Cuyahoga County is once again under an Air Quality Advisory, this time through Tuesday night.

As of 6 p.m. Monday, the Air Quality Index (AQI) registered at 143. Anything over 100 is considered “Unhealthy for Sensitive Groups.”

The Northeast Ohio Areawide Coordinating Agency (NOACA) issued the alert. It lists ozone as the main pollutant in counties along Lake Erie, from Lorain to Ashtabula and south, including Medina, Summit and Portage counties.

We expect to see some relief Wednesday. The forecast is for the AQI to drop to moderate throughout our area.

Air quality advisories are issued when levels will impact “children, the elderly and those with breathing difficulties,” according to the agency’s website.

In addition to monitoring outdoor activity, NOACA suggests the following:

Drive less: Bike, walk, use public transit, work from home or combine trips. Visit GOhioCommute.com/NOACA to find smarter ways to travel.

When driving, don’t idle: Turn off your engine.

Refill your tank after sunset.

Wait a day to mow during growing season.

Pollution can cause health difficulties including chest pain, coughing, throat irritation and congestion in some people. Those with bronchitis, emphysema and asthma may find their symptoms worsening.
