The efficient recycling of waste wood, which accumulates in large quantities in numerous sectors, is becoming increasingly important in terms of sustainable resource management. Since wood was often impregnated with substances that are now banned in the past, the use of waste wood (recycling or incineration) is regulated in several European countries. Reliable analytical data are thus required for a decision regarding the further use of waste wood, which - due to their great economic and ecological impact - must be backed up by suitable quality control.
The two new certified reference materials BAM-U030 and BAM-U130 replace the first material ERM-CD100, which has been sold out in the meantime and in which the mass fractions of arsenic, cadmium, chromium, copper, lead, mercury and pentachlorophenol (PCP) were certified. The starting materials were different types of wood, which were crushed by cryogenic grinding and then prepared to obtain contents of heavy metals (BAM-U130) or PCP (BAM-U030) in the range of the limit values of the Waste Wood Ordinance.
The two CRMs can be used within the framework of internal laboratory quality assurance to verify (determine the trueness and precision) the analytical results obtained with known test methods and to validate modified or new methods.
