Sorption and degradation of four nitroaromatic herbicides in mono and multi-solute saturated/unsaturated soil batch systems

摘要

This paper presents a study on sorption and degradation processes involved in the fate of nitroaromatic herbicides in an alluvial sandy loam. Particular attention was given to a competitive sorption process and its impact on herbicide biodegradation through bioavailability modification. The main question addressed was the occurrence of antagonistic or synergistic effects in herbicide Mixtures. Approaching the problem by using a herbicide combination, it was demonstrated that the More soluble herbicides strongly decreased the sorption of the more hydrophobic ones on the soil Organic fraction.
