OECD SIDS LINEAR ALKYLBENZENE SULFONATE (LAS) Species Endpoint EC10 EC50 Chenopodium album Growth 164 Amaranthus retroflexus Growth 142 Nigella arvensis Growth 132 Galinsoga parviflora Growth 90 Sorghum bicolour Growth 137 Helianthus annuus Growth 289 Phaseolus aureus Growth 316 Avena sativa Growth 50 300 Sinapis alba Growth 200 300 Test Substance: LAS (unspecified) Remarks: Values are extracted from a variety of original references and compiled for this article. NOEC values were extrapolated by applying an assessment factor of 10 to the EC50. This is considered an unreliable assumption as measured acute-to-chronic ratios for LAS in plants vary between 2 and 6. Reference: Jensen, J., Lokke, H., Holmstrup, M., Krogh, P.H. and Elsgaard, L. 2001. Effects and risk assessment of linear alkylbenzene sulfonates in agricultural soil. 5. Probabilistic risk assessment of linear alkylbenzene sulfonates in sludge-amended soils. Environmental Toxicology and Chemistry 20:1690- 1697. Reliability: 4 This study was given a reliability score of 4 because the original reports reviewed by the authors were not directly reviewed in the compilation of this robust summary. (b) Species: Grass, beans, radishes, potatoes Radiolabel: Yes Results: No adverse effects on plant biomass were observed at the concentrations tested [initial concentrations in soil = 27.2 mg/kg (grass, beans, radishes); = 16.2 mg/kg (potatoes)] Temperature: Room temperature Method: Soil cores taken from two ecosystems were collected and placed in a climate controlled “plant metabolism box”. Ecosystem Section I consisted of a heavy, clay-like soil. Radiolabeled LAS (a defined mixture) absorbed to digested sludge was incorporated into the soils, after which the soils were planted with either grass, bush beans and radishes (Section I) or potatoes (Section II). The test systems were maintained under a defined standard climate (i.e., an average day in June in Northern Germany) for the vegetative period (76 and 106 days, respectively for Sections I and II). At the end of the growing season samples were collected from plants and soil and subjected to radioanalysis. GLP: Yes [ ] No [ ] ? [X] Test Substance: LAS. The authors state that they tested a defined mixture of LAS, but do not report the composition in this paper. Reference: Figge, K. and Schoberl, P. 1989.

OECD SIDS LINEAR ALKYLBENZENE SULFONATE (LAS) GLP: Yes [ ] No [ ] ? [X] Test substance: Commercial LAS with an average carbon chain length of C11.8. Remarks: Information as cited in IUCLID Data Sheet for CAS #68411-30-3. The substance was tested in the range of 2.57 to 257 mg MBAS/kg Nominal concentrations, synthetic soil, static, pH 5.0-7.5, temperature 20-25 ºC. Results are expressed as mg MBAS per kg soil. First Observed Effect Concentration (FOEC) is 77.1 mg MBAS/kg, EC50 is about 77.1 but below 257 mg MBAS/kg. Reference: European Commission. 2000b.
