Description of key information

In this study, the acute toxicity of Jeffamine RFD 270 to Pseudokirchneriella was investigated in a 72-h static study (nominal concentrations between 0-1 mg/L). This results in a 72-h ErC50 of 0.16 mg/L.

Key value for chemical safety assessment

EC50 for freshwater algae:
0.16 mg/L
EC10 or NOEC for freshwater algae:
0.071 mg/L

Additional information

The algae growth inhibition study of Vrijenhoef (2012) was used as key study for PNEC derivation. The 72-h test was conducted according to OECD guideline 201. The nominal test concentrations were between 0 -1 mg/L. A 72-h ErC50 of 0.16 mg/L for Pseudokirchnerialla subcapitata was obtained in this study. The 72-h ErC10 was 0.071 mg/L. This indicates that Jeffamine RFD 270 is very toxic to aquatic algae.
