Description of key information

Read across to thioglycolic acid.
Acute toxicity of thioglycolic acid to Daphnia magna has been investigated through the OECD TG 202 and GLP requirements.
EC 50 - 48h determined was of 38 mg/L, based on measured concentrations.
Thioglycolic acid can be therefore considered as harmful for invertebrates.

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
38 mg/L

Additional information

Read across to thioglycolic acid.

Acute toxicity of thioglycolic acid to Daphnia magna has been investigated through the OECD Guideline 202 and GLP requirements.

Daphnia magnawere exposed for 48 hours to an aqueous solution of thioglycolic acid at different nominal concentrations of 0.20 - 0.39 - 0.78 - 1.56 - 3.13 - 6.25 - 12.5 - 25 and 50 mg/L.

15% immobilisation of the test organisms was recorded after 24h of exposure at the highest test concentration of 47 mg/L.

EC 50 - 48h determined was of 38 mg/L, based on measured concentrations.

Thioglycolic acid can be therefore considered as harmful for invertebrates.
