Description of key information

Toxicity to green algae predicted from a scientifically valid (Q)SAR model: 
- 96h-EC50 = 0.009 mg/l (Kovarich, 2014)
- 96h-NOEC ≤ 0.004 mg/l (Kovarich, 2014)

Key value for chemical safety assessment

EC50 for freshwater algae:
0.009 mg/L
EC10 or NOEC for freshwater algae:
0.004 mg/L

Additional information

For the determination of the toxicity of Tetradecylamine to aquatic plants, one short-term toxicity data and one long-term toxicity data are reported from (Q)SAR predictions based on a scientifically valid model: ECOSAR. This models fulfils the characterisation criteria specified in the OECD Guidance Document on the validation of (Q)SAR models.

A short-term 96h-EC50 of 0.009 mg/l and a long-term 96h-NOEC ≤ 0.004 mg/l (ChV = 0.004 mg/l) are predicted for Tetradecylamine towards green algae; both predictions are considered reliable with restrictions (Klimisch 2) and are used a key values for the assessment.
