Description of key information

Based on the toxicity of the source substances, the target substance predicted aquatic toxicity values are:

 

96-hr LC50 (fish) >3,000 mg/L based on 2 -aminoethanol and approximately 70 mg/L based on propionic acid.  For risk assessment the conservative 96-hr LC50 (fish) = 70 mg/L will be utilised.

 

48-hr LC50 (daphnid) of 226 mg/L based on 2-aminoethanol and 67 mg/L based on propionic acid.  For risk assessment the conservative 48-hr LC50 (daphnid) = 67 mg/L will be utilised.

 

72-hr EC50 (algae) of 24 mg/L based on 2-aminoethanol and 65 mg/L based on propionic acid.  For risk assessment the conservative 72-hr ErC50 (algae) = 24 mg/L will be utilised.

 

3-hr NOEC (ASRIT) >1,613 mg/L based on 2-aminoethanol and 17-hr EC10 (P. putida) 60 mg/L based on propionic acid.  For risk assessment the conservative 17-hr EC10 (P. putida) 60 mg/L will be applied, as this value derives the more protective PNEC (STP) value.
