土壤中苯并a芘测定的精密度控制指标研究

摘要

The monitoring data by the national labs,the precision control index for the determination of Benzo[a]pyrene in soil was studied,and compared with the index in EPA8270D,so as to provide the QC reference and QC index to the environmental monitoring.The results indicate that the within-laboratory relative standard deviation control limit of standard samples was less than 28%,the relative deviation was less than 34%.%通过全国多家实验室的大量监测数据,研究分析了土壤中苯并[a]芘测定的精密度控制指标,并与EPA8270D进行了比较,旨在为环境监测工作提供质量控制依据和质量控制指标。研究表明,标准样品的室内相对标准偏差的质量控制范围≤28%,室内相对偏差的质量控制范围≤34%。
