Abstract: The aim of this study was to investigate the sorption and desorption of thiamethoxam in contrasting soils under the effect of organic acids. The results showed that MTo sorption had higher Kd. The presence of organic acids increased sorption and reduced desorption of thiamethoxam at MTo. The opposite was observed for the LVdf where the presence of 400 μmol L-1 of acid reduced the sorption of thiamethoxam in a concentration of 20 μmol L -1, not influencing desorption. The dynamics of organic acids with minerals from the soil particles were clarified by infrared analysis.
