“…Recently, urban stormwater runoff has received increased attention as an important but often overlooked input pathway of hyphil-TrOCs to receiving water bodies. 12,[30][31][32] In the face of global water scarcity, urban stormwater is increasingly valued as a currently underused freshwater resource. [33][34][35] The capture, treatment, and recharge of stormwater runoff can augment urban water supplies and diversify urban water supply portfolios.…”

“…In tropical and subtropical regions, high rainfall can increase nonpoint pollution from urban or agricultural areas (Qin et al, 2010). You et al (2015) reported increases in the total concentrations of EPs after rainy periods in a tropical catchment in Singapore, which were attributed to leaks from sewer pipes and runoff from land surfaces.…”

“…The presence and environmental effects of regulated substances and EPs in freshwater ecosystems have been widely studied (Pal et al, 2010;Murray et al, 2010), but there is less information available concerning their presence and behavior in reservoirs and their potential effects on organisms in these systems (Petrovic et al, 2011). Recent studies have provided information on the presence of regulated pollutants and EPs in the waters of several reservoirs (Palma et al, 2010;Félix-Cañedo et al, 2013;Yan et al, 2014;Wang et al, 2015;González-González et al, 2014;Martinez and Peñuela, 2013;Xue et al, 2005;You et al, 2015;Xu et al, 2011) and other authors have provided evidence of potential effects on organisms living in reservoirs (González-González et al, 2014;Huerta et al, 2013b;Pérez et al, 2010;Palma et al, 2010), but information on the potential impacts of these substances in freshwater reservoirs remain poorly understood.…”

Reservoirs located in urban areas suffer specific pressures related to human activities. Their monitoring, management, and protection requirements differ from reservoirs situated in non-urbanized areas. The objectives of this study were: (a) to determine the concentrations of select pesticides and emerging pollutants (EPs) present in an urban reservoir; (b) to describe their possible spatial distributions; and (c) to quantify the risks for aquatic life and safeguard drinking water supplies. For this purpose, the Guarapiranga reservoir was studied as an example of a multi-stressed urban reservoir in a tropical region. A total of 31 organic compounds (including pesticides, illicit drugs, pharmaceuticals, and endocrine disruptors) were analyzed twice over a period of one year, together with classical indicators of water quality. The physical and chemical data were treated using principal component analysis (PCA) to identify possible temporal or spatial patterns. Risk assessment was performed for biota and drinking water use, comparing maximum environmental concentrations (MECs) with the predicted no-effect concentrations (PNECs) or drinking water quality criteria (DWC), respectively. The results demonstrated the presence of pesticides and EPs, as well as pollution by high levels of nutrients and Chlorophyll a (Chl. a), during the study period. The nutrients and Trophic State Index (TSI) showed gradients in the reservoir and regional distributions, while the pesticides and EPs only clearly showed this pattern in the dry season. The concentrations and distributions of the pesticides and EPs therefore showed seasonality. These findings suggested that the two groups of pollutants (EPs+pesticides and nutrients) possessed different sources and behavior and were not always correlated in the reservoir studied. In the studied period, no risk was observed in raw water for drinking water use, but carbendazim, imidacloprid, and BPA showed risks for the biota in the reservoir.

“…One of the main problems with the use of these compounds is that they are not fully selective and thus can cause toxic effects in non‐target organisms, representing a threat to terrestrial and aquatic ecosystems’ normal functioning . To protect human and environmental health from the chemical pollution in the aquatic environment, it is necessary to have precise knowledge about the pollutant and to understand the mechanism by which a chemical can impact an ecosystem health and water quality . Although widely detected in the environment, most of the micropollutants are poorly inventoried and regulated without or insufficient information related to their impact on surface water, groundwater and drinking water.…”

This paper is dedicated to Prof. Paola Gramatica on the occasion of her retirement.Abstract: The increase of chemical pollutants detected in different aquatic environments over the past few years has been in the focus of several studies related to their occurrence, transport, fate, and hazards, or risks to human and environmental health. In Brazil, recent studies have been conducted on the occurrence of a series of organic micropollutants (OMPs) in aquatic environments. Nevertheless, the toxicological information and environmental behavior for most of these pollutants are still difficult to evaluate. We obtained consensus models using a combina-tion of VolSurf and Dragon descriptors and Random Forest approach to predict the toxicity against Daphnia magna and Pimephales promelas for compounds identified in different sources of water in Brazil. The models showed satisfactory performance when compared with other approaches, such as Toxicity Estimation Software Tool (T.E.S.T.), etc. Both models can be used as complementary tools to aid in the prediction of organic compounds against both organisms.
