Field tests were used to evaluate the durability of fenceposts treated with 6.5 kg of chromated copper arsenate (CCA) per m3 of wood. Decay was assessed by qualitative visual analysis and by changes in the chemical structure of the wood. Leaching of CCA from treated fencepost was evaluated by atomic absorption spectroscopy. Moreover, extractives and the acid insoluble lignin were quantified. Treated wood was in perfect condition after 6 yr, in contrast to the untreated wood. Percentages of extractives and lignin increased in the untreated decayed wood. Cr and Cu both migrated from wood to soil, but the concentrations were below those allowed by local environmental law. |
