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.*
This study aims to assess interrelationships between serum lead (Pb), cadmium (Cd), arsenic (As), and mercury (Hg) concentrations in pregnant women in their third trimester and umbilical cord blood, while inter-metal correlations were also determined. This study is part of the PIPA project (Childhood and Environmental Pollutant Project), whose pilot study was carried out from October 2017 to August 2018 and will be presented here. Blood samples were obtained from 117 mother-umbilical cord pairs and analyzed concerning metal concentrations.

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.
