In order to evaluate the ability of natural organic materials to sorb organic pollutants, it is useful to define an organic carbon normalized sorption coefficient ... 

Organic carbon normalized sorption coefficients (Koc or Kom) have been correlated with a variety of physical/chemical properties and/or structural descriptors often related to the hydrophobidty of the chemical. Many of the reported methods for estimating Koc are based...
