摘要

通过对十八种药剂配方（其中水溶性配方15种、油溶性配方3种）对木腐菌的毒性试验及对初筛后的配方进行流失后毒性试验,结果表明,水溶性配方中的铜铬砷即CCA,3,、CCA,4,、CCA,5,铜铬硼即CCB,5,配方,以及油溶性配方中的P—B剂的毒性较大。

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.
