Description of key information

Additional information

Studies on the acute toxicity of the substance are available for fish and algae. The acute toxicity data for aquatic invertebrates refer to results obtained for glyoxal a stuctural analogue of pyruvaldehyde.

The most sensitive organism in acute toxicity testing was Daphnia magna with an EC50 of 404 mg/l based on the nominal test substance concentration. In a test on Scenedesmus subspicatus an EC50 of 731.5 mg/l was the recorded. The LC50 determined in a study on Leuciscus idus was ca. 1000 mg/l.

The PNEC calculations are based on the results of the acute toxicity test performed with D. magna. The equilibrium partitioning method was used for calculating the PNECsediment freshwater/marine and the PNECsoil.

The PNEC STP was calculated using the EC10 of 6.7 mg/l determined in a growth inhibition test with the bacteria species Pseudomonas putida.
