Outdoor Air Pollution Kills 3 Million Globally, Wood Burning, Fertilizer Top Causes

摘要

Outdoor air pollution contributed to 3.3 million deaths worldwide in 2010, with wood-burning stoves in China and India and ammonia-belching farms in the West among the biggest culprits, according to a new study. And if nothing is done, the annual toll from dirty air could double to 6.6 million premature deaths by 2050, with the biggest rise coming in Asia, researchers said Sept. 16 in the journal Nature. The study used new atmospheric models and emissions data to offer a more comprehensive view of pollution sources and how the effects vary across the globe.
