镉对哺乳动物生殖力及后代发育的影响,从本世纪初开始,各国学者进行了大量的实验研究。已初步证实,镉对哺乳动物生殖力及后代发育有损害作用。但有关在环境接触条件下镉对哺乳动物生殖力和后代发育的影响如何,尚未有明确结论。为此,我们进行了以下实验研究。 选用昆明种小鼠,雌70只、雄35只,体重12～ Cadmium on mammalian fecundity and the development of future generations, from the beginning of this century, scholars from various countries conducted a large number of experimental studies. It has been initially confirmed that cadmium has a detrimental effect on the mammalian reproductive capacity and the development of the offspring. However, no clear conclusion is drawn on the effect of cadmium on mammalian reproductive capacity and the development of offspring under environmental exposure conditions. To this end, we conducted the following experimental study. Selected Kunming mice, 70 females, male 35, weight 12 ~
