摘要
以PM 10,SO 2和NO 2为空气质量评价对象,采用综合污染指数法研究了山阴县空气环境质量及其变化趋势.结果表明,山阴县主要空气污染物PM 10,SO 2和NO 2浓度的年内变化均大致呈先降低后升高的趋势,采暖期空气综合污染指数明显高于非采暖期.2005—2015年山阴县空气综合污染指数明显下降,空气环境质量由中度污染转为轻度污染,整体空气环境质量有了显著改善.
This paper took PM 10,NO 2 and SO 2 as the targets and discussed the ambient air quality and trends in Shanyin County of Shanxi Province based on the comprehensive pollution index method.Results showed that annual variations of the main pollutants——PM 10,NO 2 and SO 2 all decreased at first,and then increased.The values of the comprehensive pollution indexes in the heating period were greater than those in the non-heating period.The values of the comprehensive pollution indexes during the past 10 years reduced sharply,the ambient air quality has been transformed from moderate-to mild-pollution status.The overall air quality has improved significantly.
