According to a report “State Of The Air 2010” by the American Lung Association, seven California metropolitan areas where industry, farming, car culture and topography collide to strap smog make it onto the list of Top 10 Dirtiest Cities in America. Inhabitants in such areas face highly potential risk of asthma and chronic bronchitis. The following will draw smoggy pictures of cities again.

Previously, asthmatics flocked to Phoenix for clean air. Since the early 1990s, inhabitants of the Phoenix metropolitan area or the Valley of the Sun have been looking for some relief of their own. However, in 2005 the “Brown Cloud” which consists of tiny particles of carbon and nitrogen dioxide gas made the Valley of the Sun lose grade for air quality in ozone and particulates. The substances are mostly from burning fossil fuels. More than 2.6 million of the county’s residents are at high risk of respiratory complications.
