Summary This paper provides an update covering the change in availability of NBS Biological Reference Materials between the First and the Second Symposium on Biological Reference Materials. In the intervening 30-month period, 15 new reference materials of biological interest have been issued by NBS and 8 more are being prepared. Newly issued reference materials that are described include: corn kernel, corn stalk, lead in blood, trace elements in human serum, inorganic constituents in bovine serum, PCB's in human serum, blood gases, toxic elements in urine, dioxin in isooctane, ethanolwater solutions, chlorinated pesticides and chlorinated biphenyls in isooctane. Several new Standard Reference Materials have been introduced to aid analysts in testing instrument performance. These are intended to provide a baseline of instrument performance, independent of the matrix analyzed. Described are 36 solution standards for spectrometric methods, a wavelength standard for spectrophotometers, a temperature standard, and one for evaluating GC/MS system performance.
