- Abstract
Brazil, a country with a strong agricultural sector and holder of 12% of the planet's freshwater, has stood out worldwide in terms of pesticide consumption. These substances are among the main agricultural effluents, representing a risk to aquatic ecosystems. Ordinance No. 888 of 2021 of the Ministry of Health provides for the mandatory monitoring of pesticides in the water supplied to the Brazilian population, however, a small number of municipalities comply with the determination. In this sense, this study aims to propose a method for prioritizing crops, active ingredients, and times for monitoring pesticides in water sources. Data on the planted area with crops, their phenology, and plant health were used; the sale of pesticides and their physical and chemical parameters; and the climatic conditions of the state to propose the method. Coffee, sugarcane, corn, and banana were indicated as priority crops in the state of Espírito Santo. Of the 86 pesticides sold in the state, 54 were considered a priority for monitoring due to characteristics related to greater exposure, such as use, commercialization, favorable environmental dynamics, mostly during the rainy season of the year. There are statistically significant differences between the concentrations of pesticides found in the water in the priority and non-priority months, confirming the effectiveness of the method for setting priorities in pesticide monitoring. Thus, it is important to highlight the potential of the method to help states, municipalities, and regions to select, prioritize and monitor pesticides in their sources in a more assertive and adapted to local singularities.
