Distribution
For the adsorption of dimethyl sulphate in a soil-water system a log Koc of 1.38 is calculated according to the TGD (EC 1996). From this it can be concluded that DMS has a low adsorption potential and thus a high mobility/leaching potential. For the volatility of DMS from water to air a Henry constant of 0.39 Pa.m3/mol is calculated at a temperature of 25°C and a vapour pressure of 87 Pa. This means that the compound shows no tendency to evaporate from water.
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.
