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 ECof the test material to be ≥1 mg/l where the EC₅₀ is above the limits of solubility.
