“…At the Bananal Branch, it is believed that atrazine loads may be influenced by both point and diffuse sources. Wittmer et al 35 shows that the presence of agricultural loads in urban WWTPs may be a consequence of single disposal activities, since atrazine was also found in WWTP samples. Benotti et al 36 detected atrazine in waters far from agricultural activities where wastewater was the only known source of contamination.…”

Selected emerging contaminants in water samples from the Brazilian capital were investigated by liquid chromatography-mass spectrometry after solid-phase extraction. In Paranoá Lake, an urban reservoir that will be used to produce drinking water, caffeine was the most abundant contaminant found (average of 53 ng L ). The role of wastewaters discharges could not be evidenced probably due to the water flow and circulation in the lake. However, higher concentrations were detected during the dry season suggesting the presence of point sources, except for atrazine. In source waters, concentrations were lower in comparison with Paranoá Lake waters. Environmental risk assessment shows the need for further surveys for atrazine. For drinking waters, only caffeine and atrazine were detected at average concentrations of 8.6 and 3.2 ng L -1 , respectively. No risk for human health was observed.

“…However, pesticides and biocides can be also used in urban areas for gardening and other non-crop protection purposes. Due to the input of urban run-off into the sewer lines, the presence of pesticides in urban wastewaters should not be underestimated: some studies have found that urban biocides loads can be found in water in the same range as the most widely-used agricultural pesticides [9][10][11]. Therefore, evaluation of WWTPs performance regarding elimination of micropollutants such as pharmaceutical products and pesticides is necessary to assess their potential impact in the environment.…”

Water reuse is becoming a common practice in several areas in the world, particularly in those impacted by water scarcity driven by climate change and/or by rising human demand. Since conventional wastewater treatment plants (WWTPs) are not able to efficiently remove many organic contaminants and pathogens, more advanced water treatment processes should be applied to WWTP effluents for water reclamation purposes. In this work, a pilot plant based on microfiltration (MF) followed by reverse osmosis (RO) filtration was applied to the effluents of an urban WWTP. Both the WWTP and the pilot plant were investigated with regards to the removal of a group of relevant contaminants widely spread in the environment: 28 pharmaceuticals and 20 pesticides.The combined treatment by the MF-RO system was able to quantitatively remove the target micropollutants present in the WWTP effluents to values either in the low ng/L range or below limits of quantification. Monitoring of water quality of reclaimed water and water reclamation sources is equally necessary to design the most adequate treatment procedures aimed to water reuse for different needs.

“…The herbicides or fungicides currently used in aquaculture were originally developed for use in agriculture or as additives for boat anti-fouling paints 26 . Accordingly, many studies have investigated and demonstrated the presence of pesticides and biocides in surface waters [27][28][29][30][31] .…”
