Experts and residents in the worsthit areas such as Shijiazhuang are becoming increasingly worried about the air pollution brought by frequent winter haze. “Small particles in the air can cause heart disease,stroke,respiratory illness,birth defects and cancer,” said Zhou Rong,director of the Greenpeace climate and energy project.Shijiazhuang has been enveloped by haze and fog since Sunday,according to the local weather bureau. “I have rarely seen haze persist for so long.The air smells like burnt coal,and I have to cover my nose,” said Li Ning, a worker in his 30s. “I really want to know if the haze has any impact on my health,” he added.Yang Ping,a doctor at Hebei Provincial People's Hospital,said there has been an increase in child and elderly patients since the haze started to affect Shijiazhuang on Sunday.
A report by Greenpeace and Peking University's School of Public Health said an estimated 8,572 premature deaths occurred in Shanghai,Guangzhou,Xi'an and Beijing in 2017 because of high levels of PM 2.5 pollution.The report called for regional coal consumption to be capped.
PM 2.5 refers to particles less than 2.5 micrometers in diameter,which can enter the lungs and bloodstream.Haze often means increased PM 2.5 density.
Chen Wanqing,deputy director of the National Central Cancer Registry,under the Ministry of Health,said that lung cancer rate is rising sharply in China and tends to affect young people,but did not explain why.
