Additional information
For N-(1,1,3,3-tetramethylbutyl)acrylamide, data are available for fish, Daphnia and algae. An overview of all results is presented in the table below.Concentrations were analysed and remained stable in all short term and chronic studies (90-107% of nominal), so all results are reported as nominal concentrations.
The name of the green algae was reported as Selenastrum capricornutum. In the table the new name Pseudokirchneriella subcapitata is used.
An overview of all results is presented in the table below:
