Description of key information

Additional information

No terrestrial toxicity data are currently available for the registered substance. Soil toxicity studies are not required for Annex VII substances under the REACH Regulation. However, due to the high adsorption potential of the substance, the potential significance of this compartment has been assessed qualitatively.

The registration substance has an extremely low water solubility (5.8E-05 mg/L) and very high log Kow (9.0). These values indicate that the equilibrium between dissolved substance in soil interstitial water and adsorbed substance on soil solids will be significantly in favour of the adsorbed form and assumed to be non-bioavailable. At equilibrium, the solids : water weight ratio is such that exposure via the interstitial water would be very low in absolute terms and also as a fraction of the total applied to soil. The feasibility of studying the parent substance in a standard study is also uncertain.

In case of a tonnage upgrade in future, necessitating a quantitative exposure assessment, the approach for terrestrial ecotoxicity endpoints will be revisited.
