大量资料证明,有些食用海鱼和甲壳类含砷量高。人经口摄入无机砷后,大多数砷经尿排泄,剩余的储存在体内。为了评价砷在体内的储存程度,需要进行代谢平衡研究。作者用4只体重在2.9～4.4kg的成年雌猴作实验,实验期间随意供水供食,食物含砷0.10ppm,水含砷0.01ppm。在整个实验期间每日衡量食物消耗。接受剂量后每周记录体
A large number of data prove that some edible marine fish and crustaceans contain high levels of arsenic. After oral intake of inorganic arsenic, the majority of arsenic excreted by urine, the remaining stored in the body. In order to assess the extent of arsenic storage in the body, metabolic balance studies are required. The authors used four adult female monkeys weighing 2.9-4.4 kg to experiment. During the experiment, they were fed with water freely. The food contained arsenic 0.10ppm and water contained arsenic 0.01ppm. Daily measurement of food consumption throughout the experiment.
