Additional information



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.
