【 摘 要 】

This study aimed to verify the application of the LIX index as a leaching screening method for the agrotoxic metolachlor, endosulfan, chlorpyriphos, carbendazin and diuron. For this, soil samples were collected, deformed and not deformed, from an Yellow Latosol cultivated with cotton from the municipality of Primavera do Leste, MT (Brasil), in the horizons Ap ( 0-20 cm), A/B ( 20-40 cm) and Bw1 ( 40-92 cm). A leaching simulation was done in the laboratory; and sorption coefficient and soil physical-chemical attributes directly related to agrotoxic leaching, were determined. For assessment of the leaching potential it was used the LIX index. In general, the experimental results in laboratory were in agreement with the LIX index results, whereas diuron and metolachlor which have higher mobilitly in the soil columns, also presented higher LIX value. However, the classification range purposed by the LIX authors did not explain the high mobility found for metolachlor in the laboratory simulation.
