- Transformation products:
- not measured
- Details on results (Batch equilibrium method):
- The study was conducted according to OECD Guideline 106 with some modifications. The soil sorption coefficient log Koc of acetophenone was determined to 0.9728 (Koc=9.4).
Any other information on results incl. tables
The study was conducted according to OECD Guideline 106 with some modifications. The soil sorption coefficient log Koc of acetophenone was determined to 0.9728 (Koc=9.4). In respect to acetophenone the linear sorption equation (Cs=Kd x Ce; Cs=sorbed concentration on soil of the chemical at equilibrium (mg/kg), Kd=soil sorption coefficient (dependent on soil texture, eg. organic carbon), Ce=equilibrium concentration in solution (mg/L)) is more desirable than the Freundlich equation to fit the data of sorption experiments because the n values calculated by Freundlich equation were much greater than 1.2, suggesting nonideality.
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Conclusions:
- Based on the results, binding of acetophenone to soil organic matter is to be expected to be very low (Koc=9.4; log Koc=0.9728)
- Executive summary:
The study was conducted according to OECD Guideline 106 with some modifications. The soil sorption coefficient log Koc of acetophenone was determined to 0.9728 (Koc=9.4). In respect to acetophenone the linear sorption equation (Cs=Kd x Ce; Cs=sorbed concentration on soil of the chemical at equilibrium (mg/kg), Kd=soil sorption coefficient (dependent on soil texture, eg.g. organic carbon), Ce=equilibrium concentration in solution (mg/L)) is more desirable than the Freundlich equation to fit the data of sorption experiments because the n values calculated by Freundlich equation were much greater than 1.2, suggesting nonideality.
Based on the results, binding of acetophenone to soil organic matter is to be expected to be very low. The study is regarded as valid.
