Toxicity to aquatic algae and cyanobacteria
Administrative data
Link to relevant study record(s)
Description of key information
Based on this result, tripropylamine is considered acutely harmful to aquatic organisms.
However, a new study is planned based on ECHA communication/decision number CCH-D-2114585925-31-01/F.
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 22.4 mg/L
- EC10 or NOEC for freshwater algae:
- 9.03 mg/L
Additional information
Possible toxic effects of tripropylamine to aquatic algae were investigated in a study with Desmodesmus subspicatus according to the German Standard Guideline DIN 38412, L9. Nominal concentrations were 0, 5, 10, 25, 50, 100 and 250 mg/L (no analytical monitoring). Following effect values were determined for growth rate after 72 h: ErC10 = 9.03 mg/L, ErC50 = 22.4 mg/L (BASF AG, 1989, Rep. no. 89/1742).
Based on this result, tripropylamine is considered acutely harmful to aquatic organisms.
However, a new study is planned based on ECHA communication/decision number CCH-D-2114585925-31-01/F.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
