Which contaminant poses a specific, high risk to the developing nervous systems of fetuses and young children?
Answer
Methylmercury
Methylmercury is identified as a potent neurotoxin whose effects are most concerning when exposure occurs during critical periods of development. This toxin is particularly dangerous because it readily crosses biological barriers, specifically the placenta in developing fetuses and, subsequently, is secreted into breast milk. High exposure levels during these times can seriously impede or damage neurological development in infants and young children, leading health organizations to issue strict consumption guidelines for vulnerable groups.
