Short-term toxicity to fish
Administrative data
- Endpoint:
- short-term toxicity to fish
- Type of information:
- migrated information: read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- supporting study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- Because of the shorter than normal study duration and smaller than standard number of fish per concentration, the reliability of the absolute values cannot be assessed. However, the study is considered reliable for the trends in the data because the homologues were tested under identical conditions.

Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- other: EPA-660/3-75-009 1975. Method for acute toxicity tests with fish, macroinvertebrates and amphibians.
- Principles of method if other than guideline:
- Acute toxicity tests were conducted on high molecular weight LAS, individual pure homologues, non-linear LAS components (dialkyl tetralin or indane sulfonates, DTIS), and model biodegradation intermediates (sulfophenylundecane, SOU) in order to determine whether biodegradation decreases toxicity. Toxicity tests were conducted in 5 L of 100 mg/L hardness water using 5 fathead minnows per concentration.
