- Remarks on result:
- other: E. crypticus
- Details on results:
- No toxicity to E. crypticus was seen at any dose level, including the highest dose level of 120 mg/kg soil. A dose-related inhibition of cocoon production was seen in A. caliginosa at the highest concentration of 150 mg/kg soil.
Applicant's summary and conclusion
- Conclusions:
- Groups of A. caliginosa were exposed to soil containing 25 -150 mg/kg soil of LAS for 28 days. Groups of E. crypticus were exposed to concentrations of 0, 10, 40, 60, 80, 100, or 120 mg/kg soil (nominal). EC10 values based on reproduction were 46 mg/kg soil for A. caliginosa, and >= 120 mg/kg soil for E. crypticus.
