Conclusion on classification

Aquatic environment classification

Cumene proved to be readily biodegradable (> 60 % biodegradation after 10 days).

The lowest acute EC/LC50 value in aquatic tests is the EC50 of 1.2 mg/L for Mysidopsis bahia.

The lowest reliable long-term effect value in aquatic studies is the 21 d NOEC of 0.35 mg/l for Daphnia magna.

Basic data for classification:

Lowest reliable acute L(EC)50 value:       1.2 mg/L forMysidopsis bahia

Lowest reliable long-term NOEC value:    0.35 mg/l forDaphnia magna

Biodegradability:                                       readily biodegradable

log Pow                                                    < 4

Special concern:                                        no

 

Legal classification according

to 67/548/EEC Annex 1:                       Dangerous for the environment: N, R51/53 (classified as not readily biodegradable in RAR)

Legal classification according to Commission Regulation (EU) No 286-2011 of 11 March 2011 amending, for the purposes of its adaptation to technical and scientific progress, Regulation (EC) No 1272/2008:

Classification:                                            Aquatic Chronic 2 (H411)

Labelling:                                                  Signal word: Dangerous for the environment;

Pictogram for environmental hazards:        GHS09

Reason for classification:                            NOEC: 0.1 – 1 mg/L; not readily biodegradable

Self-classification according toCommission Regulation (EU) No 286-2011 of 11 March 2011 amending, for the purposes of its adaptation to technical and scientific progress, Regulation (EC) No 1272/2008:

Classification:                                            Aquatic Chronic 3 (H412)

Labelling:                                                  no pictogram, no signal word

Reason for classification:                            NOEC: 0.1 – 1 mg/L; readily biodegradable

Hazard 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 ofon substances that deplete the ozone layer (1) and its subsequent amendments):

cumene is not listed in Annex I of (EC) No 2037/2000.
