Haigh hair selenium as an indicator of mother to fetus placental transfer from Brazil nuts (Bertholletia excelsa)

A pregnant woman in the last trimester of gestation incidentally consumed a package of Brazil nuts (Bertholletia excelsa) over one week period. Two months after delivery of a healthy baby daughter, the hair multielement profile analysis revealed a grossly increased hair selenium concentration of 2.70 in the mother and 9.74 ng.g-1 in the daughter. Adequate hair Se concentration of a Croatian woman population range 0.08 - 0.63 ng.g-1. There is a substantial capacity of gastrointestinal absorption and trans- placental transfer of dietary Se from a pregnant mother to the fetus and Se accumulation in the hair of both mother and fetus.
