Early life is a vulnerable window for metal exposure, with potential adverse health effects that may last throughout the life course. This study aims to explore the association between metal mixture exposures and the neurodevelopment of children in Spain.  \nMETHOD:The study population (n = 962) belonged to the INMA Project. A standardised version of the McCarthy Scales of Children's Ability was used to assess 4-year-old children's neurodevelopment. The concentrations of As species, Co, Cu, Mo, Pb, Se and Zn were measured in spot urine samples adjusted for urine dilution. Principal component analysis was performed as a dimension reduction technique to identify latent metal mixtures. The association between the metal mixtures and children's  \nneurodevelopment function scores was explored using multiple linear regression adjusted for confounding factors.  \nRESULTS:Four principal components or metal mixtures were identified with a cumulative explained variance of 69% . The first component comprised the essential elements Cu, Se, and Zn, as well as the toxic metal Pb, and was linked to a decreased performance in global verbal, executive, verbal executive, and working memory function scores.
