investigations considering possible toxic effects of
1,3,4-Thiadiazolidine-2,5-dithione, reaction products with hydrogen
peroxide and tert-nonanethiol towards terrestrial organisms are waived.
A reliable Koc of > 4.27 x 10E5 (OECD 121, Fox, 2012) is available for
the test substance and the required PNECsoil was derived using the
Equilibrium Partitioning Method (EPM) described in ECHA Guidance R.10
(Guidance of Information Requirements and Chemical Safety Assessment,
Chapter R.10: Characterisation of dose-response for environment, therein
chapter R.10.6.1, 2008). It is considered that the information available
is sufficient and further testing is not required. If necessary, data
available from aquatic toxicity testing can be used as a worst case
scenario if further characterization of the terrestrial compartment is
desired. Hence, it is concluded that this substance exhibit relevant
ecotoxicity potential in soil organisms.
