Resumo: | Contamination of water by pesticides is one of the main environmental problems. Among the agricultural crops, potatoes stand out, as they employ a large quantity of pesticides throughout their production. This article aims to present a case study on the potato processing activity, discussing the environmental licensing process of the activity and the analysis of the impacts caused by the release of effluents into the environment. The effluent was collected in a sedimentation tank of an English-type potato processing industry, sent to the Pesticide Residue Analysis Laboratory for the detection of the possible pesticides present, being analyzed by High Performance Liquid Chromatography (HPLC) and characterized physicochemically through temperature, turbidity, pH, dissolved oxygen, Electrical Conductivity, Biochemical Oxygen Demand, Chemical Oxygen Demand, Dissolved Solids, Suspended Solids, Settleable  Solids and Total Solids analyses using the Standard Methods for the Examination of the Water and Wastewater. In the HPLC analysis, the presence of 7 active pesticides was found, and the physicochemical analyses showed that turbidity and suspended solids are in disagreement with existing legislation. It can be concluded that pesticide residue analyses should be a requirement of the legislative body for the issuance of environmental licenses, only with the analyses required until now, it is not possible to measure all substances being discharged into water bodies. Furthermore, it is suggested that more restrictive limits be added to legislation regarding pesticides in surface waters.
