description A composite wood product and methods for manufacturing the same and determining the concentration and distribution of an organic biocide within a composite wood product are provided. The organic biocide may be added to wood elements (i.e., fibers, flakes, strands, veneers) prior to consolidation and/or heating of the wood particles to form the composite wood product. A tracer additive may be mixed with the biocide, or applied separately to the furnish which is used to produce the composite wood product. The tracer additive may be detected via, for example, x-ray fluorescence. An amount of tracer additive detected may correlate to an amount of organic biocide within the wood elements and/or the composite wood product. On présente un produit ligneux composite ainsi que des méthodes permettant de fabriquer celui- ci et de déterminer la concentration ainsi que la distribution d'un biocide organique dans le produit ligneux composite en question. Le biocide organique peut être ajouté à des éléments ligneux (c'est-à-dire des fibres, des flocons, des lamelles ou du placage) avant agglomération et/ou chauffage des particules de bois pour former le produit ligneux composite. Un additif de marquage peut être mélangé avec le biocide ou appliqué séparément à la composition de fabrication utilisée pour obtenir le produit ligneux composite. L'additif de marquage peut être détecté, par exemple, par fluorescence aux rayons X. Une corrélation peut être établie entre la quantité d'additif de marquage détectée et la quantité de biocide organique dans les éléments ligneux et/ou dans le produit ligneux composite.
