Air Quality

As I clicked on the interactive world map of air quality, the first area that popped up was the United States. I began to scan across the nation in search of the worst air quality to find the cause and location of it. The only red hazardous tag that I saw was located in the Southwest corner of the nation in Riverside, California. After doing some research, I found that the local municipal Airport was causing the Hazard. Everything was normal on the charts except the PM2.5. That is what set off the hazard tag being measured at 830. All of the other sections of pollution and air measurement were normal including the ozone and nitrous oxide.
