Applicant's summary and conclusion
- Conclusions:
- Groups of 10 male and 10 female Folsomia fimetaria were exposed to various concentrations of Na-LAS in three different soil types for 21 days. At the end of this period, the number of adult and juvenile organisms was counted. Another test was done to compare the toxicity of three LAS salts, Na, Ca, and Mg, in one soil type (sandy). There was little variation in toxicity among the three soil types and in the three salt species. The EC10 for Folsomia fimetaria in various soils ranged from 85-93 mg/kg dry weight soil. The EC10 for Folsomia fimetaria in various soils ranged from 85-93 mg/kg dry weight soil.
