| Abstract: | The environmental monitoring data of air pollutants in Qianjiang District were evaluated by air quality comprehensive pollution index and Daniel trend test method to study the quality status and variation trend of air quality in 2012.Results showed that air quality comprehensive pollution index is 1.67,and the percentage of the days attaining the national air quality standards of Grade II is 94.2%.Inhalable particles are the primary air pollu-tant in QianJiang District.The development trends of ambient air quality indicated that the concentration of nitrogen dioxide and inhalable particles were increased during the year 2006 to 2012;Research of the monthly change indi-cated that ambient air quality in spring and summer was significantly better than in autumn and winter. |
