Environmental officials are warning that air pollution will spike in the Chicago area because of high temperatures and fireworks displays.

Officials say levels of ground-level ozone and fine particles are expected to be high enough to affect people with lung and heart conditions.

Sensitive people are advised to limit outdoor activity.

Experts are also asking that people avoid activities that can contribute to air pollution during the day.. Such as mowing lawns and driving vehicles.

Hot, humid weather can create risks for people with certain heart conditions, including those on medications such as beta blockers and diuretics.
