Resumo(s)
Subtoxic blood lead levels (BLL) during pregnancy can be responsible for intrauterine
delays in foetal development and thus increased risk of morbi-mortality of newborns. Since there is no protective transplacental barrier to lead, foetal exposure is due to maternal
environmental exposure together with either increased absorption or bone demineralization with consequent release of lead, or both, that may occur during
pregnancy. In non-occupationally exposed women, lead exposure may be increased due to
residing near lead sources, consumption of polluted food products, and habits such as
alcohol consumption and tobacco smoking. The main purpose of this study was to provide
Portuguese data on the extent and pattern of foetal exposure to lead as determined through
lead biomonitoring in the blood of pregnant women. Investigation on maternal BLL
determinants and potential effects of subtoxic BLL on premature delivery and on
newborn's characteristics was also objective of this study.
