Coefficient of pollution

Partition coefficient between octanol and air (K0A) is determined by the relationship of chemical concentrations in octanol and air (K0a = Co/CA). The K0A is directly connected with the soil-air partition coefficient of pollutant K A which is determined as the ratio of solid phase to air concentrations (Ksa = Cs/CA) or through other constants (KSA = KSw/KAw). 

In addition to the population equivalent, the term coefficient of pollution has also been introduced, which is a measure of pollution and harmfulness of industrial wastewaters and expresses how many times are the wastewaters in question more polluted and harmful than sewage waters. 

When evaluating data on the diffusion coefficients of pollutant in soils or porous mineral materials some peculiarities in the literature must be considered (Shackelford and Daniel 1991b). Under the simplified assumptions made here, the permeation rates and the permeability and the induction times of pollutant diffusion in the mineral liner are determined by the basic parameters Do, which depend on the pollutant only, by quantities 0 and Dwhich depend on the mineral liner material only and by R which depends on the pollutant and the mineral liner material as well. However, diffusion experiments provide no direct values for these basic quantities but only experimental quantities which depend on them. According to the first...
