Soil Substitutes for Adsorption Measurement of Chemicals to Soil

Chemicals disposed from industrial and other uses are distributed in the environment into compartments of the atmosphere, hydroshere, lithosphere and biota. Fate of chemicals, that is, the distribution of chemicals to each compartment can be estimated from physical-chemical properties of chemicals, such as water solubility, partition coefficient(n-octanol/water), adsorption to soil and so on. Among these properties, adsorption of chemicals to soil has not been much investigated in comparison with other properties. This must be due to the tedious procedures of the measurement of adsorption of chemicals to soil. Also there is another reason that the difficulty of obtaining the soil which can represent as a sample of general soil.
