A pot experiment was conducted to study the effect of an anionic surfactant linear alkylbenzene sulfonate (LAS) application on cadmium (Cd) fractions in soils and Cd distribution in different tissues of soybean (Glycine max)plants as well as soil pH. Soil samples were treated with three levels of Cd (0, 5, and 10 mg kg-1) and five levels of LAS (0, 5, 15, 50, and 100 mg L-1). Results indicated that compared to the control soils (no Cd and no LAS treatment), soil pH increased and available Cd decreased in the soil treated with external Cd and wa...
