摘要：

Direct measurements of adsorption coefficients of Cd‐ions on soils were compared with adsorption coefficients derived from migration experiments in soil columns; reasonable agreement exists between the two sets of data. With the help of the adsorption coefficients, data from the literature on the uptake of Cd by plants and a mathematical model, the future accumulation of Cd was calculated for different types of soil to which Cd via sewage sludge will be applied. Cd‐content of plants was also calculated. From the results it follows that if recently proposed Cd‐application limits are adhered to these soils, accumulation will be prevented for a long time.
