The World Health Organization (WHO) on Thursday classified outdoor air pollution as a leading cause of cancer in humans.
“The air we breathe has become polluted with a mixture of cancer-causing substances,” said Kurt Straif of the WHO’s International Agency for Research on Cancer (IARC).
“We now know that outdoor air pollution is not only a major risk to health in general, but also a leading environmental cause of cancer deaths.”
The IARC said a panel of top experts had found “sufficient evidence” that exposure to outdoor air pollution caused lung cancer and raised the risk of bladder cancer.
Although the composition of air pollution and levels of exposure can vary dramatically between locations, the agency said its conclusions applied to all regions of the globe.
Air pollution was already known to increase the risk of respiratory and heart diseases.The Raw Story
