Air quality in Chinese cities improved in April amid the country's constant efforts to reduce pollution and promote green development, data from the Ministry of Ecology and Environment showed.
This was reported by The Xinhua News Agency.
For the 339 cities monitored by the ministry, the proportion of days with good air quality stood at 89.8 percent last month, up 8.7 percentage points year-on-year, according to the ministry.
The average density of PM 2.5, a key indicator of air pollution, remained unchanged from the same period last year at 28 micrograms per cubic meter, and that of PM 10 fell 3.6 percent year-on-year, said the ministry.
