Additional information

In accordance with column 2 of REACH Annex X,studies on effects on terrestrial organisms do not need to be conducted if direct and indirect exposure of the soil compartment is unlikely. Based on the use pattern for this substance that it is readily biodegradable, direct and indirect exposure of soil is unlikely. The equilibrium partitioning method is considered adequate to estimate the toxicity to soil macro-organisms using the existing aquatic toxicity hazard data. This method is applicable for substances where the toxicity in soils relates to the freely dissolved concentration in pore water, which is the case here, as this substance has low adsorptive potential. Based on this and the low predicted exposures in soil and the fact that good data is available for the aquatic compartment, it is assessed that no toxicity testing to soil macroorganisms are needed.
