Additional information

The test substance is not supposed to be directly applied to soil and an indirect exposure to soil via sewage sludge transfer is unlikely since the substance is readily biodegradable. For substances being considered as readily biodegradable, it can be assumed that they will be biologically degraded within the STP process. In special cases, if the substance is not entering the STP process but is readily biodegradable, it can be assumed that it will be rapidly biological degraded in the surface water. In both cases, a transfer to the soil compartment is unlikely.

The predicted no effect concentration (PNEC) for soil was derived from the PNEC for freshwater using the equilibrium partitioning method. Using this PNECsoil, the risk characterization revealed that the PEC/PNECsoil ratio (RCRsoil) is <1, indicating no need for further information and testing.

Therefore, no tests on terrestrial organisms are provided.
