在这项研究中，我们研究了环境空气中可吸入真菌和花粉浓度与PM10、PM2.5、臭氧、有机碳和选定的痕量金属(镉、铜、铅和锌)之间的关系。温度。和相对湿度。该数据库是在美国俄亥俄州辛辛那提连续两年收集的。除冬季外，每周连续5天在同一地点进行所有环境变量的测量，空气中生物和非生物污染物的浓度范围为：真菌总数：184-16979孢子m(3)：总花粉：0-6692花粉m(3)。PM10：6.70-65.38微克m(-3)，PM2.5：5.04-45.02微克(-3)，臭氧：2.54-64.17 ppb。秋季和夏季的总可吸入真菌和颗粒物水平较高。相比之下，总花粉浓度在春季表现出较高的水平，臭氧浓度的峰值出现在夏季和初秋。我们的研究得出结论，几种类型的可吸入空气真菌和花粉。颗粒物，与臭氧呈正相关，是大气温度影响的结果。(C)2005爱思唯尔有限公司。保留所有权利。
In this study, we have examined the relationships between the concentrations of ambient inhalable airborne fungi and pollen with PM10, PM2.5, ozone, organic carbon, selected trace metals (cadmium, copper, lead, and Zinc). temperature. and relative humidity. The database was collected in Cincinnati, Ohio, USA, during two consecutive years. Measurements of all environmental variables were performed at the same site continuously 5 days a week except during winter months, The airborne concentrations of biological and non-biological pollutants ranged as follows: total fungi: 184-16979 spores m (3): total pollen: 0-6692 pollen m (3). PM10: 6.70-65.38 mu g m(-3), PM2.5: 5.04-45.02 mu g m(-3) and ozone: 2.54-64.17 ppb. Higher levels of total inhalable fungi and particulate matter were found during fall and summer months. In contrast, total pollen concentration showed elevated levels in spring, Peak concentrations of ozone were observed during summer and beginning or fall. Our study Concluded that several types of inhalable airborne fungi and pollen. particulate matter, and ozone could be positively correlated is a result of the atmospheric temperature influence.
