Long-term toxicity to aquatic invertebrates
Administrative data
Link to relevant study record(s)
- Endpoint:
- long-term toxicity to aquatic invertebrates
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 21 days
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Justification for type of information:
- Data refers to sodium salt.
Triethanolamine is not classified as hazarodus in the environment and the sodium salt is considered a suitable surrogate for read-across
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 211 (Daphnia magna Reproduction Test)
- GLP compliance:
- yes (incl. QA statement)
- Analytical monitoring:
- yes
- Vehicle:
- no
- Test organisms (species):
- Daphnia magna
- Test type:
- semi-static
- Water media type:
- freshwater
- Limit test:
- no
- Total exposure duration:
- 21 d
- Nominal and measured concentrations:
- Maximum nominal concentration 10 mg/l actives (33.5 mg/l as supplied)
The maximum concentration was based on results from acute teting that showed an effect on survival at 10 mg/l - Duration:
- 21 d
- Dose descriptor:
- NOEC
- Effect conc.:
- ca. 10 mg/L
- Nominal / measured:
- nominal
- Conc. based on:
- act. ingr.
- Basis for effect:
- reproduction
- Details on results:
- No adverse effects at maximum tested concentration
- Validity criteria fulfilled:
- yes
- Conclusions:
- NOAEC > 10 mg/l actives. This figure has been used for estimating PNEC
- Executive summary:
It is predicted that the triethanolamine salt will have a lower toxicity in view of the low biological effect of triethanolamine and the molecular weight difference between triethanolamine and sodium; however, due to uncetainty factors in read-across, it is assumed that the toxicity of the triethanolamine salt will be equivalent to that of the sodium salt.
Reference
Description of key information
Daphnia reproduction study (2013) NOAEC was 10 mg/l actives (the highest concentration tested), showing a very narrow threshold between acute and chronic toxicity. Supporting analysis confirmed stability of the substance in the test system.
Key value for chemical safety assessment
Fresh water invertebrates
Fresh water invertebrates
- Effect concentration:
- 10 mg/L
Additional information
No effect level in the reproduction study was slightly higher than that reported in an earlier acute test.
