This finding was consistent with
an active transport mechanism across the placenta. Others have
suggested that nitrate or the reduced form (nitrite) may pass to the
fetus through a system of active transport similar to that of iodide,
and fetal nitrate plasma levels may exceed that of the mother (Hartman
1982). Interestingly, from a separate questionnaire sent home for
parents to complete, the majority of parents (77%) stated they either
walked or cycled to school themselves as 10-year-olds, indicating a
substantial decrease in active transport in only one generation. |
