Description of key information

Many valid studies (key and supporting studies) are available dealing with the soil and sediment sorption of acetophenone. Various soils and sediments were tested. According to the available and reliable data obtained via guideline studies, the soil sorption coefficient Koc of acetophenone was determined to be in the range between 9 and 95. According to the classification of Blume & Ahlsdorf (1993), acetophenone can be regarded as a substance with very low to low  binding strength to organic matter of soil and sediments.
