In accordance with
column 2 of REACH Annex IX, chapter 9.4., the study does not need to be
conducted if the substance does not have PBT properties. In addition, a
direct application of the thioglycolate anion to soil is not intented.
According to chapter R.7c of ‘Guidance on information requirements and
chemical safety assessment’ (ECHA, 2012), readily biodegradable
substances which are not directly applied to soil will not enter the
terrestrial environment and as such there is no need for testing of soil
organisms. In general, this is true for thioglycolic acid and its salts
which are considered to be readily biodegradable. Additionally, these
substances have only a low potential for adsorption to solids
considering their low log Pow of -2.99. Thus, even if soil would be a
compartment of indirect entry of the thioglycolate anion after
application of sewage sludge as fertiliser, it is expected that residues
within the sludge are negligible. In conclusion, tests with terrestrial
organisms are not relevant due to exposure considerations.
Studies with birds are
not needed as thioglycolic acid and its salts have only a low potential
for bioaccumulation based on their low log Pow and there is no
indication that the substance is toxic to mammals.
