The International Agency for Research on Cancer (IARC), the specialized cancer agency of the World Health Organization (WHO), data revealed on 17 October 2013 that exposure to outdoor air pollution causes lung cancer and increases the risk for bladder cancer.
The IARC data highlighted that air pollution is already known to increase risks for a wide range of diseases, such as respiratory and heart diseases. It also noted that air pollution exposure levels increased significantly in some parts of the world, particularly in rapidly industrialising countries with large populations.
The data revealed that 223000 deaths from lung cancer in 2010 were caused by air pollution.
According to the data the predominant sources of outdoor air pollution are transportation, stationary power generation, industrial, agricultural emissions and residential heating and cooking. Some air pollutants have natural sources as well.
