I Love Fireworks

I love watching fireworks! Since air quality is an area of interest I had to check the pollution levels around Utah from the last week. Over the last few nights you see a several-hour increase in PM 2.5 which is due to fireworks. There are very high levels in Salt Lake County on the night of the 4th due to the many large firework shows. Several nights before the 4th had high levels from other city and residential fireworks (I imagine the large city firework shows has a bigger impact than residential fireworks, but I wonder if levels have been higher since areal fireworks were legalized a few years ago). Utah County saw the highest levels on the night of July 2nd. This was the night of the Stadium of Fire.
