Description of key information

According to Regulation (EC) No.1907/2006, Annex IX, Column 2, toxicity testing on terrestrial organisms need not be conducted if direct and indirect exposure of the soil compartment is unlikely.  The substance does not have a high potential to adsorb to soil, based upon its soil adsorption coefficient (Koc) of 307.2 L/kg (i.e., log Koc = 2.49), which is below the criterion that is indicative of strong binding to soil (i.e, log Koc > 4, in accordance with ECHA guidance).  The hazard associated with exposures of the substance to terrestrial organisms was evaluated in the chemical safety assessment on the basis of a predicted no-effects level calculated from aquatic toxicity levels and equilibrium partitioning.  The chemical safety assessment indicated that terrestrial exposures do not require further investigation; the risk characterisation ratios for soil are below one.  Therefore, in accordance with Annex I, the risks are considered to be controlled, and direct and indirect exposures of terrestrial organisms to the soil are unlikely.
