Description of key information

Short-term toxicity to aquatic invertebrates: Weight of evidence: experimental results with the substance sodium trichloroacetate and read-across from trichloroacetic acid. 
A study with sodium trichloroacetate shows a 24-h EC50 greater than 10000 mg/L.
The EC50 of trichloroacetic acid was higher than 100 mg/L for Daphnia magna based on results from several independent sources.

Key value for chemical safety assessment

Fresh water invertebrates

Additional information

Short-term toxicity to aquatic invertebrates: Weight of evidence: experimental results with the substance sodium trichloroacetate and read-across from trichloroacetic acid.

A study with sodium trichloroacetate shows a 24 -h EC50 greater than 10000 mg/L.

The EC50 of trichloroacetic acid was higher than 100 mg/L for Daphnia magna based on results from several independent sources.

Read-across:

Based on published experimental data on the analogue trichloroacetic acid and the molecular weights, the read-across approach is applied and the EC50 values for sodium trichloroacetate are calculated to be greater than 100 mg/l.
