Published: Sept. 9, 2019

Abstract This annual review covers the literature published in 2018 on topics related to occurrence and fate of environmental pollutants wastewater. Due vast amount this topic, we have discussed only a portion quality research publications, due limitation space. The abstract search was carried out using Web Science, abstracts were selected based their relevance. In few cases, full‐text articles referred understand new findings better. is divided into following sections: antibiotic‐resistant bacteria (ARBs) genes (ARGs), disinfection by‐products (DBPs), drugs abuse (DoAs), estrogens, heavy metals, microplastics, per‐ polyfluoroalkyl compounds (PFAS), pesticides, pharmaceuticals personal care products (PPCPs), with addition two classes previous years (DoAs PFAS).

Water, Water Everywhere, but Every Drop Unique: Challenges in the Science to Understand the Role of Contaminants of Emerging Concern in the Management of Drinking Water Supplies

Abstract The protection and management of water resources continues to be challenged by multiple ongoing factors such as shifts in demographic, social, economic, public health requirements. Physical limitations placed on access potable supplies include natural human‐caused aquifer depletion, aging infrastructure, saltwater intrusion, floods, drought. These factors, although varying magnitude, spatial extent, timing, can exacerbate the potential for contaminants concern (CECs) present sources drinking water, premise plumbing associated tap water.

It is not intended read one sitting, but instead a starting point scientists wanting learn more about surrounding CECs. text discusses topical evolution over time (Section 1), improvements measuring chemical microbial CECs, through both analysis concentration toxicity 2) modeling CEC exposure fate 3), forms treatment effective at removing 4), human impacts from 5). paper concludes with changes quantity, scarcity surpluses, could affect quality 6).

High mortality in aquatic predators of mosquito larvae caused by exposure to insect repellent

Biology Letters, Journal Year: 2018, Volume and Issue: 14(10), P. 20180526 - 20180526

Published: Oct. 1, 2018

In the face of mosquito-borne disease outbreaks, effective mosquito control is a primary goal for public health. Insect repellents, containing active compounds such as DEET and picaridin, are first defence against biting insects. Owing to widespread use incomplete sewage treatment, these frequently detected in surface waters, but their effects on aquatic taxa larvae or naturally occurring predators poorly understood. We investigated environmentally realistic concentrations commercial products picaridin survivorship larvae, potential indirect survival larval salamanders, major predator larvae. Larval mosquitos were not affected by exposure repellents picaridin. found no salamander mortality treatments, rates treatments ranged from 45 65% after 25 days exposure. Salamander exposed began display tail deformities impaired development four experiment began. Our findings suggest possibility that picaridin-containing waters may increase abundance adult owing decreased predation pressure.

Effects-Based Monitoring of Bioactive Chemicals Discharged to the Colorado River before and after a Municipal Wastewater Treatment Plant Replacement

Environmental Science & Technology, Journal Year: 2020, Volume and Issue: 55(2), P. 974 - 984

Published: Dec. 29, 2020

Monitoring of the Colorado River near Moab, Utah, wastewater treatment plant (WWTP) outflow has detected pharmaceuticals, hormones, and estrogen-receptor (ER)-, glucocorticoid receptor (GR)-, peroxisome proliferator-activated receptor-gamma (PPARγ)-mediated biological activities. The aim present multi-year study was to assess effects a WWTP replacement on bioactive chemical (BC) concentrations. Water samples were collected bimonthly, pre- post-replacement, at 11 sites along upstream downstream analyzed for in vitro bioactivities (e.g., agonism ER, GR, PPARγ) BC concentrations; fathead minnows cage deployed post-replacement with varying proximities WWTP. Before replacement, ER (24 ng 17β-estradiol equivalents/L)-, GR (60 dexamethasone PPARγ-mediated activities but diminished downstream. In March 2018, effluent acutely toxic fish, likely due elevated ammonia Following PPARγ reduced by approximately 60–79%, no toxicity observed caged there marked decreases concentrations many BCs. Results suggest that Moab achieved significant reduction River.

Terrestrial protected areas do not fully shield their streams from exogenous stressors

Summary Protected areas (PAs) represent a powerful refuge for maintaining and safeguarding biodiversity. Generally, PAs are delineated to protect terrestrial taxa, providing incidental protection the aquatic ecosystems within their borders. Here, we compare water quality non-PAs in southern Brazil, encompassing remnants of Atlantic Forest biome, assess whether serve as buffer from external pressures boundaries. In addition physicochemical microbiological parameters, analysed 147 pesticide 31 pharmaceutical compounds samples 33 sites outside PAs.

Changes in chemical occurrence, concentration, and bioactivity in the Colorado River before and after replacement of the Moab, Utah wastewater treatment plant

The Science of The Total Environment, Journal Year: 2023, Volume and Issue: 904, P. 166231 - 166231

Long-term (2010-19) water-quality monitoring on the Colorado River downstream from Moab Utah indicated persistent presence of Bioactive Chemicals (BC), such as pesticides and pharmaceuticals. This stream reach near Canyonlands National Park provides critical habitat for federally endangered species. The wastewater treatment plant (WWTP) outfall discharges to is nearest potential point-source this reach. original WWTP was replaced in 2018.
