Sampling and analysis
- Analytical monitoring:
- yes
- Details on sampling:
- Initial concentrations were measured.
Test substrate
- Vehicle:
- yes
- Details on preparation and application of test substrate:
- LABS Na was mixed in demineralized water, and then added to dry Askov soil. Fresh sludge (approx. 200 g) was freeze-dried. This was crushed and sieved through a 2 mm sieve. A methanol solution of LAS was then added to the sludge.

Applicant's summary and conclusion
- Conclusions:
- The EC10 for A. caliginosa was 46 mg/kg soil. The EC10 for E. crypticus was >=120 mg/kg soil.
- Executive summary:
Groups of A. caliginosa were exposed to soil containing 25 -150 mg/kg soil of LABS Na 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.
