Abstract: Laboratory measurements of the retention of 10 phenoxyacetic pesticides in soil amended with progressive concentrations of humic acid (HA) ranging from 1 to 10(4) mg kg-1, showed sorption patterns depending on the pesticide structure and form (acid or ester). Some results point to competitive effects between pesticide and HA in the presence of the soil mineral matrix, partly accounting for a negative effect of low HA addition rates ( 100 mg kg-1) in the sorption of phenoxyacetics, mainly in acid forms.
