摘要:

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[α]芘测定的准确度控制指标，并与EPA 8270 D进行了比较，旨在为环境监测工作提供质量控制依据和指标。研究表明，标准样品测定的相对误差控制范围0～56.4%，实际样品加标回收率为55.8%～115%.

The Control Index of Accuracy for the Determination of Benzo(a)pyrene in Soil

Abstract:

On the basis of a large number of monitoring data from various laboratories in China, the accuracy control index for the determination of Benzo(a)pyrene in soil was studied. The index was compared with that in EPA8270D, so as to provide the QC reference and QC index for the environmental monitoring. The results indicated that the relative error control limits of standard samples were 0～56.4%, and the recoveries of real samples were 55.8%～115%.
