- not required
- Key result
- Sample No.:
- #1
- Type:
- Koc
- Value:
- 1.6 dimensionless
- Validity criteria fulfilled:
- yes
- Conclusions:
- The HPLC method using soil-adsorprion-reference data was applied for the determination of the adsorption coefficient (Koc) of Eversorb EP4.
- Executive summary:
The adsorption results of Eversorb EP4 have log Koc values, -0.33.
The substance with a low Koc (1.6) can be considered to have a high mobility in soil according to MCCALL classification scheme. The potential to be absorbed in soil is low.
