中心,里斯本和塔霍河谷地区较早时检测到花粉峰值浓度,在其余区域中较晚检测到。结论本报告提供了有关一年中发生的主要过敏性空气传播花粉类型的无障碍信息。针对每个葡萄牙区域绘制的花粉日历显示,大多数致敏分类单元的发生集中在3月至7月。在中心,里斯本和塔霍河谷地区较早时检测到花粉峰值浓度,在其余区域中较晚检测到。结论本报告提供了有关一年中发生的主要过敏性空气传播花粉类型的无障碍信息。针对每个葡萄牙区域绘制的花粉日历显示,大多数致敏分类单元的发生集中在3月至7月。在中心,里斯本和塔霍河谷地区较早时检测到花粉峰值浓度,在其余区域中较晚检测到。
