Air Pollution Is Deadlier Than We Thought
Air pollution exposure was responsible for about one in eight deaths in 2012 and is now the greatest environmental health risk known to humanity, according to a new World Health Organization (WHO) report. Although the problem is global, death from air pollution is most prevalent in Southeast Asia and the Western Pacific, where air pollution deaths totaled 5.6 million in 2012. Surprisingly, indoor air pollution claims more lives than outdoor air pollution in these regions.
\"Poor women and children pay a heavy price from indoor air pollution since they spend more time at home breathing in smoke and soot from leaky coal and wood cook stoves,\" explains Flavia Bustreo, WHO’s Assistant Director of General Family, Women, and Children’s Health.
The report links both indoor and outdoor air pollution to significantly higher rates of stroke and heart disease, as well as higher rates of respiratory disease and lung cancer.
And the risks don’t end there—new data presented at the Society of Toxicology’s annual meeting suggests a link between air pollution exposure and obesity rates in developed countries.
While the connection has not yet been confirmed, \"the experimental evidence that does exist provides a potential causal relationship between air pollution and a number of metabolic processes, including glucose intolerance, insulin resistance, and body fat inflammation,\" explains Urmila Kodavanti, an EPA researcher who co-presented the findings at the conference. —Keturah Hetrick
