No studies on toxicity to soil macroorganisms are available for propylene glycol methyl ether acetate.
The risk characterisation shows that the
PEC/PNEC ratio for soil is clearly < 1, indicating no need for
further information and testing. Propylene glycol methyl ether acetate
is highly water soluble (completely miscible) and has a very low
potential for adsorption to organic matter. Therefore, the predicted no
effect concentration (PNEC) for soil was derived from the PNEC for
freshwater using the equilibrium partitioning method. This method is
applicable for substances where the toxicity in soils relates to the
freely dissolved concentration in pore water. The distribution modelling
(Mackay level III fugacity modeling) indicates that when propylene
glycol methyl ether acetate is released to air, the substance will react
with hydroxyl radicals. If released directly to water, most of the
substance will remain in the water compartment and is expected to be
biodegraded. If released to soil, the substance is expected to be
biodegraded. Hence testing of effects on terrestrial organisms can be
waived for propylene glycol methyl ether acetate.
