Sunlight Nitrogen OxidesVolatile Organic
Compounds
Ozone
Pollutants “bake” together in direct sunlight, forming ozone
NOx VOCs O3

OZONE EFFECTS ON HEALTH
Children & seniors People with asthma, bronchitis or COPD Those who spend more time outdoors
Who is most at risk?
When & where are risks highest?
