Reference
Description of key information
The substance has a potential for adsorption to soil and suspended matter based on the log Koc of 3.5 (OECD 106)
Key value for chemical safety assessment
- Koc at 20 °C:
- 3 162.28
Additional information
The adsorption/desorption of the substance was investigated in a study
conducted according to OECD guideline 106. The tested number of soils
deviated from the guideline recommendation. Instead of five soils, the
adsorption/desorption potential was tested using three different soils.
The used standard soils were LUFA standard soil 2.2 (loamy sand), LUFA
standard soil 6S (clay) and Eurosoil 4 (silt). An initial test
concentration of 100.2 mg/L was applied to all soil types. The
adsorption was determined by analysis of substance concentration in the
water phase after 24, 48 and 72 hours. The determined Kd values
were 3.2, 8.5 and 5.6 cm³/g for LUFA standard soil 2.2 (loamy sand),
LUFA standard soil 6S (clay) and Eurosoil 4, respectively. The log Koc
values were 3.2, 3.7 and 3.6 for LUFA standard soil 2.2 (loamy sand),
LUFA standard soil 6S (clay) and Eurosoil 4, respectively. The geometric
mean log Koc for all three soil types is 3.5.
