摘　　要：针对《固定污染源废气低浓度颗粒物的测定重量法(HJ 836—2017)》的检出限、精密度、正确度和全程序空白的测试分析表明:监测数据准确,可靠,检出限、精密度、正确度和全程序空白均能满足标准方法的要求。通过对标准方法中检出限、精密度、正确度和全程序空白的测试分析以准确掌握固定源颗粒物的浓度及其排放量的问题,同时掌握区域的整体环境质量以及环境污染情况,对日常的颗粒物超低排放监测与总体情况掌控具有良好的促进作用。The test analysis of the detection limit,precision,accuracy,and full program blank of the"Determination of Low Concentration Particle Matter in Fixed Pollution Source Waste Gas by Gravimetric Method(HJ 836—2017)"shows that the monitoring data is accurate and reliable,and the detection limit,precision,accuracy,and full program blank can all meet the requirements of the standard method.By testing and analyzing the detection limit,precision,accuracy,and full program blank in standard methods,the concentration and emission of fixed source particulate matter,as well as the overall environmental quality and pollution situation of the region are accurrately grasped.This has a good promoting effect on daily monitoring of ultra-low particulate matter emissions and overall situation control.
