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
