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 day
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Remarks:
- Peer Reviewed publication
- Justification for type of information:
- As with all inorganic salts, the significance for toxicity or environmental assessment is the presence of specific ions that will form when in solution or when in biological systems.In the case of Cr III salts, the counter ion will have an effect on solubility and this is itself dependant on the type of media being used and in particular the pH of that media. It is generally accepted that in the case of metal salts, testing with salts that are soluble in the respective test media will ensure maximum exposure of the metal ions. This will include chlorides and nitrates as being more soluble and will indeed have relevance when dissolved in acid media, such as if ingested.Read-across to other chromium III salts is therefore considered valid as long as the exposure in the test system is greater than would be expected for the substance under review for registration.

- Executive summary:
Investigations were carried out in order to determine the “no observed effect concentration” (NOEC) of 73 environmentally relevant substances in the 21 d Daphniareproduction test. The test was conducted in line with the provisional procedure proposed by the Federal Environmental Agency (Umweltbundesamt) (as of 1 January 1984). Daphnia magna Straus was used as the test organism. Evaluation parameters for fixing the NOEC were the mortality of the parent animals, the reproduction rate and the appearance of the first offspring during the test period. The concentrations of substances in the test preparations were chemically quantified.
The 21 day NOEC (reproduction) for chromium 3+ was 0.7 mg/l and 24 hr EC50 (immobilisation) was 22 mg/l.
Reference
24 hour EC50 reported as 22 mg/l Cr3+ (ca 45 mg/l CrF3)
Description of key information
The 21 day NOEC (reproduction) for chromium 3+ was 0.7 mg/l and 24 hr EC50 (immobilisation) was 22 mg/l.
The NOEC for CrF3 is estimated ca 1.5 mg./l
