Summer Heat and Bad Air

Wow, what a beautiful day!  Gorgeous blue sky and low humidity. What a keeper!  Tomorrow will be about the same.  This warmer air can come with a price…bad air.  The first Air Quality Alert of the season has been issued for tomorrow.  Changes are coming later in the week to mix it up, Dan Thomas had more on that  in his earlier blog, click here.


But back to the Air Quality Alert for tomorrow. An alert is issued when the amount of ground level ozone increases.  Tomorrow is a Code Orange Day which means the air quality will be dangerous for sensitive groups. Those sensitive groups include people with lung disease including Asthma, active adults and children are most affected by ground level ozone. If this is you or a loved one, consider limiting or rescheduling strenuous outdoor activities until the air quality improves. Pollution levels tend to be lower in the morning and evening.


There are actually some things we can all do to reduce air pollution.

LEAVE THE CAR PARKED – Share a ride to work, bike  or use public transportation. Bring your lunch, or walk to lunch instead of getting in your car.

DRIVE SMART – Combine errands, skip the drive thru, limit engine idling, and avoid rush hour.

PUT A HOLD ON SOME BACKYARD ACTIVITIES – Avoid using gas-powered yard equipment, and save the grilling out for another day.

Warm, dry air is conducive for pollutants to accumulate in the air. Air Quality Alerts are issued because of predicted high levels of ozone, fine particle pollution (PM2.5), or both.
The highest ozone levels usually occur from 2 p.m. to 7 p.m. in Middle Tennessee, so reschedule or cut back on outdoor activities, particularly during these times. But,
unhealthy levels of PM2.5 can occur at any time during the day. People with heart and lung disease, older adults and children are particularly at risk from exposure to fine particles.

Humidity levels will rise later in the week and the chance of rain will increase.  Both will help wash some of the pollutants out of the air.
