You will be using Eco-Badge paper strips to monitor ground level ozone. The Eco-Badge will change color in the presence of ground level ozone. The card is used to interpret the color change. The Eco-Badge was developed by Mr. Gary Short of Vistanomics. Visit the Vistanomics website to learn more about the Eco-Badge, and air pollution.
You might also have this devise that will hold one of the Eco-Badge paper strips. Wear it around for a day and monitor the ozone in the places that you go!
