- 9 out of 10 people in the world breathe air that is highly polluted, a new report says
- Air pollution is found in the home and outdoors
- About 7 million people die each year because of this pollution, the WHO says
The study is an analysis of what the WHO says is the world's most comprehensive database on ambient air pollution. The organization collected the data from more than 4,300 cities and 108 countries.
"I'm afraid what is dramatic is that air pollution levels still remain at dangerously high levels in many parts of the world," Dr. Maria Neira, director of the WHO's Department of Public Health, Environmental and Social Determinants of Health, said of the study published Tuesday. "No doubt that air pollution represents today not only the biggest environmental risk for health, but I will clearly say that this is a major, major challenge for public health at the moment and probably one of the biggest ones we are contemplating."
