Mortality and burden of disease from ambient air pollution
Situation and trends
In the year 2012, ambient air pollution was responsible for 3 million deaths, representing 5.4% of the total deaths. Worldwide, ambient air pollution is estimated to cause about 25% of the lung cancer deaths, 8% of chronic obstructive pulmonary disease (COPD) deaths, about 15% of ischaemic heart disease and stroke, and about 17% of respiratory infection deaths.
Particulate matter pollution is an environmental health problem that affects people worldwide, but low- and middle-income countries disproportionately experience this burden.
