Additional information

Data were taken from phenol dossier - read across appreach was chosen because the content of phenol in the registered substance could be up to 50% (w/w).

Conclusion on classification

Aquatic environment classification

Due to the high degradation rates within a period of < 10 days phenol is ready biodegradable in waste water, freshwater, sea water, and at anaerobic conditions with inoculum created from activated sludge.

The lowest acute EC/LC50 value in aquatic tests is the EC50 of 3.1 mg/L, based on measured initial concentrations, obtained in a static 48-h acute toxicity test with Ceriodaphnia dubia (Oris et al. 1991).

Due to the ready biodegradability of phenol and its low log Pow the substance is not classified as dangerous/hazardous for the environment according to Directive 67/548/EEC and according to the Regulation (EC) 1272/2008 on classification, labelling and packaging of substances and mixtures (CLP Regulation):

Lowest reliable L(EC)50 value:                 3.1 mg/L Daphnids

Ready biodegradable                                yes

log Pow                                                     < 3

Special concern:                                       no

 

According to 67/548/EEC Annex 1:      not classified

 

According to GHS:

Hazardous to the environment       not classified, no hazard statement

                                                      Reason for classification:    L(E)C50 1-10 mg/L; readily biodegradable, log Pow<4

Hazardous to the atmospheric environment:

(Hazardous to the ozone layer: This includes substances which are listed in Annex I to Regulation (EC) No 2037/2000 of the European Parliament and of the Council of substances that deplete the ozone layer (1) and its subsequent amendments):
Phenol is not listed in Annex I of (EC) No 2037/2000.
