Key value for chemical safety assessment

EC50 for freshwater algae:
500 mg/L

Additional information

In a non-GLP, 72-hour static test with the green alga Scenedesmus subspicatus (new name: Desmodesmus subspicatus) similiar to German Industrial Standard DIN 38412 part 9, the algae toxicity of thiodiglycol was investigated. Statistical evaluation of the endpoint growth rate revealed an EC50 (72h) >500 mg/l, related to the nominal concentration.
