DNR Says Several Factors Could Combine To Make For Poor Air Quality Over The Next Several Days
(Des Moines)-- The Iowa Department of Natural Resources says a combination of clear skies, hot temperatures and high humidity could bring poor air quality to most of the state starting Friday and continuing through the upcoming weekend.
The agency recommends those with respiratory or heart disease, especially children and the elderly, to limit prolonged outdoor exertion, especially during the afternoon and evening Friday and Saturday.
Todd Russell oversees air quality monitoring for the DNR. He says hot, sunny conditions favor the formation of photochemical smog in which volatile organic compounds react with nitrogen oxide, which produces ozone. The increased ozone can make it difficult to breathe for those suffering from respiratory or heart conditions.
