To determine the impregnative effects of the oscillating pressure method (OPM) for the pressure treatment of wood, a laboratory scaled OPM machine was prepared and impregnation tests of water-borne preservatives were carried out comparing with the conventional Bethell method. Four wood species, sugi (Cryptomeriajaponica), karamatsu (Larix leptolepsis), hemlock (Tsuga heterophylla), douglas fir (Pseudotsuga menziesii) and radiata pine (Pinus radiata), and two commercialpreservatives, CCA (JIS K 1554 Type 1) and DDAC (Penta-cure New BM^R, Xyence Co. Ltd.), were tested for this experiment.

Tannins and related phenolic compounds have chlating ability with metal ions and antimicrobial activity. We studied on inhibitory effect of phenolic compounds on chlorpyrifos degradation by metal ions and soil microorganisms.
As a result, phenolic compounds could mitigate one enable to reduce chlorpyrifos degradation by metal ions and soil microorganisms. Pyrogallol and gallic acid shows the most positive effects on inhibition of chlorpyrifos degradation among all phenolic compounds tested.
