Description of key information

Calculation with ECOSAR v1.00 (EPIWIN software by US-EPA): 
EC50(96h): 95923 mg/L ( 95.92 g/L)
Chronic Value for green algae: 12480 mg/L (12.48 g/L)

Key value for chemical safety assessment

Additional information

The prediction for acute and long-term toxicity for aquatic organisms of 1 -Propanesulfonic acid, 3 -mercapto-, monosodium salt was determined by the computer program ECOSAR v1.00 (EPIWIN software) by US-EPA (Chemservice S.A., 2011). The program uses an extensive set of structure-activity relationships (SARs) to estimate the toxicity of chemicals discharged to water. For green algae an EC50(96h) of 95.92 g/L and a Chronic Value (ChV) of 12.48 g/L was predicted. No GLP criteria are applicable for the usage of this tool, but due to the fact that it is a scientifically accepted calculation method the estimations performed are reliable with restrictions and can be used for the chemical safety assessment.
