- Endpoint:
- toxicity to soil macroorganisms except arthropods: long-term
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because direct and indirect exposure of the soil compartment is unlikely

Description of key information
No terrestrial toxicity data are reported for sodium cumenesulphonate. Given the low potential for sodium cumenesulphonate reaching the terrestrial compartments (EQC modelling results), the lack of persistence (ready biodegradability under aerobic conditions) or bioaccumulation (BCFWIN modelling results), and the low likelihood of the chemicalpartitioning to soil and sediments (EQC modelling results), the lack of ecotoxicity data is not considered a deficiency.
The ECOSAR QSAR model predicts that 14-day, LC50 (14-day, earthworm) would to be 890.327 mg/L (ppm).
1 kg of water has a volume of 1 L and the mg/kg and mg/L are the same.
LC50 (14-day, earthworm)= 890.327 mg/kg soil dw
Key value for chemical safety assessment
- Short-term EC50 or LC50 for soil macroorganisms:
- 890.327 mg/kg soil dw
- Long-term EC10, LC10 or NOEC for soil macroorganisms:
- 178.07 mg/kg soil dw
