Infants growing up in low- and middle-income countries are at increased risk of suffering adverse childhood experiences, including exposure to environmental pollution and lack of cognitive stimulation. In this study, we aimed to examine the levels of metals in the human milk of women living in São Paulo City, Brazil, and determine the effects on infants' neurodevelopment. For such, a total of 185 human milk samples were analyzed for arsenic (As), lead (Pb), mercury (Hg), and cadmium (Cd) using inductively coupled plasma mass spectrometry (ICP-MS).

The migration test was carried out by contacting plastic material with food simulant. Migration concentrations and average silver particle sizes were determined by mass spectrometry with inductively coupled plasma, performed in single particle mode (spICP-MS).

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.*
Introduction: Monitoring water quality in mobile dialysis (MD) services, assessing critical points and characterizing the risks inherent in the process, is essential to avoid risks to the patient's health. This study evaluated the microbiological quality of water in the MD of 36 hospitals with intensive treatment in the city of Rio de Janeiro.
Methods: 204 water samples were collected from the points of entry to the network (NET), post-osmosis (PO) and dialysis solution (DS).
