The state Department of Environmental Quality is warning people who are sensitive to air pollutants to be careful Monday.

The DEQ has declared the first ever Ozone Action Day for the metro area because ozone levels are expected to reach 104 on the federal air quality index Monday afternoon.

This is the first time the DEQ has declared such a day, but the warning is only targeted at certain groups of people.         

Te Ozone level is expected to reach 104 - 101 is considered unhealthy for sensitive groups.

The DEQ says those sensitive to air pollutants such as children, the elderly and people with lung disease like asthma, emphysema or chronic bronchitis should avoid prolonged outdoor activities.

The unhealthy air quality could cause shortness of breath and difficulty breathing.

Several areas are impacted by the alert, including Orleans, Jefferson, Plaquemines, St. Bernard, St. Charles, St. John the Baptist and St. Tammany Parishes.

Experts say the high levels are caused by emissions from vehicles, gas stations, power plants, paints and cleaners.

The DEQ is asking people to cut back on emissions by conserving energy at home, carpooling, refueling after 6 p.m. and making sure your gas cap is on tight.

The DEQ adds that levels in Baton Rouge Monday will reach 122.
