毒理性
在这些两年喂养研究的条件下,C.I.颜料红23在雄性F344大鼠中具有不确定的致癌活性证据,表现为肾小管细胞肿瘤的发生率略有增加。在雌性F344大鼠中,没有证据显示C.I.颜料红23在含有10,000、25,000或50,000 ppm的饮食中具有致癌活性。单核细胞白血病在给予C.I.颜料红23的雄性和雌性大鼠中的发生率降低。在雄性和雌性B6C3F1小鼠中,没有证据显示C.I.颜料红23在含有10,000、25,000或50,000 ppm的饮食中具有致癌活性。
... Conclusions: Under the conditions of these 2 yr feed studies, there was equivocal evidence of carcinogenic activity of C.I. Pigment Red 23 in male F344 rats as evidenced by a marginally increased incidence of renal tubule cell neoplasms. There was no evidence of carcinogenic activity of C.I. Pigment Red 23 in female F344 rats fed diets containing 10,000, 25,000, or 50,000 ppm. Mononuclear cell leukemia occurred with a decreased incidence in male and female rats receiving C.I. Pigment Red 23. There was no evidence of carcinogenic activity of C.I. Pigment Red 23 in male and female B6C3F1 mice fed diets containing 10,000, 25,000 or 50,000 ppm.
