Abstract
The objective of this work was to evaluate the performance of 10 amazonian wood species of low natural durability, to treatment with CCA preservative (2% concentration): it was concluded that all species studied are easily treated with this preservative. The sapwood showed high absorption and total penetration. The heartwood is relatively easy to preserve, exception to Parkia nitidae (Fava), Qualea paraensis (Mandioqueiras), Erisma unicatum (Quarubarana), and Virola sp (Ucuúba), which presented some restrictions. Nevertheless, it does not mean that their treatment is impossible.
