Short-term toxicity to aquatic invertebrates
Administrative data
Link to relevant study record(s)
- Endpoint:
- short-term toxicity to aquatic invertebrates
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 48 hours
- 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:
- EU Method C.2 (Acute Toxicity for Daphnia)
- GLP compliance:
- yes
- Analytical monitoring:
- no
- Details on sampling:
- Substance known to be stable in water (supplied in solution).
- Test organisms (species):
- Daphnia magna
- Details on test organisms:
- Test organism: Daphnia magna
Source: Shell Research Laboratories - Test type:
- static
- Water media type:
- freshwater
- Limit test:
- no
- Total exposure duration:
- 48 h
- Hardness:
- The stocks of animals were cultured, and the tests performed, in dechlorinated mains tap water, of typical hardness 280 mg/l CaC03
- Test temperature:
- The water was adjusted to 20 ± 1°C
- pH:
- pH stabilised between 7.0 and 8.0
- Dissolved oxygen:
- Aerated until the dissolved oxygen concentration reached a minimum of 60% air saturation
- Nominal and measured concentrations:
- A preliminary study had indicated the 48 hour ECso was approximately 100 mg/l (as supplied, 30 mg/l actives) and therefore definitive test concentrations were prepared as 10, 25, 63, 160, 400 and 1000 mg/I of material supplied
- Duration:
- 24 h
- Dose descriptor:
- NOEC
- Effect conc.:
- ca. 7.5 mg/L
- Nominal / measured:
- nominal
- Conc. based on:
- act. ingr.
- Basis for effect:
- mobility
- Duration:
- 48 h
- Dose descriptor:
- NOEC
- Effect conc.:
- ca. 3 mg/L
- Nominal / measured:
- nominal
- Conc. based on:
- act. ingr.
- Basis for effect:
- mobility
- Duration:
- 24 h
- Dose descriptor:
- EC50
- Effect conc.:
- ca. 55 mg/L
- Nominal / measured:
- nominal
- Conc. based on:
- act. ingr.
- Basis for effect:
- mobility
- Duration:
- 48 h
- Dose descriptor:
- EC50
- Effect conc.:
- ca. 29 mg/L
- Nominal / measured:
- nominal
- Conc. based on:
- act. ingr.
- Basis for effect:
- mobility
- Validity criteria fulfilled:
- yes
- Conclusions:
- Wide range of concentrations between those showing no effect and those leading to 100% immobilisation with increase in immobility over time.
A Daphnia reproduction study has been commissioned to look for potential chronic effects. - Executive summary:
The 48 hour ECso value of Lakeland AMA to Daphnia magna was estimated as 97.7 mg/l as supplied (29 mg/l actives).
The highest no-observed effect concentration (HNEC) after 48 hours was 10 mg/l (3 mg/l actives).
The lowest test concentration which immobilised all twenty Daphnia (LOEC) within 48 hours was 400 mg/l (120 mg/l actives).
Reference
The 48 hour ECso value of Lakeland AMA to Daphnia magna was estimated as 97.7 mg/l as supplied (29 mg/l actives). The highest no-observed effect concentration (HNEC) after 48 hours was 10 mg/l (3 mg/l actives). The lowest test concentration which immobilised all twenty Daphnia (LOEC) within 48 hours was 400 mg/l (120 mg/l actives).
The water quality measurements of the test solutions are given in Table 1 and were within acceptable limits. None of the twenty control Daphnia, maintained in dilution water, was immobilised during the study and this indicates an acceptable level of "health" of the test organisms cultured under the test conditions.
Description of key information
Acute Daphnia study performed, but no supporting analysis. However, substance known to be stable in water (supplied in solution).
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
No further animal testing can be justified.
Key value for chemical safety assessment
Fresh water invertebrates

- Effect concentration:

Additional information
The 48 hour ECso value of Lakeland AMA to Daphnia magna was estimated as 97.7 mg/l as supplied (29 mg/l actives). The highest no-observed effect concentration (HNEC) after 48 hours was 10 mg/l (3 mg/l actives). The lowest test concentration which immobilised all twenty Daphnia (LOEC) within 48 hours was 400 mg/l (120 mg/l actives).
Note that in a subsequent Daphnia reproduction study (2013), the 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.
