摘要
从2011年12月1日开始在常规空气监测点对影响吉林市空气质量的两个颗粒物指标PM2.5和PM10进行了同步比对监测。结果表明:PM2.5和PM10有显著的相关性,相关系数为0.982;采暖期PM2.5和PM10的比值平均为0.57。分别采用现行和新标准对监测结果进行了评价,其结果好于二级天数将比现行标准评价结果减少12.4%。
PM2z and PM10, the primary pollutants affecting on environmental air quality in Jilin City, were monitored comparatively at routine monitoring sites from December 1,2011. The results showed that: PM2.5 and PM10 had significant correlation, and the correlation coefficient was 0.982; during the heating period, the average ratio between PM25 and PM10 was 0.57. The monitoring data was evaluated by existing and new standard respectively.
