What is the current health burden from air pollution?
We set out to answer this important question as part of the Global Burden of Disease project. The Global Burden of Disease project estimated that, in 2015, breathing fine particulate matter, in the air was responsible for about 4.2 million early deaths from heart disease and stroke, lung cancer, chronic lung diseases, and respiratory infections. In addition, breathing ozone in the air was estimated to contribute to 254,000 additional deaths due to its effect on chronic lung disease.
How important is the burden of disease from air pollution?
We know that many other risk factors (such as poor diet, high blood pressure, and tobacco smoking) also contribute to the same diseases as air pollution and can cause people to die prematurely. Understanding how air pollution ranks relative to these other risk factors helps identify priorities for actions that could most improve public health.
The Global Burden of Disease project found that exposure to fine particulate matter was the 5th leading contributor globally to early deaths. Fine particle levels alone accounted for about 7.6 % of all deaths.
