Applicant's summary and conclusion

Conclusions:
Groups of F. candida were exposed to concentrations of 25-300 mg LAS/kg soil. Exposure lasted 28 days, after which adult survival and reproductive parameters were examined. The EC10 based on reproduction was 205 mg/kg soil. The EC10 for Folsomia candida based on reproduction was 205 mg/kg soil.
