Certification of the mass fractions of trace elements and pentachlorophenol in an impregnated wood reference material
- The resource-saving utilisation of recovered
waste wood is a matter of growing concern. In several
European countries, this utilisation is governed by regulations
and is dependent on the contents of certain trace
elements and organic compounds. Thus, for decisionmaking
with respect to waste wood management (recycling
or combustion), reliable analytical data are needed and, due
to their great economic and environmental impact, must be
assured by appropriate quality control. To support the
improvement in quality assurance in waste wood analysis,
for the first time, a wood reference material was certified
for its mass fractions of arsenic, cadmium, chromium,
copper, lead, mercury, and pentachlorophenol (PCP).
These analytes were selected because they represent typical
constituents of wood preservatives most widely used in the
past. Material preparation and testing of homogeneity and
stability were carried out by BAM Federal Institute for
Materials Research and Testing. The certificationThe resource-saving utilisation of recovered

were performed involving selected laboratories
with documented expertise in the field of waste wood
analysis. The certified values and their corresponding
uncertainties were assigned in full compliance with the
requirements of ISO Guide 35. The certified mass fractions
and their expanded uncertainties (k/i> = 2) are as follows:
(3.1 ± 0.5) mg/kg for As, (3.02 ± 0.24) mg/kg for Cd,
(36.4 ± 2.6) mg/kg for Cr, (22.9 ± 1.7) mg/kg for Cu,
(0.60 ± 0.14) mg/kg for Hg, (39 ± 4) mg/kg for Pb, and
(7.9 ± 0.6) mg/kg for PCP. The certified material is
available as European Reference Material ERM®-CD100.…
