title: Maternal and fetal chromosomal aberrations in mice following prenatal exposure to subembryotoxic doses of lead nitrate.
abstract: Maternal exposure to low levels of lead nitrate (12.5, 25, 50 mg/kg body weight), administered on the 9th day of gestation, did not cause embryonic resorption and fetal lethality, but induced chromosomal deletions and other forms of aberrations in fetal liver and maternal bone marrow cells.
