The simulation test on ultimate degradation in surface water and
sediment simulation test study required in REACH guidance, Annex IX
(Sections 220.127.116.11 and 18.104.22.168) do not need to be conducted as the
substance is readily biodegradable. The chemical safety assessment also
indicates that the identification of degradation products (required in
section 9.2.3) is not necessary.
However, in a reliable simulation in water and sediment test conducted
in accordance to OECD 303A, a value of 93 ± 5 % has been determined for
Citric acid. The observed removal could be due to adsorption and/or
degradation. The read across from citric acid to trizinc dicitrate is
justified on the basis that the effect of trizinc dicitrate is not
expected to significantly differ from the effects of the citrate anion
and the metal ion in solution.
