In the first half of the year, air quality in the urban areas of Quanzhou, a city in East China's Fujian province, was rated at an average of 97.3 percent at excellent quality, a year-on-year increase of 0.6 percent, according to the Quanzhou bureau of ecology and environment.

The key indicators for the six major pollutants -- SO2, NO2, PM10, PM2.5, O3, CO -- were better than the secondary standards of ambient air quality during the period.
