Air pollution is killing an average of 4,000 people a day in China, according to researchers who cited coal-burning as the likely principal cause.
Deaths related to the main pollutant, tiny particles known as PM2.5s that can trigger heart attacks, strokes, lung cancer and asthma, total 1.6 million a year, or 17 percent of China’s mortality level, according to the study by Berkeley Earth, an independent research group funded largely by educational grants. It was published Thursday in the online peer-reviewed journal PLOS One from the Public Library of Science.
“When I was last in Beijing, pollution was at the hazardous level: Every hour of exposure reduced my life expectancy by 20 minutes,” Richard Muller, scientific director of Berkeley Earth and a co-author of the paper, said in an e-mail. “It’s as if every man, woman and child smoked 1.5 cigarettes each hour.”
