Fine and coarse particulate mass samples were collected during baseball games with pyrotechnic displays and control games without displays. The average fine and coarse particulate masses were 173 and 141 mg/m, respectively, for the one-hour period immediately following the pyrotechnic displays. The particulate matter generated by the pyrotechnic displays was composed of the following elements (arranged from most to least abundant): K, S, Mg,Ti, Cl, Si, Ca, Al, Sr, V, Zn, Mn, and Pb. Although the average particulate mass concentrations were high during the first hour, the ventilation system reduced the concentrations by up to 41% during the second hour after the display.
在有烟火表演的棒球比赛以及无烟火表演的对照比赛期间采集了细颗粒物和粗颗粒物质量样本。烟火表演结束后的紧接着的一小时内，平均细颗粒物和粗颗粒物质量分别为173毫克/立方米和141毫克/立方米。烟火表演产生的颗粒物由以下元素组成（按含量从高到低排列）：钾、硫、镁、钛、氯、硅、钙、铝、锶、钒、锌、锰和铅。尽管在第一小时内平均颗粒物质量浓度很高，但通风系统在表演后的第二小时将浓度降低了多达41%。
