Manganese concentrations in drinking water from villages near banana plantations with aerial mancozeb spraying in Costa Rica: Results from the Infants' Environmental Health Study (ISA)
(Elsevier, 2016-03)Elevated manganese (Mn) in drinking water has been reported worldwide. While, naturally occurring Mn in groundwater is generally the major source, anthropogenic contamination by Mn-containing fungicides such as mancozeb ... -
Manganese in teeth and neurodevelopment in young Mexican-American children
(Elsevier, 2015-10)Introduction: Manganese (Mn) is an essential nutrient but higher exposure has been associated with poorer neurodevelopment in children. Methods: We measured Mn levels in prenatal (Mnpre) (n=197) and postnatal (Mnpost) ... -
Maternal blood and hair manganese concentrations, fetal growth, and length of gestation in the ISA cohort in Costa Rica
(Environmental Research, 2015-01)Background: Animal studies have shown that both deficiency and excess manganese (Mn) may result in decreased fetal size and weight, but human studies have reported inconsistent results. Methods: We examined the association ... -
