In Fontana, the main air pollutant is O3. It mostly comes from Ozone forms when sunlight reacts with gases from vehicles and industries. It can irritate the lungs and throat and make it difficult to breathe especially for people with asthma. To stay safe, Try to avoid outdoor exercise during afternoon hours when ozone levels are usually high.
