Despite the recent declines in environmental lead exposure in the United States and
Mexico, the potential for delayed toxicity from bone lead stores remains a significant public …

OBJECTIVE This study investigated determinants of bone and blood lead concentrations in
430 lactating Mexican women during the early postpartum period and the contribution of …

Despite the many well-recognized benefits of breast-feeding for both mothers and infants,
detectable levels of lead in breast milk have been documented in population studies of …

To evaluate the hypothesis that lactation stimulates lead release from bone to blood, the
authors analyzed breastfeeding patterns and bone lead concentrations as determinants of …

This study examined the determinants of blood lead (BPb) in 513 pregnant women in
Mexico City: 311 from public hospital prenatal clinics, representing primarily women of low …

Recent research has raised the possibility that fetal lead exposure is not estimated
adequately by measuring lead content in maternal whole blood lead because of the variable …

We examined bone lead contribution to blood lead in a group of 311 immigrant women, 99%
from Latin America, during the third trimester of pregnancy and 1 to 2 months after delivery …

The authors studied 367 women who were breastfeeding their infants in Mexico City,
Mexico, between 1994 and 1995 to evaluate the effect of cumulative lead exposure …

Blood lead levels declined among Americans aged 1–74 y between the years 1976 and
1991 (National Health and Examination Survey [NHANES III]). In 1990, umbilical cord blood …

We measured high precision lead isotope ratios and lead concentrations in blood, urine,
