Of them, 17 cities, or 3.6 %, achieved the primary level standard. Some 373 cities,
or 79.2 %, reached the secondary level, while 73 cities, or 15.5 %, achieved the

the local level or higher is 85.0 %, of which 85.5 % are county-level cities. The
percentage of cities administered at the local level or higher, including provincial
capitals, that achieved the national primary level for air quality was 3.3. Cities that
reached the secondary level accounted for 78.4 % of the total, while those that met
the third level accounted for 16.5 %, and cities below the third level accounted for
1.8 %. The cities in which the annual density of inhalable particles met or fell below
the secondary-level standard accounted for 85.0 %, and those below the third level
accounted for 1.2 %. The cities in which the annual density of sulfur dioxide met or
fell below the secondary-level standard accounted for 94.9 %, with no cities below
the third level. The density of nitrogen dioxide in all the cities not under direct
control of the central government met the secondary-level standard, and 86.2 % of
the cities achieved the primary level [ 4 ].
