Abstract

Allergic diseases are a global health problem; their prevalence has increased in recent decades. The presence of allergenic airborne pollen is one of the main triggers of this disorder. For this reason, the first pollen calendar of Toluca City was developed. Daily and bihourly airborne pollen samplings with a Hirst-type Burkard Trap were performed from August 2009 to December 2013. Annual Pollen Integral (APIn), Main Pollen Season (MPS) and Diurnal Pattern (DP) were determined. Relationships with meteorological parameters were investigated. Tree pollen grain presented higher concentrations, with Cupressaceae as the most abundant taxon (52.6%), followed by Alnus sp. (13.3%), Pinaceae (7.3%), Fraxinus sp. (6.0%) and Quercus sp. (2.0%), which presented a definite seasonality. Urticaceae (3.7%) was the most abundant herbaceous pollen taxon registered. The DP obtained showed that pollen grains of most taxa are frequently found after midday and afternoon. Regression models showed the influence of environmental variables on all taxa. This study will allow us the enhancement of preventive actions and improvement of the regional design of patient tests.

墨西哥托卢卡市的空气花粉日历

过敏性疾病是一个全球性的健康问题;近几十年来，它们的流行率有所上升。空气中存在的致敏花粉是这种疾病的主要诱因之一。因此，托卢卡市的第一个花粉日历被开发出来。2009年8月至2013年12月，采用hirst型Burkard诱捕器对空气中花粉进行每日和每两小时采样。测定了年花粉积分(APIn)、主要花粉季节(MPS)和日格局(DP)。研究了与气象参数的关系。树木花粉粒含量较高，以柏科(52.6%)最多，其次为桤木(13.3%)、松科(7.3%)、白蜡属(6.0%)和栎属(2.0%)，具有一定的季节性。荨麻科(3.7%)是最丰富的草本花粉分类群。结果表明，大多数分类群的花粉粒多出现在中午和下午。回归模型显示了环境变量对各类群的影响。这项研究将使我们能够加强预防措施和改进患者检查的区域设计。
