“…This innovation in using sewage surveillance to understand drug and pharmaceutical consumption patterns held promise for public health management and as a strategic basis for urban environmental policies. For example, in several developing countries, such as Brazil ( Barcellos et al, 2019 ), well-structured systems to identify, quantify and report pharmaceutical consumption do not exist or are highly precarious. In these countries with high social inequality, the WBE can reveal essential information from the consumption profile of the socially excluded population, which is outside the prescription pharmaceutical controls based on access to health services.…”

“…As the concentrations of pharmaceuticals reported in Brazilian surface waters have been relatively high, and certain pollutants have also been found in the water supply in significant concentrations (Dias 2014; Böger et al 2015; Lima et al 2017; Reis et al 2019), there is a need to prioritize pharmaceutical substances for monitoring and intervention. Efforts to establish a comprehensive prioritization of pharmaceuticals in Brazil and developing countries are still incipient (Barcellos et al 2019b).…”

The search for common agreement between stakeholders is one of the biggest challenges when solving environmental problems. There are different views, perceptions, knowledge, and sectoral goals for these stakeholders. In complex environmental problems, such as the management of pharmaceutical micropollutants, it is essential to establish the intersectoral and individual sector priorities for a collective approach to the problem. This research aimed to identify the priority micropollutants for intervention initiatives and the management goals of the stakeholders involved in the "product chain" of pharmaceuticals in the region of Curitiba, Brazil. First, the most consumed pharmaceutical micropollutants in the region and those previously detected in water were identified, and a "long list" of 40 pharmaceuticals was drawn up for stakeholder prioritization. Stakeholders of the region were selected by intentional sampling and were invited to a workshop that was designed to list, by consensus, the priority micropollutants and objectives for their management. The event was attended by 37 stakeholders from different sectors. It was divided into 2 stages: the 1 st stage was a multisectoral discussion to select the priority pharmaceutical micropollutants; the 2 nd stage was a sectoral discussion to establish management objectives to control and reduce the presence of these pollutants in waters. The meeting generated a coherent prioritization of pharmaceuticals where ethinyl estradiol, ciprofloxacin, ibuprofen, diclofenac, estradiol, caffeine, and fluoxetine were prioritized and their importance was justified. The main sectoral goals prioritized were related to the drug take-back program, the characterization of the presence of pharmaceuticals in the sanitation cycle, and the creation of a permanent multisector discussion environment for the theme. The multisectoral definition, established by consensus, of management priorities is promising and this strategic approach can be replicated in other developing countries.

The degradation of water resources available for human consumption is increasing with the continuous release of chemicals into aquatic environments and their inefficient removal in wastewater treatment. Several watersheds in Brazil, such as the Iguaçu River, are impacted by multiple sources of pollution and lack information about their pollution status. The Iguaçu River Basin has great socioeconomic and environmental relevance both for the supply of water resources and its high hydroelectric potential, as well as for the high rate of endemism of its ichthyofauna. Also, it is home to large conservation units, such as the Iguaçu National Park, recognized by Unesco as a Natural Heritage of Humanity. Thus, the current review discusses the chemical pollution in the Iguaçu River Basin (IRB) approaching: i) the main sources of pollution; ii) the occurrence of inorganic and organic micropollutants; iii) the available ecotoxicological data, and iv) the socioeconomic impacts in three regions of the upper, middle, and lower IRB. Different studies reported relevant levels of emerging contaminants, persistent organic pollutants (POPs), toxic metals, and polycyclic aromatic hydrocarbons (PAHs), detected in the water and sediment samples, especially in the upper IRB region, associated with domestic and industrial effluents. Additionally, significant concentrations of pesticides and toxic metals were also detected in the lower IRB, revealing that agricultural practices are also relevant sources of chemicals for this watershed. More recently, studies indicated an association between fish pathologies and the detection of micropollutants in the water and sediments from IRB. The identification of the main sources of pollutants, associated with the distribution of hazardous chemicals in the IRB and their potential effects on the biota, as described in this review, represents an important strategy to support water management by public authorities for reducing potential risks of the local endemic biodiversity and exposed human populations.
