2006～2012年武陵山区黔江区域大气污染物变化分析及防治对策

Variation Analysis and Control Countermeasures of Atmospheric Pollutants in Qianjiang District of Wuling Mountain Area from 2006 to 2012

利用黔江区环境空气的监测资料,采用空气综合污染指数、Daniel趋势检验方法等评价和分析方法,研究了2006～2012年环境空气质量状况及变化趋势.结果表明,SO2 、NO2和PM10年均浓度分别为0.019 ～0.060、0.004 ～0.022、0.063 ～0.089 mg/m3,均达到国家二级标准限制要求.环境空气综合污染指数为1.08 ～2.14,属于轻度污染,主要污染物为SO2和PM10.2006～2012年环境空气质量年际变化趋势表明,NO2浓度随年份变化呈增长趋势.根据黔江区环境空气质量状况,分析了污染成因,并提出了污染防治对策.

By using environmental monitoring data of air pollutants in Qianjiang District,adopting air quality comprehensive pollution index and Daniel trend test method,the quality status and variation trend of air quality from 2006 to 2012 was studied.The results showed that the annual average concentration values of SO2,NO2 and PM10 were 0.019-0.060,0.004-0.022,0.063-0.089 mg/m3,respectively,which have attained the national standards for grade Ⅱ.The imegrated pollution indexes of air environmental was 1.08-2.14,belong to light pollution,including SO2 and PM10.The variation trends of anbient air quality indicated that the concentration of NO2 increased during 2006-2012; According to the analysis on air quality in Qianjiang District,the pollution causes were analyzed,and control countermeasures were put forward.
