| Abstract: | The sand-block method was adopted for testing the toxicity of 15 water-borne and 3 oil solvent preservatives against wood decaying fungi. The results of the toxicity of 18 formulated preservatives against Coriolus verszcolor, Poria placenta and Coniophora puteana are summarized as follows:* 1. the toxicity of preservatives CCA_3, CCA_4, CCA_5, CCB_1, CCB_3, CCB_5, BBF, FBP, whose threshold retentionis 3.4-5.0 kg/m~3, is higher than that of any other water borne ones.* 2. the toxicity of preservative P-B with a 0.7-1.8 kg/m~3 is the highest in 3 oil solvent preservatives.* 3. the leaching toxicity of CCA appears much higher than that of CCB, BBF, and FBA. |
