Description of key information
Additional information
Toxicity to soil macroorganisms except arthropods:
Key study: read-across from trichloroacetic acid: Test method according to EU C8 guideline. The LC50 (14 days) of trichloroacetic acid for Eisenia fetida was 1139.9 mg/Kg soil dw. Based on the molecular weights the LC50 (14 days) for sodium trichloroacetate would be 1293 mg/Kg soil dw.
Toxicity to terrestrial arthropods:
Key study: The 48-h LD50 of sodium trichloroacetate was greater than 100 µg in bees. Test method was according to OECD guideline 213.
Toxicity to terrestrial plants:
Key studies: Read-across from trichloroacetic acid: The EC50 value (2 weeks) of trichloroacetic acid for Avena sativa in a loam sand soil culture was 4.6 mg/kg soil dw. The NOEC value was 1 mg/kg. (test method acccording to OECD guideline 208). Based on the molecular weights, the EC50 for sodium trichloroacetate would be 5.22 mg/kg soil dw.
With sodium trichloroacetate, ED50 values of 100 ± 9.1 and 12 mg/L nutrient solution were calculated from the 50% reduction of the total biomass (excluding the roots) and the seed mass, respectively (total life-cycle of the plant). Test method was according to the German guideline: Biologische Bundesanstalt, Braunschweig, Germany, March 1984.
Toxicity to birds:
Key study: The LD50 of sodium trichloroacetate was greater than 2000 mg/kg for qualis (Coturnix coturnix japonica). Test method was according to OECD guideline 223.
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.
