Description of key information
A reliable key study is available on algae: An OECD 201 study on Pseudokirchneriella subcapitata on the commercial product (60 % aqueous solution) gives an 96h-EC50 value of > 100 mg/l and a 96h-NOEC of = 31.6 mg/l . Trend in growth rate shows that EC50 of pure substance N-methylol methacrylamide will be within the range of 10-100 mg/l.
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 100 mg/L
- EC10 or NOEC for marine water algae:
- 31.6 mg/L
