The prevalence of allergic diseases has markedly increased in the last decades. It is therefore important to assess the distribution of airborne pollen, the most important aeroallergen, for allergic disease prevention and control.
To identify the species and quantity of airborne pollens, and observe their distribution characteristics in Shanghai, using gravitational (Durham Sampler) and volumetric (Rotorod Sampler 40) methods simultaneously. In addition, the correlation between both methods was analyzed to provide effective preventive measures for pollen-sensitized individuals.
Pollen counts were monitored in the same area from November 1, 2009 to October 31, 2010 by samplers set at the same height and site. Pollen concentrations as well as any association between the two methods were determined.
Two pollen concentration peaks in Shanghai were observed from March to May (spring) and September to October (autumn). In spring, tree pollen was the main species, with a predominance of Broussonetia. In autumn, grass pollen predominated, with mostly Humulus. Thirty-two species were identified by both gravitational and volumetric methods. Five and seven additional species were identified exclusively by the gravitational and volumetric methods, respectively. Pollen counts obtained from both devices were significantly correlated (P<0.05).
Two methods were used simultaneously for the first time to monitor pollen counts in central urban Shanghai, showing two annual peaks. Broussonetia and Humulus were the predominant spring and autumn pollens, respectively. Pollen counts obtained by both methods were clearly correlated. Regional airborne pollen monitoring offers preventive measures for sensitized individuals and provides useful clinical information.
在过去几十年中，过敏性疾病的患病率显著增加。因此，评估空气传播花粉（最重要的空气过敏原）的分布对于过敏性疾病的预防和控制非常重要。
同时使用重力（达勒姆采样器）和容积（Rotorod 采样器 40）方法来识别空气中花粉的种类和数量，并观察其在上海的分布特征。此外，还分析了两种方法之间的相关性，以为花粉致敏个体提供有效的预防措施。
从 2009 年 11 月 1 日至 2010 年 10 月 31 日，在同一高度和地点设置采样器，同时监测花粉计数。确定了花粉浓度以及两种方法之间的任何关联。
在上海观察到两个花粉浓度高峰，分别出现在 3 月至 5 月（春季）和 9 月至 10 月（秋季）。春季以树木花粉为主，优势种为朴树。秋季以草花粉为主，主要为葎草。通过重力和容积两种方法鉴定出 32 种花粉。通过重力和容积方法分别单独鉴定出 5 种和 7 种额外的花粉。两种设备获得的花粉计数明显相关（P<0.05）。
首次同时使用两种方法监测上海市中心城区的花粉计数，显示出两个年度高峰。朴树和葎草分别是春季和秋季的主要花粉。两种方法获得的花粉计数明显相关。区域性空气传播花粉监测为致敏个体提供了预防措施，并提供了有用的临床信息。
