Comparison of extraction efficiencies for water-transportable phenols from different land uses

WBM recovered with SPE correlated with water total organic carbon (TOC) content. SPE followed by THM was shown to be the approach for isolating and quantifying water-transportable phenols. All the different land uses exported similar amounts of lignin per unit weight of OC to the drainage water. We also conclude that a significant proportion of lignin phenols is lost from soils as a component of WBM in a particulate form, so the magnitude of total phenol loss is likely greater than previously thought.
