After temperature adaptation of the test solutions the daphnids were transferred into the test solutions by using an upside-down glass pipette. No feeding during the test. No aerationof test vessels.

- yes
- Remarks:
- potassium dichromate
- Duration:
- 48 h
- Dose descriptor:
- EC50
- Effect conc.:
- > 137 mg/L
- Nominal / measured:
- nominal
- Conc. based on:
- test mat.
- Basis for effect:
- mobility
- Details on results:
- No immobilisation or behavioural abnormalities were observed in the control and the water-accommodated fraction at a loading rate of 100 mg Bismuth/L (137 mg test item/L).
The measured (dissolved) concentrations of Bismuth were below the limit of detection (LOD: 0.0375 mg Bi/L; 0.051 mg test item/L) in all samples. - Results with reference substance (positive control):
- The reference test with potassium dichromate performed in may 2010 resulted in an 24h-EC50 of 0.66 mg/L. According to the OECD guideline 24h-EC50 guideline values should range between 0.6 and 2.1 mg/L. The toxicity of the reference item is within this range.
- Reported statistics and error estimates:
- No statistical method was used to evaluate the daphnid immobilities because no immobilities were observed during the test period in the control or the test item treatment.
- Validity criteria fulfilled:
- yes
- Conclusions:
- GLP test according to OECD guidelines. No effect was observed in a limit test with the water-accommodated fraction at a loading of 137 mg/L test item (100 mg Bi/L) and therefore the 48h-EC50 for immobilization of Daphnids is > 137 mg/L test item (>100 mg Bi/L).
- Executive summary:
This was a GLP test according to OECD guidelines using a related substance, bismuth subnitrate. No effect was observed in a limit test with the water-accommodated fraction at a loading of 137 mg/L test item (100 mg Bi/L) and therefore the 48h-EC50 for immobilization of Daphnids is > 137 mg/L test item (>100 mg Bi/L).

Additional information
Two reliable GLP-conform studies according to the OECD 202 guideline are available for the acute toxicity of Bi subnitrate and Bi metal to Daphnia magna. Egeler et al. (2010) studied the effect of the water accommodated fraction of bismuth subnitrate (Bi5O(OH)9(NO3)4) after seven days equilibration on the immobility of Daphnia magna. A limit test did not show any immobilisation or behavioural abnormalities in the control and the water-accommodated fraction at a loading rate of 100 mg Bismuth/L (137 mg test item/L). The EC50 (48 h) was therefore determined to be higher than 100 mg Bi/L. The measured dissolved Bi concentration was in all treatments below the limit of detection (0.0375 mg Bi/L). In a second limit test, also no effect of Bi metal was found on mobility of Daphnia magna (Neven, 1995) at 100 mg Bi/L (measured dissolved concentration is concentration is <0.05 mg Bi/L).
No data are available for the short-term toxicity of bismuth to marine invertebrates.
