颗粒物手工监测与自动监测比对分析
|
摘要
基于泰州市环境空气颗粒物手工与自动监测比对工作,对2016—2018年比对监测数据进行相关性和偏差分析评价。结果表明:比对期间,PM_(2.5)手工与自动监测浓度的相对偏差为-35.2%～6.7%,平均相对偏差为-9.3%;PM_(10)手工与自动监测浓度的相对偏差为-30.3%～22.0%,平均相对偏差为-2.9%。结合PM_(2.5)、PM_(10)负偏差数据统计分析,颗粒物粒径越小,其手工与自动监测浓度相差越大。颗粒物手工与自动监测值在一定范围内有较好的线性关系,PM_(2.5)和PM_(10)这2项指标手工与自动监测浓度相关系数均达到0.95以上,相关性较好。
Based on the manual and automatic monitoring of ambient air particles in taizhou city, the correlation and deviation of 2016-2018 monitoring data was analyzed and evaluated.The results showed that the relative deviation of PM_(2.5) between manual and automatic monitoring concentration was-35.2% to 6.7%, and the average relative deviation was-9.3%.The relative deviation of PM_(10) between manual and automatic monitoring concentration was-30.3% to 22.0%, and the average relative deviation was-2.9%.Combined with the statistical analysis of PM_(2.5) and PM_(10) negative deviation data, the smaller the particle size, the greater the difference between the manual and automatic monitoring concentration.There is a good linear relationship between manual and automatic monitoring values of particles in a certain range.The correlation of PM_(2.5) and PM_(10) which monitored by manual and automatic is good and the correlation cofficients can reached more than 0.95.
