The Poaceae family, including grasses, comprises several cosmopolitan and allergenic species. The aim of this study was to determine the correlations between Poaceae pollen and Phl p 5 allergen concentrations in two cities with different geographical and climatic properties in Turkey. Pollen were collected from Burkard traps in Ankara and Zonguldak. Phl p 5 sampling was carried out between March and October in both 2015 and 2016 using a BGI900 Cascade High Volume Air Sampler (900 L/min.). The concentrations of Phl p 5 were measured by the enzyme-linked immunosorbent assay (ELISA) technique. The annual sum of Poaceae pollen (pollen index) during 2015-2016 was 5454 in Ankara and 4142 in Zonguldak. The total Phl p 5 concentration was 1309 pg/m in Zonguldak, whereas it was 8181 pg/m in Ankara over 2 years. About 90% of the allergen was found in the fraction with particulate matter (PM) > 10 μm in both cities. It was found that the main meteorological parameter which affected pollen and Phl p 5 was temperature in both stations. Rainfall was also found to be important for Zonguldak, due to its climatic and geographic properties. Lastly, we suggest that the primary wind direction, which is from the south of Zonguldak, could have a 'drift effect' for allergens because of the airborne pollen concentrations and the dates on which the allergen is released into the atmosphere. The wind direction may be an important factor in the distribution of allergen and pollen grains in stations, especially those with a hilly topography.
禾本科植物包括草类，有几个世界性的和过敏原的物种。本研究的目的是确定在土耳其两个具有不同地理和气候特征的城市中禾本科花粉与 Phl p 5 过敏原浓度之间的相关性。花粉在安卡拉和宗古尔达克用 Burkard 陷阱收集。2015 年和 2016 年，在 3 月至 10 月期间，使用 BGI900 级联大容量空气采样器（900 L/min）进行 Phl p 5 采样。Phl p 5 的浓度通过酶联免疫吸附试验（ELISA）技术测量。2015-2016 年，安卡拉的禾本科花粉年总和（花粉指数）为 5454，宗古尔达克为 4142。2 年间，宗古尔达克的总 Phl p 5 浓度为 1309 pg/m，而安卡拉为 8181 pg/m。在这两个城市中，约 90%的过敏原存在于 PM>10 μm 的颗粒物质（PM）中。发现两个站中影响花粉和 Phl p 5 的主要气象参数是温度。由于气候和地理特性，降雨对宗古尔达克也很重要。最后，我们建议，由于空气中花粉浓度和过敏原释放到大气中的日期，主要来自宗古尔达克南部的风向可能对过敏原产生“漂移效应”。风向可能是过敏原和花粉粒在站中的分布的一个重要因素，特别是那些具有丘陵地形的站。
