They tested urine, blood, umbilical cord blood at childbirth, and milk on the third day after childbirth at 12, 32, and 40 weeks of gestation, respectively, and analyzed chromium compounds in aborted placenta and fetal tissue at 12 weeks of gestation. The results showed that the first group of pregnant women in various stages of blood, urine, cord blood and fetal
