A new study released by the World Health Organization on Thursday called air pollution a human carcinogen like tobacco smoke, asbestos and arsenic, calling it a leading cause of cancer deaths globally.
Health experts have known for years that air pollution increases the risk of a wide range of ailments, including respiratory problems and heart disease.
Some compounds in the air we breathe, such as diesel exhaust, have already been deemed cancer-causing.
The World Health Organization says air pollution caused more than 220,000 lung cancer deaths worldwide in 2010.
