SUMMARY:

The aim of this thesis was to analyze situations about the contamination of surface freshwater by pesticides from the global, national and regional perspectives. Global contamination and ecotoxicity datas were obtained from published articles and ecotoxicological databases. Contamination data at the regional level were obtained from a field study with four sampling collections, in dry and rainy seasons, conducted in the main agricultural basin of the Federal District, Brazil. The results showed that atrazine was the most detected pesticide on a global and regional scale and indicate the wide use of this molecule, as well as its persistence in the environment. However, other pesticides even at low concentrations can cause toxic effects to aquatic biota for this deserve attention. Regarding the Brazilian regulations, the study showed that of the 27 pesticides with the limits established, 17 needs of update since the current values do not protect the aquatic organisms. Thus, this thesis contributed to filling gaps on pesticides in surface freshwater and on the management of water bodies in relation to these contaminants.
