Toxicity to terrestrial plants
Administrative data
- Endpoint:
- toxicity to terrestrial plants: short-term
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Well-documented study.
- Justification for type of information:
- Category Approach; test material is reference substance LAS. LAS provides suitable read across for LAB Sulfonic Acids as both form the identical chemical species in aqueous solutions at neutral (environmental) pH, namely, the LAS ion (C10-13 linear alkyl benzene-SO3-) and would be expected to have similar ecotoxicological properties.

Materials and methods
Test guideline
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- Three species of crop plant B. rapa, A. sativa, and S. alba, were grown in soil containing concentrations of LAS that varied from 0 -10,000 mg/kg dw soil. The seedlings were grown for 14 days, and then weighed. The weight was compared to weights of controls plants.

Applicant's summary and conclusion
- Conclusions:
- The EC10 for B. rapa was 86 mg/kg dw soil, for A. sativa it was 80 mg/kg dw soil, and for S. alba it was 200 mg/kg soil.
- Executive summary:
Three species of crop plant B. rapa, A. sativa, and S. alba, were grown in soil containing concentrations of LAS that varied from 0 -10,000 mg/kg dw soil. The seedlings were grown for 14 days, and then weighed. The weight was compared to weights of controls plants. All three species showed a dose-related reduction in growth. The EC10 for B. rapa was 86 mg/kg dw soil, for A. sativa it was 80 mg/kg dw soil, and for S. alba it was 200 mg/kg dw soil.
