It is expected that PNECs of aquatic organisms and STP (Sewage Treatment Plant) in REACH dossiers were more accurate than those in the existing chemical assessment documents because the ecological risk assessment in REACH legislation would be carried out after data gap was filled. However, many PNECs for freshwater aquatic organisms in the published 26 REACH dossiers were diverted from the short-term testing, or were derived from the existing documents. Some PNECs of STP were derived from the newly conducted tests. As a result, there was rarely difference between the ecological risk assessment in REACH and in the existing chemical assessment documents.
