Air pollution in India is reported to cause 527,700 deaths a year.
According to a new World Health Organisation (WHO) study, only China has more number of premature pollution-related deaths than India, while the United States comes a close third.
According to the World Health Organization (WHO) report, diseases triggered by indoor and outdoor air pollution kill 656,000 Chinese citizens each year, and polluted drinking water kills another 95,600.
"Air pollution is estimated to cause approximately two million premature deaths worldwide per year," National Geographic quoted Michal Krzyzanowski, an air quality adviser at the WHO Regional Office for Europe, as saying.
In the United States, premature deaths from toxic air pollutants are estimated at 41,200 annually.
Krzyzanowski worked with the WHO to develop new air quality guidelines that set out global goals to reduce deaths from pollution.
Damaging air pollutants include sulphur dioxide, particulate matter-a mixture of extremely small particles and water droplets-ozone, and nitrogen dioxide. China accounts for roughly one-third of the global total for these pollutants, according to Krzyzanowski. (See a map of China.)
The combustion of fossil fuels-whether to power China's many automobiles, its burgeoning factories, or its expanding megacities-is a primary source of outdoor air pollutants.
The burning of coal or charcoal to heat homes, common throughout China, also produces a range of indoor air pollutants. (Related: "China's Boom Is Bust for Global Environment, Study Warns" [May 16, 2005].)
