This study concerned the influence of a mineral oil adjuvant used as tank-mix, on the sorption of commercially formulated compounds in soil using a laboratory-scale sediment/water system. The laboratory experiment was conducted with the adjuvant Atpolan 80 EC and the triazine herbicide atrazine and isoxaflutole which belong to the isoxazole class of herbicides. Ditch bed sediment was the medium. Pesticide distribution was measured in the aqueous phase, both in systems with and without the sediment. The proportion of pesticide moving into the sediment layer was depended on physicochemical properties of the compounds, but it was also influenced by the adjuvant in case of atrazine and only slightly in that of isoxaflutole. Atpolan 80 EC also caused an increase of Kd and Koc values of atrazine.
