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: 184-16 979 spores m(-3); total pollen: 0-6692 pollen m(-3); PM10: 6.70-65.38 microg m(-3); PM2.5: 5.04-45.02 microg 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 of fall. Our study concluded that several types of inhalable airborne fungi and pollen, particulate matter, and ozone could be positively correlated as a result of the atmospheric temperature influence.
在本研究中,我们考察了环境中可吸入空气中真菌和花粉的浓度与PM10、PM2.5、臭氧、有机碳、选定的痕量金属(镉、铜、铅和锌)、温度及相对湿度之间的关系。该数据库是在美国俄亥俄州辛辛那提连续两年收集的。除冬季月份外,所有环境变量的测量每周连续5天在同一地点进行。生物和非生物污染物的空气传播浓度范围如下:总真菌:184 - 16979个孢子/立方米;总花粉:0 - 6692个花粉/立方米;PM10:6.70 - 65.38微克/立方米;PM2.5:5.04 - 45.02微克/立方米;以及臭氧:2.54 - 64.17 ppb。在秋季和夏季发现总可吸入真菌和颗粒物的水平较高。相比之下,春季总花粉浓度呈现升高水平。臭氧的峰值浓度在夏季和秋季初被观测到。我们的研究得出结论,由于大气温度的影响,几种类型的可吸入空气中真菌和花粉、颗粒物及臭氧可能呈正相关。
