摘要
目的评价2001—2010年南京地区大气质量现状及其变化趋势,为进一步研究大气污染对人群健康的影响提供依据。方法选择SO2、NO2、PM103个代表性指标作为评价因子,利用Daniel趋势检验的秩相关系数法对监测结果进行评价分析。结果 10年间南京地区SO2年均浓度保持平稳状态(P>0.05),NO2年均浓度呈上升趋势(P<0.05),PM10年均浓度呈下降趋势(P<0.05)。结论南京市大气中NO2污染较为严重,提示加强机动车尾气排放治理迫在眉睫。
Objective To evaluate the present situation of the air quality and change tendency of typical regional of Nanjing from 2001 to 2010,and to explore the relationship between disease spectrum and air pollution. Methods Three representative targets of Sulfur dioxide（SO2 ）,Nitrogen dioxide（NO2） and inhalable particle matter（PM10 ） were chosen as appraisal factors, change tendency of ambient air quality of Typical Regional were studied and analyzed by adopting Spearman rank correlation coefficient method of Danniel tendency examination. Results From 2001 to 2010, SO2 annual average concentration was maintained steady state（P〉0.05）. The overall trend of annual average concentration of NO2 was increased （P〈0.05）. The general trend of PM10 annual average concentration was decreased（P〈0.05）. Conclusion The pollution of NO2 was more severe in Naniing. So, There is an urgent task to strengthen the motor vehicle emissions control.
