Ozone
Three sources of pollutant Motor vehicle exhaust and industrial emissions Power plants Chemical solvents
Indoor or outdoor pollutant Normal substance in the atmosphere but a pollutant at ground level. Prevalent in air as other polluntants react with sunlight Indoor pollution from ozone is less than 50% of that found in ambient air
Primary or secondary polluntant It is a secondary polluntant. Forms when other pollutants react with sunlight.
Human health effects Short term exposure can effect the lungs, the eyes, and even increase susceptibility to allergens Long term exposure can reduce lung function.
Environmental effects Ozone affects sensitive vegetation and ecosystems, including forests, parks, wildlife refuges and wilderness areas. In particular, ozone harms sensitive vegetation during the growing season.
Prevention/reduction techniques EPA’s national and regional rules to reduce emissions of pollutants that form ground level ozone will help state and local governments meet the Agency’s national air quality standards.
