Mortality from ambient air pollution

Situation and trends

In the year 2012, ambient air pollution was responsible for 3.7 million deaths, representing 6.7% of the total deaths. Worldwide, ambient air pollution is estimated to cause about 16% of the lung cancer deaths, 11% of chronic obstructive pulmonary disease (COPD) deaths, more than 20% of ischaemic heart disease and stroke, and about 13% 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.
