About 80 percent of China's 367 cities with real-time air quality monitoring failed to reach national standards on small particle pollution in the first three quarters of the year, a report from Green Peace said on Thursday.
Central China's Henan province had the highest daily concentration of health endangering PM2.5 — particulate matter with a diameter smaller than 2.5 microns — during the period, the report said. Beijing ranked second.
The report released by Green Peace, a nonprofit environmental organization, said it relied on date from the China National Environment Monitoring Center, which updates air quality data hourly on PM2.5 and PM10 concentrations in the 367 cities.
Seven cities from Hebei province filled spots in a list of 10 with severe air pollution during September, the national environment watchdog said.
The Ministry of Environmental Protection released its monthly report on the air quality of 74 major cities on Wednesday, among which seven in Hebei including Hengshui, Tangshan and Shijiazhuang, were listed as having heavy air pollution.
Jinan in Shandong province ranked as the worst with Zhengzhou from Henan province second worst, the report said.
Although residents of the seven cities in Hebei witnessed heavy smog last month, the air quality in the Beijing-Tianjin-Hebei region has seen an improvement.
In the trilateral zone, the concentration of PM2.5 – particulate matter with a diameter smaller than 2.5 microns – has been lowered by 26.2 percent year-on-year, said Luo Yi, head of environment supervision of the ministry.
