当前，没有多少风险比空气污染对全球卫生的影响更大；
“Few risks have a greater impact on global health today than air pollution; the evidence signals the need for concerted action to clean up the air we all breathe.”
After analysing the risk factors and taking into account revisions in methodology, WHO estimatesindoor air pollution was linked to 4.3 million deaths in 2012 in households cooking over coal, wood and biomass stoves.
The new estimate is explained by better information about pollution exposures among the estimated 2.9 billion people living in homes using wood, coal or dung as their primary cooking fuel, as well as evidence about air pollution's role in the development of cardiovascular and respiratory diseases, and cancers.
