Description of key information

Toxicity testing in terrestrial arthropods is waived, in accordance with Regulation (EC) No.1907/2006, Annex IX, Column 2.

Key value for chemical safety assessment

Additional 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. Although the substance exhibits a high potential to adsorb to soil (the experimentally-determined adsorption coefficient (Koc) ranged from 60,000 L/kg to > 832,000 L/kg in tests on five soil types), the substance has been shown to degrade rapidly in soil and other environmental compartments. 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. Therefore, toxicity testing on terrestrial arthropods is not indicated.
