Choiniere explained, It’s a bit different with infants and children, where even low-level exposure to arsenic has been associated with neurodevelopmental issues. . . . Arsenic may also harm pregnancy and boost infant mortality rates. When a baby is exposed to inorganic arsenic in utero, there’s an increased risk of cancer, lung disease, heart attacks, and kidney failure. Recent studies also suggest that arsenic exposure in utero may have effects on the baby's immune system.
