The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Based on the calculated and experimental Koc values (Koc=51-270), acrolein is expected to be moderately to highly mobile in soil. However, there are indications that the adsorption of acrolein to soil (bound fraction) is irreversible.

Henry’s Law constant (calculated: 6.1 Pa x m³/mol at 20°C. measured: 3.1 Pa x m³/mol at 20°C and 1.22 x 10-4atm x m³/mol at 25°C) indicates that volatilisation from surface waters and moisty soil is expected to be high.

Whilst physical removal from the atmosphere by precipitation and dissolution in clouds can occur, the short atmospheric residence time suggests that wet deposition is of limited importance.
