In this paper, results of relevant pollutants (Cl, As, Cd, Cr, Cu, Pb) of waste wood assortments are presented. The samples were as-signed to the categories without wood preservatives A I (natural), A II (painted, coated) and A III (treated with halogenated organic compounds) according to the guidelines and examples of the Waste Wood Ordinance (AltholzV, 2002). The pollutant contents of 58 samples were determined by X-ray fluorescence and mass spectrometric analysis methods (XRF and ICP-MS). The surfaces of the samples and homogenised samples were analysed by XRF and compared with the results of digested sub-samples (ICP-MS). The results demon-
strate that in the above mentioned categories for the recycling of waste wood 36 % of the samples show higher pollutant levels than allowed. Therefore the division of waste wood according to the Waste Wood Ordinance and optical criteria is inadequately to exclude a diffuse input of pollutants in wood materials. A similar statement is obtained when comparing the levels of pollutants with the more restrictive
maximum allowable values for wood chips for non-industrial use (DIN 14961-4, 2011).
