Short-term toxicity to aquatic invertebrates
Some information in this page has been claimed confidential.
Administrative data
- Endpoint:
- short-term toxicity to aquatic invertebrates
- Type of information:
- experimental study
- Remarks:
- One guideline study (OECD 202) is available for short-term toxicity in invertebrates. The GLP status is unclear. The 48-h EC50 in Daphnia magna is 156 mg/L in a static test; no analytical monitoring has been performed
- Adequacy of study:
- key study
- Study period:
- 2003
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: : GLP status unclear, guideline study, available as unpublised report, minor restrictions, adequate for assessment. However, no analytical monitoring has been performed and the purity of the test substance was not specified.
Cross-reference
- Reason / purpose for cross-reference:
- read-across source
- Remarks:
- In the following is the data from the study available to determine the short-term toxicity of trisodium hexafluoroaluminate on aquatic invertebrates.
Reference
No studies are available to determinate the toxicity to aquatic plants other than algae, of trisodium hexafluoroaluminate or calcium fluoride. Available studies on fluoride were used as read-across source. Effective concentrations were recalculated taking in account the different molecular weight of the source and target substance.
A 7 -day study was conducted on Lemna minor to assess the toxicity of fluoride in the presence of chloride and in hard water. Lemna minor was found to be relatively insensitive to fluoride with an IC50 value (frond number) of 391 mg/L F. This relates to 803.39 mg CaF2/L. and relates to 720 mg Na3AlF6/L
Reliable acute ecotoxicity test results are available for fish, invertebrates and algae. The 96-h LC50 in Brachydanio rerio is 99 mg/l from a GLP compliant OECD guideline study (Solvay, 2008a). An OECD guideline study is available for short-term toxicity in invertebrates, the 48-h EC50 in Daphnia magna is 156 mg/l (IWL, 1998). The 72-h ErC50 is 8.8 mg/l in the freshwater algae Pseudokirchneriella subcapitata (tested as Selenastrum capricornutum), the 72-h NOEC for growth rate is 1.0 mg/l from a GLP compliant OECD guideline study (Solvay, 2008b).
Long-term ecotoxicity tests with fish and invertebrates are not available.

Results and discussion
Effect concentrations
- Key result
- Duration:
- 48 h
- Dose descriptor:
- EC50
- Effect conc.:
- 156 mg/L
- Nominal / measured:
- nominal
- Conc. based on:
- test mat.
- Basis for effect:
- other: : immobilisation
- Details on results:
- Immobilisation in control vessels (0 mg/l) remained under 10 %. EC50 of 156 mg/l (above observed water solubility) was extrapolated from the test.
- Results with reference substance (positive control):
- The EC50 with kaliumdichromat was 1.8 mg/l
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Conclusions:
- Because in RAL 3.0 Trisodium hexafluoroaluminate is present in a proportion of less than 1%, the preparation is not harmful to aquatic invertebrates
- Executive summary:
One guideline study (OECD 202) is available for short-term toxicity in invertebrates. The GLP status is unclear. The 48-h EC50 in Daphnia magna is 156 mg/L in a static test; no analytical monitoring has been performed
