Description of key information
No valid studies are available for SMCA.
One GLP study with MCA (Noack, 1992) showed a 72h-ErC50 of 0.033 mg/L and a 72h-ErC10 of 0.007 mg/L for Scenedesmus subspicatus.
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 0.033 mg/L
- EC10 or NOEC for freshwater algae:
- 0.007 mg/L
Additional information
Algae are very sensitive to MCA. Which is not surprising as MCA is a known herbicide.
Two valid studies are available for aquatic algae. One GLP study (Noack, 1992) showed a 72h-ErC50 of 0.033 mg/L and a 72h-ErC10 of 0.007 mg/L for Scenedesmus subspicatus. These results are supported by the study performed by Kuehn et al. (1990) where an EbC50 of 0.028 mg/L and an EbC10 of 0.007 mg/L were found.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
