Short-term toxicity to aquatic invertebrates
Administrative data

Description of key information
48h EC50 of chromium trinitrate to daphnia magna ranged from 76.9 mg/L to 268.6 mg/L under the various hardness (from 52 to 215 mg/L as CaCO3) conditions. For risk assessment, the worst case value of 76.9 mg chromium trinitrate/L as EC50 is taken forward. The other short-term toxicity studies for chromium trichloride was performed using American oysters, a saltwater species and in this study a 48h-LC50 of 10.3 mg Cr/L (equivalent to 47.1 mg/L chromium trinitrate when adjusted to molecular weight) to American oyster ( Crassostrea virginica ) was reported.

Additional information
Two short-term toxicity studies for aquatic invertebrates are available, one key study on chromium trinitrate and one supportive studies with chromium(III) chloride in marine organisms (American oysters).
A daphnia short-term toxicity test was conducted by chapman et al in 1980 to evaluate the acute toxicity of chromium trinitrate und varying water hardness conditions. 48h EC50 ranged from 16.8 to 58.7 mg Cr/L (equivalent to 76.9 - 268.6 mg chromium trinitrate/L) when water hardness ranged from 52 to 215 mg/L as CaCO3. Although the original reference was not available, the result was abstracted from Ambient water quality criteria for chromium-1984, which was published by United States Environmental Protection Agency. Thus, the data can be assigned as the reliable with restrictions data. As the recommended test organism and target test substance, it gives the most weight in the three studies.
The other short-term toxicity studies for chromium trichloride was performed using American oysters, a saltwater species and in this study a 48h-LC50 of 10.3 mg Cr/L (equivalent to 47.1 mg/L chromium trinitrate when adjusted to molecular weight) to American oyster ( Crassostrea virginica ) was reported.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
