The Purpose Of This Study Was To Determine Aldicarb, Aldicarb Sulfone, Carbaryl, Carbofuran, 3-Hydroxycarbofuran And Methomyl In Surface Water. Water Samples Were Taken For The Period From October 2003 To March 2004 To Describe And Compare The Occurrence And Distribution Of Pesticides In Agricultural Area. Water Samples Were Most Frequently Contaminated By Carbofuran And 3-Hidroxycarbofuran Compounds, Carbaryl, Methomyl , Aldicarb And Aldicarb Sulfone, Although In Low (0.1 ?gl-1) Concentrations. However, The January Through March Samples Exhibited Of All Pesticides And Metabolites, With Concentrations To 0.10 To 120.00 Ngl-1. These Results Underscore The Need To Improved Environmental Protection Measures.
