Development and certification of a sediment reference material for selected polynuclear aromatic hydrocarbons Burlington, Ont. : Analytical Methods Division, National Water Research Institute, Canada Centre for Inland Waters, 1985. 16, [6] p. : ill. NWRI contribution ; 85-119 Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographical references. "The Quality Assurance and Methods Section has developed and certified a new certified reference material (CRM) for polynuclear aromatic hydrocarbons (PAH). Such compounds are important toxic contaminants and are also classified as US EPA priority pollutants. Previous interlaboratoriy data showed wide disparity in PAH results, indicating that there was a need to improve on and monitor the quality of these data. The development of this CRM for quality assurance applications will be invaluable in all future analytical measurment of PAH"--Management perspective.
