Beijing was one of the 10 Chinese cities with the worst air quality in July, according to a ranking released by the ministry of environmental protection (MEP) on Monday.
Nearly 65 percent of July days were polluted in the capital, with one day of heavy pollution, and the main pollutants were ozone and PM2.5, Xinhua cited the monthly report, which reviews air quality in 74 cities.
Air quality in the Beijing-Tianjin-Hebei region in July was worse than the month before, although it had improved year on year, the report said.
The MEP also named the 10 cities with the best air quality in July. They included Haikou, Lishui, Fuzhou, Jiangmen, Zhuhai, Zhoushan, Xiamen, Huizhou, Zhongshan and Shenzhen.
