Embryotoxicity and fetal toxicity of nickel chloride (NiCl/sub 2/) and nickel subsulfide (Ni/sub 3/S/sub 2/) were studied in Fischer rats. Injection of NiCl/sub 2/ (16 mg of Ni/kg, im) on Day 8 of gestation reduced the man number of live pups per dam and resulted in diminisehd body weights of fetuses on Day 20 of gestation and of weanlings at 4 to 8 weeks after birth. Injection of Ni/sub 2/S/sub 2/ (80 mg of Ni/kg, im) on Day 6 of gestation reduced the mean number of live pups per dam. No congenital anomalies were found in fetuses from any Ni-treated dams, including dams that recieved 10 im injections of NiCl/sub 2/ (2 mg of Ni/kg, twice daily, on Days 6 to 10 of gestation). /sup 63/NiCl/sub 2/ (12 mg of Ni/kg, im) was administered to a group of nonpregnant female rats and to groups of pregnant rats on Day 8 or 18 of gestation. After 24 hr, the relative concentrations of /sup 63/Ni in tissues were: kidney > serum > adrenal approx. = lung approx. = ovary > spleen approx. = heart approx. = liver > skeletal muscle. Pituitary /sup 63/Ni concentrations were much higher in pregnant rats than in non-pregnant females. /sup 63/Ni concentrations in products of conception (embryos and embryonic membranes) on Day 9 and in placentas on Day 19 were equivalent to /sup 63/Ni concentrations in adrenal, lung, and ovary tissues of the dams. Autoradiography of fetuses and placentas on Day 19 of gestation showed /sup 63/Ni localization in fetal urinary bladders and in the basal laminae and yolk sacs of the placentas. These studies show (a) that im injection of NiCl/sub 2/ and Ni/sub 3/S/sub 2/ during early gestation causes embryonic mortality at dosages that do not cause maternal mortality, and (b) that /sup 63/Ni(II) can cross the feto-maternal barriers and enter the fetuses during late gestation.
