Test material
- Reference substance name:
- 86411-30-3
- IUPAC Name:
- 86411-30-3
- Details on test material:
- C10-13 LAS (CAS #68411-30-3) with the following alkyl chain
length distribution: C11 45%, C12 36.5%, C13 18.5%. Average
chain length was 11.7 and molecular weight was 344.
Constituent 1
- Radiolabelling:
- yes
Sampling and analysis
- Details on sampling:
- Water samples were removed periodically for radiometric analysis
of 14C-labeled LAS. Four fish were removed on each of days 1, 2,
3, 5, 7, 9, 11 and 14 for radiometric analysis.
Test organisms
- Test organisms (species):
- Lepomis macrochirus
- Details on test organisms:
- Bluegill sunfish (avg wt. 4.0 g; avg length 68 mm) were placed in a
60 liter aquarium (375 fish total) and maintained for 21 days. A
second aquarium held 100 control fish. Fish were fed daily with a
dry pelleted trout chow ration of approximately 2% of body weight.
Study design

- Remarks on result:
- other: BCF104
Applicant's summary and conclusion
- Conclusions:
- The whole body BCF was measured as 104
- Executive summary:
The bioconcentration of CASRN 68411 -30 -3, a structural analog of the target substance was measured in a flow-through study on Lepomis macrochirus. The study was carried out for 21 days at 17 +/- 1 C, and included an elimination phase. The test substance was C14 -labeled LAS. The whole-bosy BCF was determined to be 104. Basde on the result, the TS is also not expected to be bioaccumulative.
