Key value for chemical safety assessment

Additional information

The results as presented by Calamari and co-workers in 1980 indicate that tert-butylamine is probably not acutely harmful to daphnids. The IC50 (24 h) based on mobility was determined to be 136 mg/L and was based on analytically determined test item concentrations. No information is given concerning whether the test item solutions were neutralised or not.
