城市中生长的许多观赏植物具有相当大的致敏潜力，并对过敏患者构成风险。这些物种包括悬铃木属的成员，或伦敦悬铃木，这是越来越普遍的一些南欧城市。对空气中花粉浓度的分析可以评估生物空气质量，并提供有关当地植被分布的信息。本研究的目的是分析在西班牙中部每年悬铃木花粉浓度的趋势，并确定在何种程度上，他们与该物种在城市绿色空间的存在。研究结果指出，悬铃木数量的增加与年度花粉指数和过敏症患者处于危险中的天数的增加之间存在相关性。分析表明，在城市绿色空间的致敏性观赏植物的多样性和丰富度的变化可能占这些物种的空气传播花粉的动态和行为的趋势。在这类研究中获得的结果应反映在城市绿地管理计划中，以减少致敏负荷，从而减少接触致敏花粉并改善这些空间的空气质量。
Many ornamental species growing in cities have considerable allergenic potential and pose a risk to allergy sufferers. Such species include members of the genus Platanus, or London plane tree, which is increasingly prevalent in a number of southern European cities. Analysis of airborne pollen concentrations enables biological air quality to be assessed, and also provides information on the local distribution of vegetation. The aim of this study was to analyze trends in annual Platanus pollen concentrations in central Spain and to determine the extent to which they are linked to the presence of this species in urban green spaces. The results point to a correlation between the growing number of plane trees and an increase both in the annual pollen index and in the number of days on which allergy sufferers are at risk. Analysis suggests that variations in the diversity and abundance of allergenic ornamental species in urban green spaces may account for the trends observed in the dynamics and behavior of airborne pollen from these species. The results obtained in studies of this kind should be reflected in urban green-space management plans, in order to decrease the allergenic load and thus both reduce exposure to allergenic pollen and improve air quality in these spaces.
