Additional information

According to a Mackay Level I model calculation, the main target compartment for bis(4-fluorophenyl) ketone will be the hydrosphere (70 %), followed by sediment and soil (13 % each). The calculated Henry’s Law constant of 0.12 Pa m³/mol at 20 °C indicates low volatility of bis(4-fluorophenyl) ketone from surface waters. The adsorption / desorption behaviour as studied with the batch equilibrium method indicates a very low potential of 3-cyano-3,5,5-trimethylcyclohexanone for sorption to soil or sediment organic matter (Blume scale).
