Description of key information
Additional information
Aquatic Toxicity:
Methyl-ethylketone peroxide was tested for aquatic toxicity in a number of tests including EU-Method C.1, Acute toxicity to fish, EU-Method C.2, Acute toxicity to Daphnia and EU-Method C.3, Acute toxicity to algae.
Fish:
Acute toxicity to fish in the test with Poecilia reticulata (guppy) revealed a 96 h-LC50 of 44.2 mg/L. The NOEC after 96 hours was 18 mg/L, whereas 100 mg/L produced 100% mortality within 24 hours.
Daphnia:
Acute toxicity to aquatic invertebrates in the test with Daphnia magna revealed a 48 h-EC50 of 39 mg/L.
The NOEC after 24 hours was 26.7 mg/L.
Algae:
Acute toxicity to algae in the test with Pseudokirchneriella subcapitate revealed a 72 h-EC50 (growth rate) of 5.6 mg/L and 72 h-EC50 (cell growth) of 3 .2 mg/L. Furthermore, a 72h-EC50 (growth rate) of 2.1 mg/L and a 72 h-EC50 (cell growth) of 1.7 mg/L. The 72 h-NOEC (cell growth and growth rate) was 2.1 mg/L.
Toxicity to microorganisms:
The toxicity of methyl-ethylketone peroxide to microorganisms was tested in activated sludge respiration inhibition test. The EC 50 (30 min) was determined to be 48 mg/L (nominal concentration).
Long-term toxicity testing to fish and aquatic invertebrates was waived based on ready biodegrability and very limited exposure to the environment, if any.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
