The haze that has enveloped China’s capital Beijing for several days straight is largely triggered by the emission of sulfur dioxide from burning coal in the neighboring Hebei Province, said a pundit from the Chinese Academy of Sciences (CAS). 

Having analyzed the data of real-time monitoring, Wang Yuesi, a researcher of the Institute of Atmospheric Physics of CAS, explained that only a minor proportion of the sulfur dioxide diffusing in the air in downtown Beijing, which is the catalyst for the impenetrable haze, is discharged by the city itself.  

Most of the toxic chemical substance, however, is produced by the burning of coal in Hebei Province and even Tianjin, which are located in close vicinity to the capital, Wang said. 

Official statistics show that 23 million tons of standard coal are burned in Beijing per year. That figure soars to 70 million and 270 million when it comes to Tianjin and Hebei respectively.
