Key value for chemical safety assessment

Additional information

To determine chronic effects of Hydrogenation products of 4-[(4-amino-3-methyl-phenyl)methyl]-2-methyl-aniline (CAS 6864 -37 -5, DMDC) on aquatic invertebrates, a GLP-study according to OECD 211 (21 d-reproduction test) was performed with Daphnia magna. The test concentrations were analytically verified. The mean measured concentrations for the whole exposure period were within ±20% of the nominal concentration. The NOEC was determined to be 4.0 mg/L (reproduction; nominal) (NITE Japan, 2003; NMMP/E00/3090). All validity criteria were fulfilled in this study. Based on the NOEC of 4.0 mg/L chronic effects on aquatic invertebrates are not expected.
