Triazoles are commonly used wood preservatives active against a wide range of fungi and bacteria. A full understanding of their diffusion and distribution in wood is essential for the development of enhanced treatment protocols ensuring long-term stability of wood products. Moreover, determining the fate of sorbed triazoles is critical to minimize their losses, but also to assess the environmental impact of the treated wood product. Herein, the diffusion, distribution and environmental fate of triazoles was studied using a radiolabeled tracer, 14C-uniformly-labeled tebuconazole. The wood-treatment technique was representative of industrial practices for the manufacturing of above-ground products such as windows and doors; specifically, ponderosa pine wood was dip-treated with a solvent-based, metal-free formulation. A three-step extraction protocol was developed for triazole isolation from wood along with sensitive analytical techniques for fungicide quantification including liquid scintillation counting and solid phase extraction followed by liquid chromatography - Time-of-flight mass spectrometry.
