Description of key information
Soil Adsorption Coefficient i.e Koc value of 5-nitrovanillin was estimated to be in the range Koc 14.75 {Log Koc (1.1687) to Koc 45.289 (Log Koc 1.656). This indicates that 5-nitrovanillin is expected to have poor adsorption to the organic carbon fraction of the soil and rapid migration potential to groundwater in soil
Key value for chemical safety assessment
- Koc at 20 °C:
- 11.8
Additional information
The key study for the chemical safety assessment is Koc 14.75 (Log Koc 1.1687) at 25oC. At 20oC, this value is equivalent to Koc 11.8 (Log Koc 1.071)
