佳木斯市特殊天气下非甲烷总烃与PM2.5相关性研究OA
Study on the Correlation between Non-methane Total Hydrocarbons and PM2.5 in Special Weather in Jiamusi City
大气污染发生等特殊天气条件下,环境空气中的非甲烷总烃与细颗粒物PM2.5之间有一定的相关性.分析佳木斯市轻度及以上污染天气下非甲烷总烃与PM2.5浓度变化规律及其相关性,结果表明:在不同的天气条件下,二者之间相关性有一定差异,在重污染天气下,皮尔逊相关系数、斯皮尔曼相关系数均最大,分别为0.763 6和0.740 0,二者具有较强正相关关系,而其他天气条件下一般为中等偏强正相关.同时,进一步验证了非甲烷总烃作为前体物对PM2.5生成的贡献.据此提出建议与措施,为打好大气污染防治攻坚战提供借鉴.
Under special weather conditions such as air pollution,there is a certain correlation between total non-methane hydrocarbons in ambient air and fine particulate matter PM2.5.Taking Jiamusi City as an example,the variation patterns and correlation between non-methane total hydrocarbons and PM2.5 concentrations under mild and above polluted weather conditions were analyzed.It was concluded that they have different correlations under different weather conditions.In heavily polluted weather,Pearson correlation coefficient and Spearman correlation coefficient were the largest,which are 0.7636 and 0.7400 respectively,indicating that they had a strong positive correlation.While in other weather conditions,the total non-methane hydrocarbons was generally moderately strong positive correlation.Meanwhile,the significant contribution of non-methane total hydrocarbons as precursors to PM2.5 formationfurther was verified.Based on this,suggestions and measures were proposed to provide reference for winning the battle against air pollution.
