The toxicity of the herbicide Agroxone 3, a commercial formulation of the sodium salt of 2-methyl-4-chlorophenoxyacetic acid (MCPA), in the adult newt (Triturus cristatus carnifex) was tested after percutaneous exposure. At the concentration of 3200 ppm, the LT50 values were 17 and 21 hr for male and female newts. At 1600 ppm, the LT50 values were 35 and 45.5 hr. At 800 ppm, most of the animals were still alive after the 3 months of experimentation. There were no deaths at 400 and 200 ppm. Severe neuromuscular disorders were observed in animals exposed to lethal concentrations.
对除草剂“地乐酚3号”（2-甲基-4-氯苯氧基乙酸钠（MCPA）的一种商业制剂）在成年蠑螈（Triturus cristatus carnifex）经皮暴露后的毒性进行了测试。在3200 ppm的浓度下，雄性和雌性蠑螈的半数致死时间（LT50）值分别为17小时和21小时。在1600 ppm时，LT50值分别为35小时和45.5小时。在800 ppm时，经过3个月的实验，大多数动物仍然存活。在400 ppm和200 ppm时没有死亡情况。在暴露于致死浓度的动物中观察到了严重的神经肌肉紊乱。
