百菌清13周亚慢性吸入毒性实验表明,高浓度组(5.31mg/m~8)动物呈轻度粘膜刺激,血清谷丙转氨酶明显下降,嗜伊红细胞、血清总蛋白均明显升高,肝、肾、肺出现出血、炎性坏死病灶。低浓度组(1.16mg/m~3)除部分动物嗜伊红细胞增多外,未见其他异常。结果提示百菌清亚慢性吸入阈浓度为1.16mg/m~3。 Chlorpyrifos 13-week sub-chronic inhalation toxicity experiments showed that high concentration group (5.31mg / m ~ 8) animals showed mild mucosal irritation, serum alanine aminotransferase decreased significantly, eosinophils, serum total protein were significantly increased, liver , Kidney, lung bleeding, inflammatory necrosis lesions. Low concentration group (1.16mg / m ~ 3) except for some animals, eosinophilia, no other abnormalities. The results suggest that the chlorothalbuterol chronic inhalation threshold concentration of 1.16mg / m ~ 3.
