Witryna5 wrz 2015 · Two fractions of OBT can be distinguished: bound to oxygen and nitrogen atoms as an exchangeable organically bound tritium (E-OBT), or bound to carbon atoms as a non-exchangeable organically bound tritium (NE-OBT) [ 1 – 4 ]. The exchangeable OBT is considered to be in equilibrium with the HTO in plants.
