USA - California Construction - Pollution... California's booming construction industry is belching air pollution that is increasing the risk of respiratory illness in the state's largest urban areas, an environmental group said in a report released on December 5, 2006. More then 1,100 people in California die prematurely each year from construction pollution, the scientists' report found. Bulldozers, backhoes and other kinds of construction equipment comprise the state's second-largest source of diesel-generated particulate pollution, a toxic soup of soot, ash and other compounds that embed themselves deep in lung tissues, the report said.
