4th of July fireworks come with a dangerous side effect

FRESNO, Calif. (KFSN) -- Fourth of July fireworks will fill the Central Valley skies with more than just sparkling colors.

The lighting of fireworks according to officials with the San Joaquin Air Pollution Control District will cause microscopic particle levels to spike in the Valley as much as six times the acceptable mark

"A dense pollution from fireworks that will trail off in the wee hours of July fifth. You'll see some hays July 5th from fireworks," says Heather Heinks.
