河南省五城市环境空气PM_(10)手工标准方法与自动监测法比对分析

在焦作、安阳、开封、三门峡、信阳5个城市开展PM_(10)手工标准方法和自动监测法比对实验,并用相关性和相对偏差对比对结果进行分析和评价。结果表明:12015年5个城市采集的PM_(10)手工和自动监测值均具有良好的相关性。22015年5个城市采集的PM_(10)手工和自动监测值的相对偏差为-19.1%~9.68%;负偏差数据占总数据量的75%。3PM_(10)手工和自动监测值|RD|平均值在中浓度下最小,高浓度下最大,低浓度介于二者之间,说明在高浓度和低浓度时PM_(10)的监测数据质量尤其值得关注。

The Comparison Analysis on Manual Standard Method and Automatic Method for Monitoring PM10 of Ambient Air in Five Cities of Henan Province

In this paper,we conducted a series of contrast experiment on standard manual method and automatic method for monitoring the PM10 of ambient air in Jiaozuo,Anyang,Xinyang,Sanmenxia and Kaifeng respectively,analyzed and evaluated the correlation and relative deviation of the comparison results.The results showed that: ①In 2015,the manual and automatic monitoring data of PM10 collected in 5 cities mentioned above all have good correlation.②The relative deviation of PM10 manual and automatic value collected in 5 cities is-19.1%~9.68%,and the negative deviation data account for 75% of the total data.③The average of the relative deviation of PM10 manual and automatic value is minimum at medium concentration, maximum at high concentration,the relative deviation at low concentration is between medium concentration and high concentration.It is showed that the quality of PM10 between high ambient air PM10 concentration and low ambient air PM10 concentration is particularly worthy of attention.
