我们研究了孕鼠接触砷对子代生长发育的影响，结果显示，染砷各组仔鼠机体砷和脑组织砷含量增高，大脑皮层神经细胞结构异常。０．７５ｍｇ／ｋｇ剂量组仔鼠表现为神经行为发育迟缓，外周血淋巴细胞α－醋酸萘酯酶（ＡＮＡＥ）阳性率降低．４．５０ｍｇ／ｋｇ剂量组仔鼠断乳后体重增长缓慢，血液胆碱酯酶活性降低，血清溶血素水平亦显著下降。表明砷可经母体影响胚胎和子代的生长发育。
We studied the effects of exposure to arsenic on the growth and development of offspring in pregnant rats. The results showed that arsenic and brain arsenic contents in arsenic-exposed groups were increased and the structure of neurons in the cerebral cortex was abnormal. In the 0.75 mg / kg dose group, the neurobehavioral development was delayed, and the positive rate of α -acetyl Naphthyl Acetate (ANAE) in peripheral blood lymphocytes decreased. 4.50mg / kg dose group weaned rats weight gain slowly after weaning, blood cholinesterase activity decreased, serum hemolysin levels also decreased significantly. Indicating that arsenic can affect the growth and development of embryos and offspring through the mother.
