Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

Two reliable GLP-conform studies (Klimisch 1) 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.
