“…Designed-bioactive (e.g., pharmaceuticals, pesticides, hormones) organic contaminants originate from numerous human and agricultural-animal sources, are ubiquitous in surface water, and directly threaten the structure and function of aquatic ecosystems [1][2][3][4][5]. Pharmaceuticals generally target evolutionarily conserved (present in multiple species) molecular endpoints [6][7][8][9][10], exhibit high aqueous mobility [11,12] and pH-variable activity [13], and occur as complex environmental cocktails [14,15], resulting in multiple modes of action and a range of adverse outcomes in aquatic foodwebs [5,[16][17][18][19][20][21][22][23][24][25][26].…”

Organic contaminants with designed molecular bioactivity, such as pesticides and pharmaceuticals, originate from human and agricultural sources, occur frequently in surface waters, and threaten the structure and function of aquatic and terrestrial ecosystems. Congaree National Park in South Carolina (USA) is a vulnerable park unit due to its location downstream of multiple urban and agricultural contaminant sources and its hydrologic setting, being composed almost entirely of floodplain and aquatic environments. Seventy-two water and sediment samples were collected from 16 sites in Congaree National Park during 2013 to 2015, and analyzed for 199 and 81 targeted organic contaminants, respectively. More than half of these water and sediment analytes were not detected or potentially had natural sources. Pharmaceutical contaminants were detected (49 total) frequently in water throughout Congaree National Park, with higher detection frequencies and concentrations at Congaree and Wateree River sites, downstream from major urban areas. Forty-seven organic wastewater indicator chemicals were detected in water, and 36 were detected in sediment, of which approximately half are distinctly anthropogenic. Endogenous sterols and hormones, which may originate from humans or wildlife, were detected in water and sediment samples throughout Congaree National Park, but synthetic hormones were detected only once, suggesting a comparatively low risk of adverse impacts. Assessment of the biodegradation potentials of 8 C-radiolabeled model contaminants indicated poor potentials for some contaminants, particularly under anaerobic sediments conditions.

“…Treated wastewater discharge can be essential for downstream-flow and other surface-water-supply requirements (National Research Council, 2012) but directly threatens down-gradient aquatic ecosystem health (Dong et al, 2015;Jobling et al, 2008;Kidd et al, 2007;Kramer et al, 1998;McGee et al, 2009;Nash et al, 2004;Painter et al, 2009;Rosi-Marshall et al, 2013;Vajda et al, 2008) as well as surface-water and groundwater drinking-water quality (Diaz-Cruz and Barcelo, 2008;Foster and Chilton, 2004;Hamann et al, 2016;Lapworth et al, 2012;Lewandowski et al, 2011). Pharmaceuticals are of particular concern due to: 1) relative solubility and high mobility in aqueous environments compared with many other wastewater contaminants; 2) designed high bioactivities and biorecalcitrance; and 3) a wide range of potential ecological endpoints including, toxicity (Han et al, 2006;Oliveira et al, 2015;Quinn et al, 2008;Rosi-Marshall et al, 2013;Xie et al, 2016), endocrine disruption (Kidd et al, 2007;Niemuth et al, 2015;Painter et al, 2009;Vajda et al, 2008), immuno-modulation (Canesi et al, 2007;Gust et al, 2013), antibiotic resistance selection (Haack et al, 2012;Martinez, 2009), as well as cytotoxicity and mutagenesis (Buerge et al, 2006;Johnson et al, 2008).…”

Downstream transport and fate of wastewater contaminants including pharmaceuticals are intensively studied in fluvial systems (see for example, Acuña et al, 2015;Barber et al, 2013;Bradley et al, 2009;Bradley et al, 2007;Bradley and Journey, 2014;Brown et al, 2009;Dong et al, 2015;Fono et al, 2006;Kunkel and Radke, 2011;Lin et al, 2006;Radke et al, 2010;Writer et al, 2012). Surface-water/groundwater contaminant exchange and the fate of surface-water-derived groundwater contaminants, however, are poorly understood in comparison; a critical scientific data gap given the global importance of subsurface freshwater supplies (Oelkers et al, 2011;Schwartz and Ibaraki, 2011;U.S.…”

“…The treatment of domestic sewage results in the production of considerable volumes of wastewater every day, a large proportion of which is discharged into natural waterways (Dong et al, 2015). Most widely used treatment technologies are not entirely effective at removing chemicals (Calisto and Esteves, 2009;Maier et al, 2015), and wastewater discharge is, therefore, a major source for various classes of contaminants to enter aquatic-receiving environments (la Farré et al, 2008;Kaplan, 2013;Jasinska et al, 2015).…”

Diurnal activity patterns as a sensitive behavioural outcome in fish: effect of short‐term exposure to treated sewage and a sub‐lethal PPCP mixture

Sub-lethal toxicological responses are common occurrences in aquatic animals exposed to sewage wastewater and organic wastewater contaminants. Behavioural alterations are particularly sensitive indicators of sub-lethal toxicological stress in animals exposed to various pollutants, and often correlate with higher-level outcomes. Diurnal activity patterns in many fish species are sensitive to changes in natural biotic factors, but few studies have explored how environmental pollutants influence such rhythms. We investigated diurnal activity patterns in the mosquitofish (Gambusia holbrooki), after exposure to UV-treated sewage and a mixture of key contaminants identified through chemical analysis and subsequent risk-based prioritization of the wastewater. Exposure to 50% and 100% wastewater abolished daytime activity levels in male, but not female fish. Chemical analysis identified fluoxetine, diazinon and triclosan above their reported predicted-no-effect-concentrations (PNECs), and fish were thus exposed to a mixture of these compounds at 1, 10 and 100 μg l -1. Behavioural responses were highly consistent between fish exposed to wastewater and the contaminant mixture, indicating that these prioritized contaminants are indeed likely contributing to the observed effects. Effective concentrations of the mixture were considerably lower than those reported as eliciting behavioural effects in previous studies exploring each of these compounds alone. Results warn of the potential for negative higher-level consequences associated with exposures of fish to common organic wastewater contaminants, as altered diurnal activity patterns could conceivably scale-up to influence performance including foraging success and predator avoidance. Further research is necessary to increase our understanding of linkages between alterations to diurnal activities and effects at the population level.
