"An interlaboratory round-robin study for PAH analysis in sediment and solution samples was organized. Results from 15 Canadian laboratories were received and evaluated. The interlaboratory results on a standard solution of PAH revealed a surprisingly large degree of disparity with a median relative standard deviation (RSD) of 40%. RSDs for PAH results in the two sediment extracts and two sediment samples of relatively high PAH levels (ca. 1 to 20 Hg/g) were very similar. For most of the results the interlaboratory RSD was close to 100%. Various extraction and cleanup methods were used by the participants and identification and quantification of PAH were done by either the HPLC, GC-FID or GS-MS techniques"--Abstract.
