Description of key information
The adsorption/desorption study was performed in year 1996 according to OECD Guideline 106 (batch equilibrium method) and GLP.
The test substance adsorbed onto the Spodosol, Alfisol and Entisol soils with mean adsorption weight/weight percent values of 21.4, 27.4, and 22.4 %, respectively. Therefore, the test substance adsorbed in sufficient quantity to require the desorption test. The mean desorption weight/weight percent values were 16.9, -1.43, and 7.88 %, respectively.
Furthermore, the log Koc was calculated using the EIPSUITE-software. The resulting Koc was 30.71.
Key value for chemical safety assessment
- Koc at 20 °C:
- 58.8
Additional information
K'oc mean value for Soil I (Spodosol): 58.8
K'oc mean value for Soil II (Alfisol): 71.3
K'oc mean value for Soil III (Entisol): 122.7
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
