污染 Pollution in China
Coal is the leading culprit of air pollution in China. A recent study of the University of Leeds sponsored by Greenpeace East Asia traced PM2.5 (fine particles with a diameter under 2.5µm) in the Beijing-Tianjin-Hebei region and found the amount of PM2.5 released into the air in 2010 alone was more than ten million tons.
The study also confirmed that the majority of air pollution happens when certain gases are discharged into the air and turn into fine particles. And coal burning contributes most of these gases.
China's epic climb to the world's second-largest economy has had devastating health impacts. Another research project co-authored by Greenpeace on the health impacts of coal power plants shows that PM2.5 pollution from the 196 coal-fired power plants in the capital region of Beijing-Tianjin-Hebei caused 9,900 premature deaths and nearly 70,000 outpatient visits or hospitalizations during 2011. 75% of the premature deaths are caused by the 152 coal-fired power plants in Hebei Province.
Air pollution will remain a serious problem in China as long as coal continues to be the country's major energy source.
PM2.5 concentration levels have particularly endangered public health in big cities like Beijing, Shanghai, Guangzhou and Xi’an. The PM2.5 concentration levels in all four cities exceed World Heath Organisation (WHO) air quality guidelines. This means higher health risks to the cardiovascular system, cerebrovascular system and an increase in the probability of cancer and premature death.
