I’m a runner. I wasn’t always a runner. But, after my first race this spring, I had to admit it. Running may have been an easy sport to pick up when the first marathon was run in Greece, but today there are many more considerations.

First, what shoes do I get? Are they light and supportive? Will they match my clothes? Sorry, I had to throw it in there.

Then you have to decide where to run. I love that I live so close to the city, but that also means I’m surrounded by busy roads and traffic. On my first run at my new house, I decided to just explore the neighborhood. After a mile, I noticed that it wasn’t as easy as it used to be.

Was I out of shape? Maybe it was just a bad day. After a couple more bad runs, it dawned on me. Maybe it was running next to a busy road.

Running near busy roads exposes you to higher levels of air pollutants. And breathing dirty air makes it harder to do just about everything. So, I made a few changes. I looked for routes that were in or near a park or on back roads. I even woke up earlier so I could beat the traffic.

But it’s not just busy roads that can affect air quality. Air pollution comes from many other sources. And it changes every day, so just like I check the weather, I started checking the Air Quality Index. For me, poor air quality days don’t mean skip the run, they just mean take it easy, slow the pace or cut the distance.

EPA uses a color-coded guide: green means the air quality is good, red means it’s unhealthy for everyone to breathe. You can check it on the Internet, sign up for daily emails, or check out your local weather report.

Cities across the country also have Air Quality Action Days. These days tell you when you should reduce your contribution to pollution. One of he easiest ways to do that is to leave the car at home. You can take public transportation or carpool.

Poor air quality can happen year-round, so no matter when you’re outside, check the AQI.

April 27 – May 1 is Air Quality Awareness Week.

About the author: Kelly Leovic has been with EPA since 1987, doing indoor air research and then exposure research before beginning her dream job of educational outreach in 2003.

I loaded the lung capacity kit, Watts meter, and brochures into my car and couldn’t believe that I was getting paid to do this! Today was my 3rd year staffing our EPA Booth at the Durham Bulls Education Day - same team as Bull Durham movie, just a new ballpark.

At 9:30 a.m., over 3,000 students, 1st grade through high school, and their chaperones and teachers descended upon the Ballpark. Instantly, our table was surrounded by students anxious to measure how many cups of air they had in their lungs or to compare the wattage of a CFL with a traditional bulb.

Lung capacity is always the most popular activity at our booth, so the next 3 hours went something like this:

A class of 3rd graders surrounds our table curious about the big bucket of water with a tube.

Kelly: Today we are going to do an experiment to measure how many cups of air you have in your lungs.

Kid #1: Is it free?

Kelly: Sure is! Now take a clean straw, and put it into the end of the tube attached to the bucket. Take a deep breath and blow all the air out of your lungs into the tube. Then we’ll measure how many cups of water you emptied. Only take one breath. (We can’t use the term “water displacement” with 3rd graders!)

Kid #1 begins to blow, and we all cheer words of lung-emptying encouragement. I play judge, making sure no one sneaks in an extra breath.

Kelly: Nice job. Now, let’s measure how many cups of air you had. Wow…8 cups! (Most kids measure between 4 and 16 cups of air.)

Finally, we then talk about why some kids might have more capacity than others and how exercise can improve lung capacity.

I repeat this, smiling and saying “nice job,” approximately 172 times that day. In the spirit of exercise and health, my favorite part is talking to the students about their sports. I especially enjoy when they play basketball or tennis, run track, or swim because those are sports that my kids do. I also love their “competitive” spirit in trying to outdo their classmates.

Education Day was a great way to celebrate National Air Quality Awareness Week and Asthma Awareness Month. Oh, and did I mention that, to top it off, the Durham Bulls won, 2-0?!
