ST. PAUL, Minn. (AP) -- Minnesota health officials have extended an air pollution warning in the Minneapolis-St. Paul area through Tuesday due to expected high levels of ozone.
The state pollution control agency says ozone is expected to hit levels that are risky for sensitive groups. That means children, the elderly, people with respiratory conditions and anyone headed outside for heavy work or play.
The MPCA says outdoor activities should be postponed or done in the morning, when ozone levels are lower.
The agency says people can help during air-quality advisories by reducing car trips, using gas-powered equipment less and holding off on using paints and solvents.
