Pharmaceuticals and other contaminants of emerging concern in Admiralty Bay as a result of untreated wastewater discharge: Status and possible environmental consequences

The Science of The Total Environment, Journal Year: 2022, Volume and Issue: 835, P. 155400 - 155400

Published: April 22, 2022

Considering how the impact of human activity in Antarctica is growing, aim this study was to conduct first assessment pharmaceuticals and personal care products (PPCPs), other emerging contaminants (ECs), antibiotic resistance genes present western shore Admiralty Bay region King George Island. In total, more than 170 substances were evaluated assess potential environmental risks they pose area. The major source pollutants discharged untreated wastewater. highest PPCP concentrations wastewater found for naproxen (2653 ngL-1), diclofenac (747 ketoconazole (760 ibuprofen (477 ngL-1) acetaminophen (332 ngL-1). Moreover, benzotriazole (6340 caffeine (3310 also high. Risk Quotient values indicate that azole antifungals (ketoconazole), anti-inflammatories (diclofenac, ibuprofen) stimulants (caffeine) are main groups responsible toxic burden. addition, integrons (int 1) sulphonamide (sul 1-2) detected seawater. These results regular monitoring PPCPs ECs great importance environment. Additionally, following mitigation strategies suggested: (1) create a centralised record medications prescribed consumed situ (to improve knowledge without analysis); (2) use environmentally friendly substitutes both when possible (limiting consumption at source); (3) apply advanced systems treatment before discharge recipient (end-of-pipe technologies as final barrier).

From monitoring to treatment, how to improve water quality: The pharmaceuticals case

Chemical Engineering Journal Advances, Journal Year: 2022, Volume and Issue: 10, P. 100245 - 100245

Published: Jan. 10, 2022

Water pollution is the most serious problem threatening global water resources. The release of both natural and anthropogenic factors in aquatic environment affecting quality bodies, with Contaminants Emerging Concern (CECs) being one major issues. In recent years, availability robust sensitive analytical methods has allowed detection identification a wide variety pollutants. Pharmaceutically Active Compounds (PhACs) represent large category CECs detected environment, posing threats to human health ecosystems. Hence, there an urgent need for better understanding their environmental occurrence, fate, exposure-associated risks, degradation order regulate exposure pharmaceuticals environment. This review covers current trends, newly developed state-of-the-art methods, challenges PhACs different matrices, occurrence patterns We also make compressive assessment ineffective classic drinking treatment plants (DWTPs) novel technologies such as membrane filtration advanced oxidation processes that have been implemented upgrade DWTPs. Their efficiency removing here discussed, well other embryonic promising solutions. aim this article provide comprehensive summary pathways fate solutions improving monitoring assessments best removal plants.

Unveiling the existence and ecological hazards of trace organic pollutants in wastewater treatment plant effluents across China

Eco-Environment & Health, Journal Year: 2023, Volume and Issue: 3(1), P. 21 - 29

Published: Oct. 14, 2023

The presence of trace organic pollutants in the effluent wastewater treatment plants (WWTPs) poses considerable risks to aquatic organisms and human health. A large-scale survey 302 46 Chinese WWTPs was conducted gain an improved understanding their occurrence ecological risks. data showed that 216 compounds 11 chemical classes had been detected effluents. sum concentrations contaminants ranged from 1,392 ng/L 35,453 ng/L, with maximum concentration perfluoroalkyl substances (PFASs) recorded as highest (30,573 ng/L), which markedly less than reported 185,000 for 38 American WWTPs. bisphenol analogs (BPs) up 4,422 significantly higher those France, Germany, Japan, Korea, U.S. PFASs BPs were major pollutants, accounting 59% total pollution. Additionally, a 119 found have (RQ > 0.01). Among these, 23 1.0) warrant attention should be prioritized removal. This study lists valuable information controlling priority WWTP China.

Occurrence of emerging contaminants in three river basins impacted by wastewater treatment plant effluents: Spatio-seasonal patterns and environmental risk assessment

The Science of The Total Environment, Journal Year: 2024, Volume and Issue: 946, P. 174062 - 174062

Published: June 24, 2024

The concern on the fate and distribution of contaminants emerging (CECs) is a burning topic due to their persistence potential harmful effects. Particularly, antibiotics have received great attention implications in antimicrobial resistance occurrence. impact wastewater treatment plants (WWTP) remarkable, being one main pathways for introduction CECs into aquatic systems. combination novel analytical methodologies risk assessment strategies promising tool find out environmentally relevant compounds posing major concerns freshwater ecosystems impacted by those effluents. Within this context, multi-target approach was applied three Spanish river basins affected different WWTP treated effluents spatio-temporal monitoring chemical status. Solid phase extraction followed ultra-high-performance liquid chromatography were used quantification large panel (n = 270), including pharmaceuticals other consumer products, pesticides industrial chemicals. To end, water samples collected four sampling campaigns at locations each basin: (i) upstream from WWTPs; (ii) effluent discharge points (effluent outfall); (iii) downstream WWTPs (500 m downriver outfall). Likewise, 24-h composite provided all periods. First occurrence these assessed. Diverse seasonal trends observed depending group compounds, though COVID-19 outbreak variations certain pharmaceuticals. Detection frequencies concentrations generally exceeded measured low or non-quantifiable. Finally, risks associated with maximum contamination levels evaluated using two approaches account antibiotic selection as well. From studied 89 evidenced environmental least occasion study.
