Pistacia species grow in temperate regions, and are widespread in the Mediterranean area. Two species can be found in the Iberian Peninsula: Pistacia lentiscus L. and Pistacia terebinthus L. Airborne pollen from these species, recorded in some Spanish provinces, is regarded by some authors as potentially allergenic, and therefore should be of particular interest, given that these species are actually being introduced as ornamentals in parks and gardens. This paper deals with a study of daily and seasonal Pistacia airborne pollen counts in Córdoba city, analysed in parallel with field flowering phenology data. The study was carried out in Córdoba, using a volumetric Hirst-type sampler in accordance with Spanish Aerobiology Network guidelines. Phenological monitoring was performed weekly from January to May at 7 sites in the mountain areas north of Córdoba city. The Pistacia pollen season lasted an average of 41 days, from mid-March to end of April. Higher pollen counts were recorded in evening hours. The pollen index increased over the study period, and the pollen season coincided with phenological observations. Some airborne pollen grains were recorded once flowering had finished, due to re-suspension or transport from other locations. Pistacia pollen counts in Córdoba were low, but sufficient to identify seasonal and daily patterns. This pollen type should be taken into account in pollen calendars, in order to fully inform potential allergy-sufferers. The number of trees introduced as ornamentals should be carefully controlled, since widespread planting could increase airborne pollen levels.
黄连木属植物生长在温带地区，广泛分布于地中海地区。伊比利亚半岛上有两种黄连木：黄连木和黄连木。一些作者认为，这些物种在一些西班牙省份记录到的空气传播花粉具有潜在的致敏性，因此应该特别关注，因为这些物种实际上作为观赏植物被引入公园和花园。本文研究了科尔多瓦市空气中黄连木花粉的日变化和季节性变化，同时分析了实地开花物候学数据。该研究在科尔多瓦市进行，使用符合西班牙空气生物学网络指南的容量型赫氏采样器。从 1 月到 5 月，每周在科尔多瓦市北部山区的 7 个地点进行物候监测。黄连木花粉季节平均持续 41 天，从 3 月中旬到 4 月底。傍晚时花粉计数较高。花粉指数随研究期而增加，花粉季节与物候观测相吻合。由于再悬浮或从其他地方运输，一些空气传播花粉粒在开花结束后被记录到。科尔多瓦市的黄连木花粉计数较低，但足以确定季节性和日变化模式。这种花粉类型应在花粉历中考虑，以便充分告知潜在的过敏患者。应该仔细控制作为观赏植物引入的树木数量，因为广泛种植可能会增加空气中花粉的水平。
