Description of key information
The Koc values was determined to be 351 (acidic sandy soil), 395 (loamy sand) and 183 (alkaline sandy loam) respectively. The Koc values for each of the three soils are between 100 and 1000, therefore, the test item is not expected to be strongly immobile or strongly mobile in soil.
Key value for chemical safety assessment
- Koc at 20 °C:
- 395
Additional information
A study was performed for the Determination of the Adsorption Coefficient according to OECD TG 106. The adsorption test with the test item was conducted in acidic sandy soil (SC-1), loamy sand (Roger Myron-North) and alkaline sandy loam (Mutchler) and 0.01 M CaCl2 at a 5:1 solution to soil ratio. The Koc values was determined to be 351 (acidic sandy soil), 395 (loamy sand) and 183 (alkaline sandy loam) respectively. The results indicate that the test item, adsorbed to the SC-1, Roger Myron-North and Mutchler soils. The test item adsorbed between 25 - 53% for the three soils, but did not desorb readily from any of the soils. The Koc values for each of the three soils are between 100 and 1000, therefore, the test item is not expected to be strongly immobile or strongly mobile in soil.
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.
