Table 1. Summary of findings.
No reliable, standard tests of terrestrial arthropods are available.
Effects on F. candida: (7 d) EC50 530 mg/kg soil dw is available from a
study of non assignable reliability. Long term: In accordance with
Column 2 of REACH Annex X the study does not need to be conducted.
A 7 d EC50 value of 530 mg/kg dw soil (1.3% organic carbon)
has been determined for the effects of the test substance on population
numbers of the Fulsomia candida (Shell, 2004).
This study reflects the only value that is available for this endpoint,
though it is of non assignable reliability.
In accordance with Column 2 of REACH Annex X, long-term toxicity testing
with terrestrial invertebrates (required in Section 9.4.4) is not needed
as the chemical safety assessment according to Annex I indicates that
this is not necessary.
Moreover, considerable technical difficulties would be expected in
the conduct of such a test, due to the very rapid biotic removal of the
substance from the test system. Please refer to discussion of the
long-term aquatic invertebrate and fish studies, and evidence of rapid
removal in non-sterilised soils during method development for the
adsorption/desorption study with natural soils in the environmental fate
