    Analysis on the Pollution Status and Change Trend of PM2.5 in the Atmosphere in Nanjing

      摘要
    • 摘要:
      目的 分析2007-2011年江苏省南京市某区大气中PM2.5的污染现状, 评价其变化趋势, 为进一步研究PM2.5对人群健康的影响提供依据。
      方法 以南京市某区2007-2011年间的大气补充监测数据为依据, 选择PM2.5指标作为评价因子, 运用Spearman秩相关系数预测其发展趋势。
      结果 该区PM2.5月均浓度变化接近于U型, 季节性变化较为明显, 5年间年均浓度变化呈下降趋势(P < 0.05)。
      结论 该区PM2.5污染的控制和治理取得一定成效, 但整体污染浓度仍较高, 需进一步调整工业布局, 加快地方性法规、规章和规范性文件的制定步伐。

       

      Abstract:
      Objectives To analyze the concentrations of PM2.5 of one district in Nanjing city from 2007 to 2011, evaluate the change tendency, and to explore the relationship between the effect on health and PM2.5 concentration.
      Methods Based on the major supplementary monitoring data of one district in Nanjing city, PM2.5 as a representative target indicator was chosen as an appraisal factor, its change tendency was studied by adopting Spearman rank correlation coefficient method of Danniel tendency examination.
      Results The change tendency of monthly average concentrations PM2.5 was closed to the U type, showing the difference of seasonal variations. The main pollutant was PM10. From 2007 to 2011, the overall trend of annual average concentrations of PM2.5 was decreased (P < 0.05).
      Conclusions The control and administration of PM2.5 are efficient but the pollution with PM2.5 was still severe in that district. The industrial layout should be further adjusted and local regulations, rules and normative documents should be formulated.
