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 a substance being considered as „readily biodegradable“, it can be assumed that it will be biodegraded within the STP process and as a consequence atransfer to the soil compartment is not expected. Furthermore asthe logKoc is below 3 and the substance has no cationic properties, a low adsorption potential is indicated. Therefore, binding to sewage sludge is unlikely and as a consequence a transfer to the soil compartment is not expected. Therefore, no tests on terrestrial organisms are provided.

For the classified impurity naphthalene, an EPM derived PNEC for soil is available and described in the European Risk Assessment Report No. 33 on Naphthalene, CAS-No. 91 -20 -3. In a risk assessment for the naphthalene impurity in NSA no risk has been revealed.
