Suspect-screening analysis of a coastal watershed before and after Hurricane Florence using high-resolution mass spectrometry
SCIENCE OF THE TOTAL ENVIRONMENT, 782.
author keywords: HRMS; Wastewater; Water reuse; Forest; Emerging contaminant; Suspect screening
TL;DR:
The data suggest that the land treatment system is functionally and hydrologically robust to extreme storm events and contributed to dilution of upstream chemical reservoirs for downstream receiving waters for months after the storm.

Expanding phytoremediation to the realms of known and unknown organic chemicals of concern
International Journal of Phytoremediation, 21(14), 1385–1396.
author keywords: HRMS; organic contaminant; nontarget; phytoremediation; exposome; pollutome
MeSH headings : Biodegradation, Environmental; Environmental Pollutants; Gas Chromatography-Mass Spectrometry; Mass Spectrometry; Organic Chemicals
TL;DR:
This review provides an overview of targeted, suspect screening, and nontarget HRMS approaches, summarizes the expanding knowledge of regulated and unregulated organic chemicals in the environment, addresses requisite HRMS instrumentation, analysis cost, uncertainty, and data processing techniques, and offers potential bridges of HRMS analyses to phytoremediation research and application.

Suspect screening and prioritization of chemicals of concern (COCs) in a forest-water reuse system watershed
Science of The Total Environment, 694, 133378.
author keywords: HRMS; Suspect screening; Wastewater; Forest; Exposome
TL;DR:
Assessing chemical features in ground- and surface waters from a watershed where secondary-treated wastewater is irrigated onto 900 ha of temperate forest offers a more holistic view of chemicals that contribute to the exposome, suggesting that though wastewater may be a source of chemicals to ground and surface Waters on-site, dissipation of wastewater-derived features likely occurs with limited off-site surface water export by the forested land treatment system.

Behaviour of freshwater snails (Radix balthica) exposed to the pharmaceutical sertraline under simulated predation risk
Ecotoxicology.
author keywords: Pharmaceuticals; Behavioural toxicology; Freshwater toxicology; Snail; Predation; Boldness
MeSH headings : Animals; Selective Serotonin Reuptake Inhibitors / toxicity; Sertraline / toxicity; Snails / physiology; Toxicity Tests; Water Pollutants, Chemical / toxicity
TL;DR:
There were no effects of sertraline on NCEs, and there were observed effects of chemical cue from predatory fish on snail behaviour independent of sERTraline exposure, which raises questions on the modes of action of various SSRIs in gastropods, as well as the potential for a trophic “mismatch” of effects between fish predators and snail prey in aquatic systems.

Comparison of emerging contaminants in receiving waters downstream of a conventional wastewater treatment plant and a forest-water reuse system
Environmental Science and Pollution Research, 25(13), 12451–12463.
Contributors: A. McEachran n, n , S. Newton *, R. McMahen*, M. Strynar *, D. Shea n , E. Nichols n
author keywords: Wastewater; Contaminants of emerging concern (CECs); Forest-water reuse; Nontargeted analysis; Surface water; Water reuse
MeSH headings : Agricultural Irrigation; Environmental Monitoring; Forestry / methods; North Carolina; Waste Disposal, Fluid / methods; Wastewater / analysis; Water Pollutants, Chemical / analysis
TL;DR:
Data indicate that FWR systems represent a sustainable wastewater treatment alternative and that emerging contaminant release to waterways was lower at a FWR system than a conventional WWTP.

Assessing Potential Vulnerability and Response of Fish to Simulated Avian Predation after Exposure to Psychotropic Pharmaceuticals
Toxics.
author keywords: sertraline; fluoxetine; propranolol; SSRI; beta-blocker; fish; bird; behavior; predation
TL;DR:
None of the substances significantly affected swimming activity of the fish, nor did they increase vulnerability by affecting encounter probability or evasive endpoints compared to control treatments, and counter to expectations, fish exposed to 100 μg/L fluoxetine were less likely to enter the open area of the arena.

Ecological implications of altered fish foraging after exposure to an antidepressant pharmaceutical
Aquatic Toxicology, 151, 84–87.
Contributors: * , P. Nilsson * & O. Berglund*
author keywords: Pharmaceutical; Sertraline; Fish; Functional response; Foraging ecology
MeSH headings : Animals; Daphnia / physiology; Feeding Behavior / drug effects; Perches / physiology; Sertraline / toxicity; Water Pollutants, Chemical / toxicity
TL;DR:
Feed trials using juvenile Eurasian perch exposed to the selective serotonin reuptake inhibitor (SSRI) sertraline are performed to test the hypothesis that sERTraline alters foraging ecology of the fish in terms of their functional response, and found an exposure-dependent decrease in feeding with increasing sertrals.

Pharmaceuticals and personal care products (PPCPs) in treated wastewater discharges into Charleston Harbor, South Carolina
Science of the Total Environment, 437, 1–9.
Contributors: * , Y. Sapozhnikova, P. Pennington*, A. Clum, A. Fairey & E. Wirth *
author keywords: Pharmaceutical; Hormone; EPA Method 1694; Influent; Effluent; Estuary
MeSH headings : Nonprescription Drugs / analysis; Pharmaceutical Preparations / analysis; Seasons; Seawater / analysis; South Carolina; Wastewater / analysis; Wastewater / chemistry; Water Pollutants, Chemical / analysis; Water Purification; Water Quality
TL;DR:
Seasonal and regional trends of pharmaceuticals and personal care products detected in monthly samples from two local wastewater treatment plants in Charleston, South Carolina, USA, over the period of one year indicate reduced degradation in colder months in wastewater and surface water.
