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 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 organisms are needed. TMPTA
is not expected to persist and/or adsorb to the soil matrix.
Consequently, no experimental studies are required. For the risk
assessment, PNEC is calculated by the Equilibrium Partitioning Method
