Description of key information

Data concerning the long-term toxicity of (1-methylethyl)-1,1'-biphenyl to aquatic invertebrates are not available. Instead test results with the supporting substance 4-ethylbiphenyl are used.

Key value for chemical safety assessment

EC10, LC10 or NOEC for freshwater invertebrates:
0.028 mg/L

Additional information

As data regarding the long-term toxicity of (1-methylethyl)-1,1'-biphenyl to aquatic invertebrates could not be identified, test results of the supporting substance 4-ethylbiphenyl will be used. 4-Ethylbipenyl was tested in a valid study according to OECD TG 211 (CHRIP/NITE 1999). The 21 d NOEC and EC50 were determined to be 0.028 mg/L and 0.082 mg/L, respectively.
