Administrative data
Link to relevant study record(s)
- Endpoint:
- adsorption / desorption: screening
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2009
- Reliability:
- 1 (reliable without restriction)
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 121 (Estimation of the Adsorption Coefficient (Koc) on Soil and on Sewage Sludge using High Performance Liquid Chromatography (HPLC))
- Deviations:
- no
- GLP compliance:

- Type of method:
- HPLC estimation method
- Media:
- soil/sewage sludge
- Test temperature:
- 19.4 - 19.5°C
- Type:
- Koc
- Value:
- ca. 0.38 dimensionless
- Temp.:
- 20 °C
- Matrix:
- Soil
- Type:
- log Koc
- Value:
- ca. -0.42 dimensionless
- Temp.:
- 20 °C
- Matrix:
- Soil
- Type:
- Koc
- Value:
- 0.28 dimensionless
- Temp.:
- 20 °C
- Matrix:
- Sewage
- Type:
- log Koc
- Value:
- -0.55 dimensionless
- Temp.:
- 20 °C
- Matrix:
- Sewage
- Validity criteria fulfilled:
- yes
- Conclusions:
- The retention time of the test item was lower than the retention time of the lowest reference item Acetanilide with log Koc soil 1.26 and log Koc sewage sludge 1.52.
Adsorption coefficients of the test item were calculated by extrapolation to be log Koc soil = -0.42 and log Koc sewage sludge = -0.55, corresponding to Koc soil = 0.38 and Koc sewage sludge = 0.28, respectively. - Executive summary:
The retention time of the test item was lower than the retention time of the lowest reference item Acetanilide with log Koc soil 1.26 and log Koc sewage sludge 1.52.
Adsorption coefficients of the test item were calculated by extrapolation to be log Koc soil = -0.42 and log Koc sewage sludge = -0.55, corresponding to Koc soil = 0.38 and Koc sewage sludge = 0.28, respectively.

- 0.38
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
