Colorado health officials give warning of Front Range contamination


DENVER – Health officials are warning this weekend of potentially unhealthy air pollution along Colorado's Front Range due to high levels of ozone.

The Colorado Department of Health and Human Services issued an ozone warning that would remain in effect until at least 4 p.m. Sunday.

The agency says that active children and adults and people with lung conditions such as asthma should reduce prolonged or strenuous exercise in the outdoors.

The affected area includes southern and western parts of the Denver area, north to Boulder and Fort Collins.

Ozone at ozone level is created when vehicle exhaust gases, paints, cleaning agents and other chemicals react with sunlight. It usually gets worse in the summer and can cause serious respiratory problems and asthma attacks.
