  • Title: Occurrence and downslope mobilization of quaternary herbicide residues in vineyard-devoted soils.
    Author: Pateiro-Moure M, Arias-Estévez M, López-Periago E, Martínez-Carballo E, Simal-Gándara J.
    Journal: Bull Environ Contam Toxicol; 2008 May; 80(5):407-11. PubMed ID: 18389162.
    Abstract:
    The aim of this study was to examine the fate of quaternary herbicides in soil deposits derived from erosion of vineyard-devoted soils. Herbicide occurrence in the crop soils was due to the farmer application inputs. Special attention should be paid to the presence of paraquat (PQ) in the studied vineyard-devoted soils. The major factor governing the sorption of PQ was the solid state organic fraction with the clay mineral content also making a significant contribution. The mobilization and transport of quats-enriched soil particles may generate downslope and downstream environmental problems that mainly affect detritivore ecology.
