2 Million Deaths Yearly Worldwide Linked with Air Pollution
By Rachael Rettner, Senior Writer, LiveScience
Date: 11 July 2013 Time: 07:00 PM ETAir pollution may be responsible for more than 2 million deaths around the world each year, according to a new study.
The study estimated that 2.1 million deaths each year are linked with fine particulate matter, tiny particles that can get deep into the lungs and cause health problems.
Exposure to particle pollution has been linked with early death from heart and lung diseases, including lung cancer, the researchers said; meanwhile, concentrations of particulate matter have been increasing due to human activities. The study also found that 470,000 deaths yearly are linked with human sources of ozone, which forms when pollutants from sources such as cars or factories come together and react. Exposure to ozone has been linked to death from respiratory diseases.
Most of the estimated global deaths likely occur in East and South Asia, which have large populations and severe air pollution, said study researcher Jason West, an assistant professor of environmental sciences at the University of North Carolina at Chapel Hill.
