Enantioselective sorption of the chiral fungicide metalaxyl on soil from non-racemic aqueous solutions: Environmental implications

•Sorption of metalaxyl enantiomers on soil from non-racemic solutions was determined.•Total (R+S)-metalaxyl sorption increased for solutions enriched with R-enantiomer.•The more abundant R-metalaxyl enantiomer was preferentially sorbed by the soil.•Sorption enantioselectivity was proposed to be caused by sorbate–sorbate interactions.•Important environmental implications are discussed.
