"Polychlorinated biphenyl (PCB) is one of the most frequently analyzed organic environmental pollutants. However, interlaboratory results indicated that analytical measurements for PCBs are not reliable. In order for the laboratory managers and supervisors to assess quality of PCB data, they Quality Assurance and Methods Section has developed and certified a sediment certified reference material (CRM) for total PCB analysis. This material has already been successfully applied in several interlaboratory studies. It has also been used as in-house quality control samples or as check samples included in contracts by WQNL, WQB-OR, EPS-0R, DFO and other provincial and private laboratories"--Executive summary.
