- Remarks on result:
- other: no further details reported
- Type:
- log Koc
- Value:
- ca. 2.21 dimensionless
- Remarks on result:
- other: no further details reported
- Validity criteria fulfilled:
- not applicable
- Conclusions:
- The log Koc (Koc) value of 2-chlorobenzonitrile was calculated to be 2.21 (162).
- Executive summary:
The Koc value was estimated using PKOC v1.66. The log Koc (Koc) of 2-chlorobenzonitrile was calculated to be 2.21 (162) (US EPA 2004). Experimental results are not available.
2-chlorobenzonitrile has only a low adsorption potential to soil.
Adsorption to aerosols is not expected. 2-chlorobenzonitrile has a vapour pressure of 6 Pa at 20 °C (see IUCLID section 4.6). With an average load of aerosols in the atmosphere (according to TGD, EU 2003, the specific aerosol surface is 5.6 * 10^-6 cm²/cm³), less than 0.1 % of 2-chlorobenzonitrile is adsorbed to aerosol particles.
