Electron paramagnetic resonance (EPR) was used in conjunction with energy dispersive x-ray spectroscopy (EDX) to quantify total copper and mobilized copper retentions in MCQ and MCA treated red pine. The MCQ treated red pine was found to have higher copper retention than that of the MCA treated one. Earlywood in general had higher total copper content than latewood. The mobilized and complexed copper retentions were similar in earlywood and latewood reflecting a similar capacity of each to solubilise and complex the mobile copper.
