Breathing polluted air - is like smoking

Your lungs may be at risk, even if you never smoking: Enough to live in a city with polluted air. according to ExplorationPublished in the "Journal of the American Medical Association," to live in a city with high levels of ozone for 10 years - it's like that smoke a pack of cigarettes a day for 30 years.

This is the first study that examines in great detail the long-term effects of air pollution lung health in adults. Scientists have examined more than seven million adults in six major areas, including highly contaminated New York and Los Angeles. With the emergence of emphysema have been associated with different types of pollution - the presence in the air of solid particles, black carbon, and nitrogen oxide atmospheric ozone. With the latter everything it is especially bad.

Ozone is formed when sunlight interacts with chemicals that emit cars and other sources of pollution. Things get worse when increasing the ambient temperature - and now this problem is particularly acute.

To somehow solve the problem, the researchers propose to move to electric vehicles, and more often to walk and ride

bicycles. The more fossil fuels we use, the worse the air quality and the more the climate is changing.
