| Abstract: | The monitoring data by the national labs,the precision control index for the determination of Benzoa]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%. |
