@airtrackapp: What exactly is O3 (Ozone) and why should you care? Next up in our air quality series with our Chief Scientific Officer, Will Hicks talks about Ground-Level Ozone (O3). ☀️🚗 Unlike the good ozone layer high in the stratosphere, ground-level O3 is a harmful air pollutant created when traffic fumes react with heat and sunlight. While you can’t see it, inhaling high levels can irritate your lungs, trigger coughing, and worsen conditions like asthma—especially on sunny days. Have you ever checked air quality before heading out for a walk, run, or commute? Let us know below! 👇 And if you’d like to stay on top of what you’re breathing, try AirTrack Premium for £1.99 upgrading this September!
