Airborne pollens are one of the common causative and triggering agents of respiratory allergy in a changing planetary environment. A growing number of people worldwide are contracting allergic diseases caused by pollens. The seasonal variations in pollens have occurred everywhere and the sensitization rate to pollens has increased in children as well as in adults. Moreover, allergenic plants, such as ragweed and Japanese hop, grow in soil damaged by human's activities and deforestation with air pollution. It is impossible to avoid plants that cause allergies, because pollens can travel many kilometers in the breeze or wind. Hence, it is essential to survey and forecast pollens for the management of pollen allergy. Weather conditions may alter pollen concentrations. A number of studies have shown that increases in CO concentration and atmospheric temperature raise pollen concentration. Hence most of the studies on the impact of climate change on aeroallergens must include the amount and allergenicity of pollens. It is yet unknown whether complex interactions with pollens, meteorological variables, and air pollutants in the changing environment. Considering the effect of climate change on the long-term trends in pollen levels and emerging viral infection, it is crucial to forecast and eliminate the associated risk for human health in future and take appropriate measures to reduce it.
在不断变化的全球环境中，空气传播的花粉是引发呼吸道过敏的常见病因和触发因素之一。全球越来越多的人感染了由花粉引起的过敏性疾病。花粉的季节性变化随处可见，儿童和成人对花粉的致敏率都有所上升。此外，豚草和葎草等致敏植物生长在因人类活动、森林砍伐以及空气污染而受损的土壤中。由于花粉可在微风或风中传播数公里，因此无法避免接触引发过敏的植物。因此，对花粉进行监测和预测对于花粉过敏的管理至关重要。天气条件可能会改变花粉浓度。大量研究表明，二氧化碳浓度和大气温度的升高会提高花粉浓度。因此，大多数关于气候变化对气传变应原影响的研究必须涵盖花粉的数量和致敏性。在不断变化的环境中，花粉、气象变量和空气污染物之间复杂的相互作用尚不清楚。考虑到气候变化对花粉水平长期趋势和新出现的病毒感染的影响，预测并消除未来对人类健康的相关风险并采取适当措施加以降低至关重要。
