Abstract (2. Language): 
In this study, the effect of blue-staining on the leachability of CCA elements from CCA-C treated and stained red pine specimens was evaluated. The specimens were first blue-stained in laboratory conditions using Cera-tocystis pilifera, C. huntii, C. coerulescens, and Aurobasidium pullulans fungi and then treated with 1% CCA-C solution. After fixation period, the specimens were subjected to 336-h of leaching according to modified AWPA standard method. The blue-staining fungi used in this study had no effect on major wood components, however subsequent degradation of ray parenchyma, tracheid walls and pits by blue-staining fungi used in this study caused increasing of permeability of wood. On the basis of all leached elements, C. pilifera and C. huntii caused somewhat more leaching of CCA from the specimens compared to percentage leaching rate of CCA in control specimens.

Abstract (Original Language): 
Bu çalışmada mavi renk oluşumunun emprenye edilmiş ağaç malzemeden Cu, Cr ve As elementlerinin yıkanması üzerine etkisi incelenmiştir. Dört farklı mavi renk mantarı ile mavileşmiş örnekler %l konsantrasyonda CCA-C çözeltisi ile emprenye edildikten sonra 14 gün süren yıkama işlemlerine tabi tutulmuştur. Araştırma sonucunda mavi renk oluşumun yıkanan element yüzdeleri üzerine önemli bir etkisi olmadığı belirlenmiştir.
