中文摘要:
      为研究焦作市大气污染特征及其相关性,对2015—2017年焦作市4个国控空气监测点位的监测数据进行统计分析。结果表明:2015—2017年城区环境空气污染 SO2、NO2、CO、PM10、PM2.5浓度均呈逐年下降趋势;大气污染浓度季节变化特征明显,PM10、PM2.5、SO2、NO2、CO的浓度均为冬季最高、夏季最低,空气质量指数也在冬季达到最高值;O3浓度则为夏季最高、冬季最低。2017年焦作市沙尘天气共计36 d,严重影响了环境空气中颗粒物的浓度。由PM2.5与PM10的比值说明大气颗粒物污染以PM2.5为主。通过SPSS软件分析,SO2、NO2、CO、PM10、PM2.5浓度间呈两两正相关,O3浓度与NO2、CO呈负相关。
英文摘要:
      To study the pollution characteristics and relevance of atmospheric pollutants in Jiaozuo, this paper analyzed the 2015-2017 monitoring data of 4 ambient air monitoring sites in Jiaozuo. The results showed that the concentrations of SO2, NO2, CO, PM10, PM2.5decreased in the city year by year.Atmospheric pollutants had obvious seasonal characteristics. The concentration of PM10, PM2.5, SO2, NO2, CO were the highest in winter and lowest in autumn, while the AQI was the highest in winter. But the concentration of O3 was the highest in summer and lowest in winter. The dusty weather in 2017 totaled 36 d, which seriously affected the concentration of particulate matter in the ambient air.The ratio of atmospheric PM2.5 to PM10 showed that atmospheric particulate matter pollution is mainly caused by fine particulate matter. Analysis by SPSS software, there was a positive correlation between the SO2, NO2, CO, PM2.5and PM10 concentrations. Negative correlations existed between the O3 concentration and the NO2, CO concentrations.
