PROBABILITY DISTRIBUTION OF CADMIUM PARTITIONING COEFFICIENTS OF CROPLAND SOILS

The solution to solid partitioning coefficient (Kd) is an important parameter in assessing the environmental and health risks of potentially toxic metals in soils. Ideally, the metal in solution phase should be determined at the field moisture condition under which the exposures take place. In reality, it is often represented by the concentration in extracts of a given soil-to-water ratio. Using cadmium (Cd) as an example, we demonstrated the...
