本研究是继环己基二甲胺基甲基三嗪二酮(Hexazinone)的急性毒性和环境毒性研究,为进一步评价该农药的安全性而进行的系列研究。大鼠90天喂饲和一代繁殖试验:雌、雄各64只,各分为四组,分别给予Hexazinone含量为0、200、1000和5000 ppm的饲料达90天,结果表明,5000 ppm剂量组的生长曲线略低于对照组;血象、生化和尿液分析均未发现与Hexazinone有关的改变;器官病理学 This study is a series of studies on the acute toxicity and environmental toxicity of Hexazinone to further evaluate the safety of this pesticide. Sixty-four male and female rats, each divided into four groups, were given diets containing Hexazinone at 0, 200, 1000 and 5000 ppm for 90 days, respectively. The results showed that the 5000 ppm dose group Growth curve was slightly lower than that of the control group; Hexazinone-related changes were not found in the blood, biochemical and urinalysis;
