Posted Updated

RALEIGH — On hot, stuffy days like these the sun actslike an oven, cooking the chemicals emitted from cars and factories tocreate a nasty batch of unhealthy air. That's how ozone is created andhigh levels of ozone can have deadly consequences.

Winds from Wednesday afternoon thunderstorms helped to dissipate muchof the smog that had built up in the Triangle, so no official smogalert was in effect. Tuesday, however, the Triangle surpassed federalhealth standards for smog for the first time in three years. If thoseconditions return dangerous levels could return.

Air Quality Expert Ellis Cowling says smog can pose serious healthrisks.

State health officials warn that, until the air starts moving again, elderly people, children, and people with lung or heart ailments shouldtry to stay inside.

With each additional car on our highways come additional threats toour air quality. That's why scientists have been studying the air alongTriangle highways.

Mark Smith of the North Carolina Division of Air Quality says crewshave been out on Triangle roads measuring ozone levels.

An effort to find out what Triangle traffic are putting into the air..it's making more ozone smog everyday.

Cowling says there will be more smog-related illness in this area astraffic continues to increase.

Smog can seriously damage the body. It could make breathingdifficult, aggravate asthma, and inflame the lungs.

Ozone is a good thing in the upper atmosphere, where it blocks harmfulrays from the sun. The problems arise when it drifts down into the loweratmosphere.
