Description of key information

Additional information

No studies on adsorption are available for substances belonging to the category C7-C9 aliphatic hydrocarbon solvents. However, category members are not expected to sorb significantly to organic matter in soil, sediment, and wastewater solids based on calculated log Koc values, with isoheptane having a log Koc of 2.30.

The distribution of the substance in the environmental compartments, air, water, soil, and sediment, has been calculated using the PETRORISK Model, version 5.2. Based on the regional scale exposure assessment, the multimedia distribution of the substance is 96% to air, 1.6% to water, 0.65% to soil and 2.1% to sediment. Distribution modeling results are included in the 'Multimedia distribution modeling results' tab in the PETRORISK spreadsheet attached to IUCLID Section 13.
