TL;DR: Environmental lead exposure in children who have maximal blood lead levels < 7.5 μg/dL is associated with intellectual deficits, and an inverse relationship between blood lead concentration and IQ score is found.
Fetal Lead Exposure at Each Stage of Pregnancy as a Predictor of Infant Mental Development

TL;DR: Fetal lead exposure has an adverse effect on neurodevelopment, with an effect that may be most pronounced during the first trimester and best captured by measuring lead in either maternal plasma or whole blood.
Reduced intellectual development in children with prenatal lead exposure.

TL;DR: Lead exposure around 28 weeks gestation is a critical period for later child intellectual development, with lasting and possibly permanent effects, and most lead-associated child IQ decreases measured over the studied BPb range.

Birgit Claus Henn,Adrienne S. Ettinger,Adrienne S. Ettinger,Joel Schwartz,Martha María Téllez-Rojo,Héctor Lamadrid-Figueroa,Mauricio Hernández-Ávila,Lourdes Schnaas,Chitra Amarasiriwardena,David C. Bellinger,Howard Hu,Robert O. Wright,Robert O. Wright +12 more
TL;DR: An inverted U-shaped association between 12-month blood manganese and concurrent mental development scores is observed, suggesting a possible biphasic dose-response relationship between early-lifeManganese exposure at lower exposure levels and infant neurodevelopment.

Associations of early childhood manganese and lead coexposure with neurodevelopment.

TL;DR: Evidence of synergism between lead andManganese was observed, whereby lead toxicity was increased among children with high manganese coexposure and the importance of understanding health effects of mixed exposures, particularly during potentially sensitive developmental stages such as early childhood is highlighted.
