ABTM为一种新型木材防腐剂,动物急性毒理实验表明,大、小鼠经口LD_(50)分别为1.8±0.06g/kg、2.17±0.089/kg,大、小鼠经皮LD_(50)>5.0g/kg,蓄积系数>3。大、小鼠、家兔经3个月至6个月喂饲、卧防腐据末染毒实验,经体重增长、血象、肝肾组织检测,与对照组动物无显著差异。该防腐剂用Ames菌株检验为阴性反应,小鼠骨髓微核实验呈致突变阳性反应。 ABTM is a new type of wood preservative. Animal acute toxicological tests showed that the LD 50 of large and small mice were 1.8 ± 0.06g / kg and 2.17 ± 0.089 / kg, respectively. )> 5.0g / kg, accumulation coefficient> 3. Rats, rabbits and rabbits were fed for 3 months to 6 months. According to the experiment of decoction and decay, the rabbits and rabbits were not significantly different from the control group by weight gain, blood, liver and kidney. The preservative was tested negative by the Ames strain and showed a mutation-positive response in the mouse bone marrow micronucleus test.
