Most Americans still live in unclean air
A new report finds that while air quality is improving in many U.S. cities, 175 million people–more than half the population–are still living in areas where the air is often too dangerous to breathe.
The study from the American Lung Association looked at the two biggest air pollution threats in the U.S.: ozone and particle pollution.
The report, based on 2006-2008 figures, credited cleaner diesel engines and controls on coal-fired power plants for decreasing pollution such as soot and dust. However, the report estimates that nearly 30 million people live in areas with chronic levels of pollution, so that even when levels are relatively low, people can be exposed to particles that will increase the risk of asthma, lung damage and premature death.
About 24 million people live in 18 counties with unhealthy levels of ozone, short-term particle pollution and year-round particle pollution, the report said, adding that new research shows the risk of health problems from pollution may be worse than once thought, especially for infants and children.
For the first time, the association included people living in poverty as one of its at-risk groups, reasoning that people with lower income levels face higher pollution risks.
