Article Synopsis
- The PIPA Project is a birth cohort study in Rio de Janeiro that investigated toxic metal concentrations in maternal and umbilical cord blood of infants to understand their impact on neurodevelopment.* -
- The study found that all tested samples contained detectable levels of arsenic, cadmium, lead, and mercury, with higher lead levels noted in premature newborns and significant arsenic levels in the infants who showed developmental delays.* -
- Results showed a concerning correlation between higher maternal blood arsenic levels and neurodevelopmental issues in infants, highlighting the need for more research on the effects of prenatal metal exposure.*
Background: Environmental metal exposure during pregnancy can affect intrauterine growth and disrupt child development. Metal exposure in urban areas can occur through the air, water and food routes. The city of Rio de Janeiro is the second more populous of Brazil and the sixth most populous in the American continent and is characterized by a significant social-economic inequality and a large range of urban organization problems.
