Association of prenatal maternal blood lead levels with birth outcomes in the Japan Environment and Children ’s Study (JECS): a nationwide birth cohort study

ConclusionsEven at a maternal BLL below 1.0  µg/dL, prenatal lead exposure was associated with decreased birthweight and increased risk of SGA and LBW, but not preterm delivery. The adverse effect estimates of prenatal lead exposure on birth outcomes were quantitatively small and clinically limited at this low level.
