According to a recent study more than 500,000 Americans die each year from cardiopulmonary disease breathing polluted air.
They die prematurely more than 3800 people each year in Los Angeles and San Joaquin Valley of Southern California because air pollution levels violate federal standards. The six more common air pollutants are Ozone, Particulate Matter, Carbon Monoxide, Nitrogen Oxides, Sulfur Dioxide, Lead. The worst ever incident of air pollution in the United States of America occurred in Donora, Pennsylvania in 1948, when 20 people died and over 7,000 were injured.
The report from 2009 has stated that six out of ten Americans live in urban areas where air pollution can cause major health problem. The National Ambient Air Quality Standards (NAAQS) applies for outdoor air throughout the country. They are designed to not only protect human health but also the public welfare.
