Description of key information

Calculation with ECOSAR v1.00 (EPIWIN software by US-EPA), Chronic Value for fish: 8130 g/L 

Key value for chemical safety assessment

Additional information

The prediction for long-term toxicity for aquatic organisms of the substance 1-Propanesulfonic acid, 3-mercapto-, monosodium salt (MPS) 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 fish a Chronic Value (ChV) of 8130 g/L was predicted. However, since this value reveals only a concern of toxicity and no numerical value, it cannot be taken into account for the chemical safety assessment.
