Toxicity to aquatic algae and cyanobacteria
Administrative data
Link to relevant study record(s)
Description of key information
Toxicity to aquatic algae was studied on Chlorella pyrenoidosa for 72 hours. The lowest observed adverse effect concentration (LOAEC) and no-observed adverse effect concentrations (NOAEC) for N, N-dimethylaniline were found to be 22 mg/L and 14 mg/L respectively.
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 22 mg/L
- EC10 or NOEC for freshwater algae:
- 14 mg/L
