防腐処理木材が生体に及ぼす影響

Effect of contact to wood treated with chromated copper arsenate (CCA) wood preservative and alkyl ammonium compound (AAC) wood preservative on living body was observed by raising mice on the treated wood chips for a month. Extraction of the treated wood and ash of the treated wood by water was made, and the solution was given to mice as drinking water for a week.
No significant effect was observed in the contact test to the treated wood chips by mice. No difference was detected between physiological characteristics of mice which drank the extractive of the treated wood and those of mice which drank the control extractive. There was no difference also in the case of the extractive of the ash.
