In accordance with REACH Annex XI, the study
does not need to be conducted as in water sodium carbonate is
dissociated into sodium and carbonate ions and both ions will not adsorb
on particulate matter. Therefore, direct and indirect exposure of the
soil compartment, via the use of sludge of an STP, is unlikely.
Furthermore, it should be realised that sodium carbonate is naturally
present in soil and toxicity for terrestrial plants is expected to be
Few reliable studies are available exposing
different species of plants to Na2CO3. Overall,
the different authors expose the plants via water irrigation or using
and hydroponics system, growing plants in a water based nutrient rich
solution, hence all
available data are
express in terms of mg/L
rather than mg/kg soil.
Here is presented a summary table of the results:

Li et al., (2017)
seeds of the bitter vetch, Vicia ervilia
