Description of key information
The short term toxicity of dipotassium heptafluorotantalate was determined in Daphnia.
According to the key study (Caspers, 2001) performed to GLP and in accordance with standardised guideline EU Method C.2, there were no signs of short term toxicity in invertebrates within the limits of solubility.
Key value for chemical safety assessment
Additional information
The key study (Caspers, 2001) is a GLP compliant study performed in accordance to the standardised guideline EU Method C.2, the equivalent of OECD 202. The study was performed to a good standard in line with sound scientific principles and was assigned a reliability score of 2, using the principles set out in Klimisch (1977). The robust study exposed Daphnia maga to a nominal concentration of ≥1 mg/l under a limit test. Under the conditions of the test no fatalities or systematic effects of toxicity were observed. The study determined the EC₀ of the test material to be ≥1 mg/l where the EC₅₀ is above the limits of solubility.
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.
