Platanus hispanica trees are considered an important source of airborne pollen allergens in many cities of Western Europe. As the prevalence of sensitization to this species is 8% to 9% in northwestern Spain, our objective was to propose models predicting both the onset of the pollen season and the mean daily pollen concentrations.
Airborne P. hispanica pollen was monitored from 1993 through 2002 with 2 Hirst volumetric spore traps in Ourense and Santiago de Compostela in northwestern Spain. The pollination start dates were determined and the data were fitted to predictive regression models, which were tested for the year 2002.
P. hispanica pollen is present in the atmosphere from March to April. The main pollination period is short with a mean duration of around 40 days. The mean maximum daily concentrations exceeded 100 pollen grains/m(3). As temperature is the parameter that most influences atmospheric pollen levels, this variable was chosen as the basis for models predicting both the onset of the pollen season and daily pollen concentrations. The predicted onset date was a few days later than the real start date in 2002. However, the model gave an accurate prediction of the mean daily pollen concentration.
The mean daily concentrations of P. hispanica pollen are high, and given the allergenic potential of this species, it should be taken into account as one of the most important local spring allergens. The weather-related models proposed help us to predict P. hispanica pollen concentrations in the atmosphere.
在西欧许多城市，西班牙悬铃木被视为空气中花粉过敏原的重要来源。由于在西班牙西北部对该物种的致敏率为8%至9%，我们的目标是建立预测花粉季节开始时间和每日平均花粉浓度的模型。
1993年至2002年期间，在西班牙西北部的奥伦塞和圣地亚哥 - 德孔波斯特拉，使用2台赫斯特容积式孢子捕捉器监测空气中的西班牙悬铃木花粉。确定授粉开始日期，并将数据拟合到预测回归模型中，对2002年的数据进行测试。
西班牙悬铃木花粉在3月至4月出现在大气中。主要授粉期较短，平均持续时间约为40天。每日平均最高浓度超过100粒花粉/立方米。由于温度是对大气花粉水平影响最大的参数，该变量被选作预测花粉季节开始时间和每日花粉浓度模型的基础。预测的开始日期比2002年的实际开始日期晚几天。然而，该模型对每日平均花粉浓度给出了准确的预测。
西班牙悬铃木花粉的每日平均浓度很高，鉴于该物种的致敏潜力，应将其视为当地最重要的春季过敏原之一。所提出的与天气相关的模型有助于我们预测大气中西班牙悬铃木花粉的浓度。
