大气颗粒物源解析监测中的质量控制

为确保石家庄市大气颗粒物源解析研究数据的准确性和精密性,首先结合城市自然环境、能源结构、大气环境质量现状等进行合理布点采样,同时在大气颗粒物样品采集、滤膜称量、化学组分分析等监测过程中实施了空白分析、实验室平行样分析、标准曲线绘制与核查、加标回收、有证标准物质核查等一系列质量保证措施,通过对这些质量保证措施实施情况的阐述与质量控制数据的统计、计算与分析,证明了该大气颗粒物源解析监测工作从样品采集及其称量到化学组分分析等全过程是真实有效的,表明了石家庄市大气颗粒物源解析监测数据的准确性和监测工作的可靠性.

Quality control in the source apportionment of atmospheric particulate matter

To ensure the accuracy and precision of the source apportionment study data of atmospheric particulate matter in Shijiazhuang City,reasonable stationing sampling was implemented considering natural environment,energy structure and environmental quality,while in the atmospheric particulate matter sampling,filter weighing and chemical group monitoring process,the sub-analysis,gap analysis,laboratory parallel sample analysis,the standard curve drawing and verification,spiked recovery,verification of certified reference materials and a series of quality assurance measures were implemented.Through the implementation of these quality assurance measures and statistical calculation and analysis of quality control data,it proves that this source apportionment of atmospheric particulate matter is effective in monitoring sample collection,sample weighing and chemical composition analysis.It also indicates the accuracy of monitoring data and the reliability of the monitoring work of the source parse of atmospheric particulate matter in Shijiazhuang City.
