The Oak Ridge National Laboratory has evaluated a multilaboratory Soxtec PCB extraction study and has compiled the date from the eight participating laboratories. The experiment required each laboratory to extract PCB aroclor 1254 and 1260 from 10-g samples of Fuller s earth on 3 nonconsecutive days. Each sample was to be spiked at a concentration level of 5 ppm or 50 ppm. The average for all PCB percent recovery values is 88%, with a 95% confidence interval of (82%,93%). The estimated standard deviation for a single measurement within a laboratory is 19%. 2 refs., 2 tabs., 1 fig.
