Distribution Of Environmental Compartments Of Herbicides Used In The Cotton, Coffee And Citrus Cultures [distribuição Nos Compartimentos Ambientais Dos Herbicidas Utiilizados Nas Culturas De Algodão, Café E Citros]

Abstract

The aim of this paper was to evaluate the environmental fate of herbicides (acetochlor, 2,4-D, diuron, clomazone, thidiazuron, paraquat, simazine, fluazifo-p-butil, clethodim, oxufluorfen, flumioxazin, carfentrazone-ethyl, ametrina, trifluralin and MSMA) in cotton, coffee and citrus cultivation areas, applying the level I fugacity model. The methodology basically used the chemical and physical characteristics of the pesticides, environmental compartments and the fugacity equations. The preliminary evaluation of risk of contamination due to the use of these pesticides on the cultures studied was carried out swiftly, based on the chemical and physical properties of these products as the level I fugacity model was applied. For most of the herbicides evaluated, the water compartment was the most vulnerable. The prediction evaluation study using fugacity level I was found to be a relevant tool for the environmental fate of the herbicides studied for cotton, coffee and citrus cultures.271123132Bru, R., Carrasco, J.M., Paraíba, L.C., Unsteady state fugacity model by a dynamic control system (1998) Appl.
