Decline of maternal blood lead concentrations in Glasgow.
Seventeen years ago we reported the public health success of reduced lead exposure of mothers in Glasgow, achieved between 1977 and 1980 by increasing the pH of the water supply from 6.3 to 9.0 with lime to reduce plumbosolvency.A further reduction in plumbosolvency has now been made by addition of orthophosphate to the water supply. We report here on striking changes in maternal blood lead con...
متن کاملBlood Lead Changes during Pregnancy and Postpartum with Calcium Supplementation
Pregnancy and lactation are times of physiologic stress during which bone turnover is accelerated. Previous studies have demonstrated that there is increased mobilization of lead from the maternal skeleton at this time and that calcium supplementation may have a protective effect. Ten immigrants to Australia were provided with either calcium carbonate or a complex calcium supplement (approximat...
متن کاملDeterminants of bone and blood lead concentrations in the early postpartum period.
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 bone lead to blood lead. METHODS Maternal venous lead was measured at delivery and postpartum, and bone lead concentrations, measured with in vivo K-x ray fluorescence, were measured post partum. Data on environmental ex...
متن کاملLevels of lead in breast milk and their relation to maternal blood and bone lead levels at one month postpartum.
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 women with no current environmental or occupational exposures. Mobilization of maternal bone lead stores has been suggested as a potential endogenous source of lead in breast milk. We measured lead in breast milk to quan...
متن کاملPredicting blood lead concentrations from lead in environmental media.
Policy statements providing health and environmental criteria for blood lead (PbB) often give recommendations on an acceptable distribution of PbB concentrations. Such statements may recommend distributions of PbB concentrations including an upper range (e.g., maximum and/or 90th percentile values) and central tendency (e.g., mean and/or 50th percentile) of the PbB distribution. Two major, and ...
