The occurrence of symptoms in pollen allergy patients in urban areas may be affected by local environmental factors such as sources of pollution, natural and ornamental vegetation, local architecture impeding dispersion, etc. The aim of this study was to analyse the frequency of sensitization in pollen allergy patients and the relationship with antihistamine sales. For this study, a large number of clinical records, together with pharmaceutical and pollen data, were collected between 1999 and 2001 in the city of Córdoba, in the south of the Iberian Peninsula. Differences were observed in the symptoms suffered by pollen allergy patients in different areas of the city due to varying local emission of both biological and non-biological particles. Temporal distribution of symptoms over the three study years was influenced by meteorological factors, especially rainfall patterns; higher water supply to plants was associated with increased airborne pollen concentrations. Air pollution might be one of the main factors affecting the distribution of pollen allergy patients within the city. Recent years have seen a worsening of symptoms and increased sensitization to urban species such as plane-trees.
城市地区花粉过敏患者症状的出现可能会受到当地环境因素的影响，如污染源、自然和观赏植被、阻碍花粉扩散的当地建筑等。本研究的目的是分析花粉过敏患者的致敏频率以及与抗组胺药销售的关系。在这项研究中，1999年至2001年期间在伊比利亚半岛南部的科尔多瓦市收集了大量临床记录以及药物和花粉数据。由于城市不同区域生物和非生物颗粒的局部排放不同，观察到花粉过敏患者在不同区域所患症状存在差异。在这三年的研究期间，症状的时间分布受气象因素影响，尤其是降雨模式；植物水分供应增加与空气中花粉浓度升高有关。空气污染可能是影响花粉过敏患者在城市内分布的主要因素之一。近年来，症状有所恶化，对悬铃木等城市物种的致敏性增加。
