title: Effects of Indoor Pyrotechnic Displays on the Air Quality in the Houston Astrodome.
abstract: 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/m3, 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.
