Description of key information

In accordance with column 2 of REACH Annex IX, terrestrial toxicity studies does not need to be conducted as the registered substance is not supposed to be directly applied to soil and an indirect exposure to soil via sewage sludge transfer is unlikely since the substance is readily biodegradable. Indeed, the substance will be biodegraded within the STP process and as a consequence a transfer to the soil compartment is not expected. In addition, with a log Kow value lower than 3.0 (=2.61), a significant distribution into the soil compartment and a significant exposure of terrestrial organisms is not expected. Finally, based on a conservative estimation from Chesar, the chemical safety assessment of the substance indicates no need to investigate terrestrial testing. Hence, information about effects on terrestrial organisms is not required and the Equilibrium Partitioning Method (EPM) has been used for assessing the hazard to terrestrial organisms.
