A good friend of mine recently returned from her mother’s funeral in Germany. She had died of lung cancer after spending the last eight years of her life in a slum in New Delhi where she taught orphaned children.
I can’t help but wonder if breathing the dirty indoor and outdoor pollution in New Delhi contributed to her cancer. My friend has the same question.
In new estimates released March 25, the World Health Organization (WHO) reports that in 2012, about 7 million people died - one in eight of total global deaths – as a result of air pollution. Indoor air pollution was linked to 4.3 million deaths in households that cook over coal, wood and biomass stoves. Outdoor air pollution was linked to 3.7 million deaths from urban and rural sources worldwide. (As many people are exposed to both indoor and outdoor air pollution, mortality attributed to the two sources cannot simply be added together.)
South and East Asia had the largest number of deaths linked to indoor air pollution.
The WHO finding more than doubles previous estimates and confirms that air pollution is now the world’s single largest environmental health risk. In particular, the new data reveal a stronger link between both indoor and outdoor air pollution exposure and cardiovascular diseases, such as strokes and ischemic heart disease, as well as between air pollution and cancer. In the case of both indoor and outdoor air pollution related deaths, 6 percent were attributed to cancer.
Thinking that my friend’s mother perished as result of pollution may not be so far-fetched.
