“…21 Thus, the most important pathway for DEET into aquatic environments is wastewater inputs after washing off and excretion performed by humans. 22 Finally, atrazine was found at the lowest concentrations in surface waters, between 1.2 ± 0.9 to 5.5 ± 0.4 ng L -1 . Atrazine is an herbicide from the group of triazines, widely used in crops of sugarcane and corn.…”

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.

a b s t r a c tPharmaceuticals in drinking water sources (DWSs) have raised significant concerns for their persistent input and potential human health risks. Currently, little is known about the occurrence of pharmaceuticals in DWSs in China. In this study, a survey for multi-class pharmaceuticals in DWSs of five major river watersheds in China was conducted from 2012 to 2013. Samples were collected from 25 sampling sites in rivers and reservoirs. 135 pharmaceuticals were analyzed using solid-phase extraction and ultra-performance liquid chromatography tandem mass spectrometry. The results showed that a total of 70 pharmaceuticals were present in the samples, and the most frequently detected ones included sulfonamides, macrolides, antiepileptic drugs, anti-inflammatory drugs, and β-blockers, etc. Amongst these, maximum concentrations of lincomycin, sulfamethoxazole, acetaminophen and paraxanthine were between 44 ng/L and 134 ng/L, and those of metoprolol, diphenhydramine, venlafaxine, nalidixic acid and androstenedione were less than 1 ng/L. Concentrations of the two that were most persistent, DEET and carbamazepine, were 0.8-10.2 ng/L and 0.01-3.5 ng/L, respectively. Higher concentrations of cotinine were observed in warm season than in cold season, while concentrations of lincomycin were the opposite. In a causality analysis, the occurrence of pharmaceuticals in DWSs depends mainly on the detection limits of the methods, their usage and the persistence in the aquatic environment.

“…DEET permits a total protection against mosquitoes bite for several hours (Fradin et al, 2002) and is known to be persistent (Costanzo et al, 2007) but weakly toxic toward fishes, birds and invertebrates (Pietrogrande et al, 2007). The majority of DEET enters waterways via sewage effluent following washing off and absorption/excretion by humans; almost 20% is adsorbed through skin, metabolized or excreted (Sudakin et al, 2003).…”

“…Even if DEET can be efficiently abated through advanced oxidation processes (AOPS) methods such as Fenton (Zhang et al, 2006;Zhang et al, 2007) and ozone treatment (Snyder et al, 2006), it was found at trace level in surface waters, groundwater and waters for human consumption (Sandstrom et al, 2005;Kolpin et al, 2004;Langford et al, 2008;Costanzo et al, 2007). DEET presence was detected in USA rivers, at an average concentration of 0.05 μg/L (Sandstrom et al, 2005); into 97% of surface waters in Australian Eastern coast at an average concentration of 0.093μg/L (Costanzo et al, 2007); in Europe, across river Rhine at concentration ranging from 15 to 30 ng/L (Schwarzbauer et al, 2005 Quednow and Püttmann, 2009), across Norway coast at concentrations 0.4-13 ng/L (Langford et al, 2008;Weigel et al, 2004), and in the North Sea, where it is considered as a ubiquitous pollutant with an average concentration of 1.1 ng/L in summertime (Weigel et al 2002).…”
