Health and Environmental Impacts of Air Pollution
Mobile sources of air pollution emit ozone, particle pollution, and air toxics. The health effects of mobile source air pollution affect millions of people, especially people who live near busy roads. The environmental impacts include haze in many parts of the U.S., including many of our national parks and wilderness areas, and the acidification of lakes and streams.
The impacts of climate change include warming temperatures, changes in precipitation, increases in the frequency or intensity of some extreme weather events, and rising sea levels. These impacts threaten our health by affecting the food we eat, the water we drink, the air we breathe, and the weather we experience.
