[New York Times]  Outdoor air pollution contributes to the deaths of an estimated 1.6 million people in China every year, or about 4,400 people a day, according to a newly released scientific paper…

According to the data presented in the paper, about three-eighths of the Chinese population breathe air that would be rated “unhealthy” by United States standards…

They analyzed four months’ worth of hourly readings taken at 1,500 ground stations in mainland China, Taiwan and other places in the region, including South Korea. The group said it was publishing the raw data so other researchers could use it to perform their own studies…

The Berkeley Earth paper’s findings present data saying that air pollution contributes to 17 percent of all deaths in the nation each year. The group says its mortality estimates are based on a World Health Organization framework for projecting death rates from five diseases known to be associated with exposure to various levels of fine-particulate pollution. The authors calculate that the annual toll is 95 percent likely to fall between 700,000 and 2.2 million deaths, and their estimate of 1.6 million a year is the midpoint of that range…

Much of China’s air pollution comes from the large-scale burning of coal. Using pollution measurements and wind patterns, the researchers concluded that much of the smog afflicting Beijing came not from sources in the city, but rather from coal-burning factories 200 miles southwest…
