### The Soaking Method  
The results for the soaking method are presented in Table 1. The soaking method did not produce a statistically significant difference between the values in almost all wood species soaked for 15, 60, and 480 min and in each biocide. The exception is stone pine sapwood, which showed as a rule a higher uptake compared to the other species. It can be assumed that the higher uptake of stone pine sapwood, when the soaking method is used, is a consequence of its porous structure, as already supposed when water is used as \begin{table}
