Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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.
