Fast abiotic sorption of selenates (SeO42-) in soils: pitfalls of batch sorption data acquired by inductively coupled plasma quadrupole mass spectrometry (ICP-QMS)
Original language description
Low selenium (Se) dietary intake has encouraged the development of fortification strategies such as SeO42- application to arable land. Selenate is highly mobile in soils, but it is not known whether fast abiotic retention could reduce Se loss from topsoil after SeO42- fertilisation. This work aims at abiotic SeO42- sorption in three soils exposed to 20-1250 ug L-1 Se in a 24-h batch experiment. The distribution coefficient (Kd), not exceeding 2 L kg-1 at any Se level, was shown to be a useful indicator for the extent of ion competition for sorption sites depending on the SeO42- concentration employed. Sorption experiments in the presence or absence of nitrate (10 mM), sulphate (0,52 mM) and phosphate (0,21 mM) allowed three phenomena explaining different SeO42- retention behaviours found even between similar Cambisols to be proposed. Finally, we showed that the co-application of sulphate or phosphate with SeO42- might decrease Se sorption from 150-170 ug kg-1 to a net release from native Se pool.
