COLUMBUS, Ohio — The Air Quality Alert issued for several central Ohio counties has been extended through Thursday. The alert is in effect due to wildfire smoke from Canada being funneled through much of the East Coast and Midwest.

The pollution levels in Franklin, Fairfield, Delaware and Licking counties are expected to be unhealthy for sensitive groups. The last time central Ohio experienced unhealthy pollution levels for sensitive groups was in August 2010, according to the Mid-Ohio Regional Planning Commission.

A cold front will move across central Ohio, shifting winds to the north and northwest. The winds will carry dense smoke from eastern Canadian wildfires into the region, further increasing particle pollution levels.

With the mix of partly sunny skies and temperatures being in the low-80s, the air quality will be unhealthy for some groups.

Moderate northerly winds will persist on Thursday. While these winds will aid dispersion, they will also continue to carry smoke into central Ohio. These conditions will result in high-moderate AQI levels.

What is the Air Quality Index?

The AQI scale is the Environmental Protection Agency's index for reporting air quality and runs from 0 to 500. The higher the AQI value, the greater the health concern.

When AQI levels reach above 100, air quality is considered unhealthy for sensitive groups. The MORPC then issues an Air Quality Alert.

Tuesday's rating on the Air Quality Index (AQI scale is 103 and the areas affected by the alert — Franklin, Delaware, Fairfield and Licking counties — are likely to experience particle pollution levels that are unhealthy for sensitive groups.

Who is impacted?

Active children, the elderly, and people with asthma and COPD are more likely to suffer an increase in the number and severity of symptoms during an Air Quality Alert.

To decrease the potential for health issues, sensitive groups are urged to limit their outdoor activity or plan outdoor activities for the morning. Those who are experiencing breathing difficulties should consult their doctor.

What actions should you take?

On Air Quality Alert days, MORPC recommends taking action to improve air quality. The majority of particle pollution levels come from vehicle emissions and burning activity.
