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
