title: Pesticide sorption on geologic material of varying organic carbon content.
abstract: Sorption of three pesticides on geologic material ranging in organic carbon content from 0.33 to 6.9 g kg-1 was measured in soil columns using a miscible displacement technique. An octanol-water partitioning model was shown to be inappropriate for predicting sorption of the less hydrophobic pesticides on the low organic carbon materials.
