Description of key information
Additional information
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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
