Description of key information
In a GLP-study similar to OECD Guideline 106 (Adsorption - Desorption Using a Batch Equilibrium Method) and also to EPA N 163 -1 using four soils, the absorption coefficient of one of the two constituents of the registered substance was determined to be in the range of 351 to 630 (geometric mean: 514.98) with desorption coefficients between 526 and 934 ml/g (depending on the soil). This result is considered for the registered substance.
Key value for chemical safety assessment
- Koc at 20 °C:
- 527.3
Additional information
The adsorption and desorption of one of the two constituents of the registered substance was determined in four soils namely a sandy loam (Soil I, California Porterville), a loamy sand (Soil II, Illinois 1A), a silt loam (Soil III, Illinois, Site 1) and a loam (Soil IV, Iowa 1A) using radio-labelling.
The total recoveries obtained for the highest concentrations were in a range of 98.6% and 103.2% of the radioactivity applied.
The mean of the four respective Koc was calculated to be 527.3.
This result is considered for the registered substance.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
