Results and discussion
Effect concentrations
- Duration:
- 28 d
- Dose descriptor:
- EC10
- Effect conc.:
- 205 mg/kg soil dw
- Nominal / measured:
- nominal
- Basis for effect:
- reproduction
- Details on results:
- Reproduction was not significantly affected, but an indicative EC10 was estimated at 205 mg/kg soil.
Applicant's summary and conclusion
- Conclusions:
- The EC10 for Folsomia candida based on reproduction was 205 mg/kg soil.
- Executive summary:
Groups of F. candida were exposed to concentrations of 25-300 mg LABS Na/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.
