| Sumario: | The main objective of this research was to characterize the situation of water pollution by micropollutants and its current management context in the Belém River basin in Curitiba, emphasizing the residues of pharmaceuticals. For this, a literature review was conducted to identify which classes of micropollutants have been monitored in this basin and which were the concentration ranges found. Thirty-two semi-structured interviews were also conducted with stakeholders who interface with the reduction and control of pharmaceutical residues or who are linked to the management of the Belém River waters. Quantified micropollutant concentrations in this basin reveal levels of endocrine disruptors far above the limits considered safe by European toxicologists, which indicates the need to reduce and control these pollutants. Nevertheless, stakeholders interviewed point out that micropollutants (pesticides, metals and pharmaceuticals) are the priority aquatic pollutants for urban water management, to the detriment of pathogens and nutrients. Priorities for pharmaceutical residues, according to respondents, mirrored precisely the focus of European and USA studies and management initiatives that have prioritized antibiotics and hormones. However, despite the prioritization of micropollutants, management initiatives aimed at reducing and controlling them in the Belém River basin are scarce. The highlights were: the Water Purification Program of the Environment Department of Curitiba; collaborative projects between institutions (notably universities and the sanitation company); and unused or expired drug take-back. |
