“…Some of the earliest reports of this relationship include these by Sherburne and Freed,36 Sheets,37 Upchurch,38 Harris and Warren,39 Hance40 and Lambert et al ,41 and were followed by many researchers in the late 1960s and early 1970s 1. 42–45 Hundreds of studies since have confirmed the relationship. This observation leads to the assumption that it is soil organic matter, acting as a non‐polar phase or surface, that is the main sorbent in soils, attracting pesticides because they are typically non‐polar organic molecules.…”

The soil sorption coefficient Kd and the soil organic carbon sorption coefficient KOC of pesticides are basic parameters used by environmental scientists and regulatory agencies worldwide in describing the environmental fate and behavior of pesticides. They are a measure of the strength of sorption of pesticides to soils and other geosorbent surfaces at the water/solid interface, and are thus directly related to both environmental mobility and persistence. KOC is regarded as a 'universal' parameter related to the hydrophobicity of the pesticide molecule, which applies to a given pesticide in all soils. This assumption is known to be inexact, but it is used in this way in modeling and estimating risk for pesticide leaching and runoff. In this report we examine the theory, uses, measurement or estimation, limitations and reliability of these parameters and provide some 'rules of thumb' for the use of these parameters in describing the behavior and fate of pesticides in the environment, especially in analysis by modeling.

“…Aeeordingly, the often reported eonsiderable uptake of weakly polar moleeules by the organie matter in soil (e.g. Goring, 1967;Hamaker, 1975) is eompatible with the numerous hydrophilie sites in the organie matter. The existenee of such hydrophilie sites is demonstrated by the relatively high exchange capacity of the soil organie matter und er the eonditions prevalent in most soils.…”
