Administrative data
Link to relevant study record(s)
Description of key information
The EC50 based on growth rate was determined to be > 120 mg/L. The NOEC based on
growth rate as well as on biomass was 120 mg/L. Testorganism was Scenedesmus subspicatus.
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 120 mg/L
- EC10 or NOEC for freshwater algae:
- 120 mg/L
Additional information
The toxicity of methyl acetate to algae was tested in a static test system for a test period of 72 h according to OECD 201. Scenedesmus subspicatus was the test organism. The test was conducted as a limit test with a test concentration of 120 mg/L. The EC50based on growth rate was determined to be > 120 mg/L, based on nominal values. The NOEC based on growth rate as well as on biomass was 120 mg/L.
Key values actaully are "> 120 mg/l" each, but IUCLID does not allow to enter ">" in these fields.
A study with marine water algae is not available.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
