July 4th was a polluter

Health authorities say the night sky over Lincoln on July Fourth was filled with more than just loud bangs and pretty colors. It was heavy with fireworks pollution.

Rick Thorson is environmental health supervisor for air quality at the city-county health department. He says the air didn't start clearing until 2 a.m. or so. He said Tuesday that the humidity and lack of wind made conditions ideal for keeping the polluted air low.

Thorson says the short stay for the bad air wouldn't have affected most people, but it could have irritated asthmatic conditions for some.
