China saw average concentrations of lung-damaging airborne particles known as PM2.5 fall by 10.8% from January to July as industry slowed because of the coronavirus, data showed on Friday, though levels were still well above WHO recommendations.
Average PM2.5 stood at 33 micrograms per cubic metre over the seven months, according to data collected from monitoring stations in more than 300 cities, the Ministry of Ecology and Environment said.
China’s national standard is 35 micrograms, though the World Health Organization (WHO) recommends levels of no more than 10.
PM2.5 is caused by the burning of fossil fuels and other industrial processes and is associated with a range of health problems, including respiratory disease and cancer.
