A proposed reference study for the determination of dibenzofuran and dibenzo-p-dioxin in defoamers / by National Water Research Institute, Research and Applications Branch. "An interlaboratory study in which eight laboratories participated was conducted for the determination of non-chlorinated dibenzo-p-dioxin (DBD) and dibenzofuran (DBF) in defoamers. Participants were requested to analyze DBD and DBF in two standard solutions and five fortified defoamers using a proposed reference method. The objectives of this study were to characterize the performance of the proposed method in terms of accuracy, interlaboratory (overall) precision, intralaboratory (within-lab) precision for the determination of DBD and DBF in defoamers as well as to assess the performance of participating laboratories"--Abstract, page iii.
