Additional information

Waiving argument:

In accordance with column 2 of REACH Annex X, the study on sediment organisms does not need to be conducted as direct and indirect exposure of the sediment compartment is unlikely.

A supporting argument is that for substances being considered as „readily“, it can be assumed that they will be completely biologically degraded within the STP process. Furthermore, for substances not passing the STP-process but being readily, it can be assumed that they will be also biological degraded in the surface water within a short time. PNECs for sediment organisms have been derived using the EPM method.
