Abstract Municipal and industrial wastewater effluent is an important source of water for lotic systems, especially during periods low flow. The accumulated flows—expressed as a percentage total streamflow (ACCWW%)—contain chemical mixtures that pose risk to aquatic life; fish may be particularly vulnerable when chronically exposed. Although there has been considerable focus on individual-level effects exposure found in effluent, scaling up population-level remains challenging component needed better understand the potential consequences wild populations. This under changing climate which reuse could essential maintain river flows. We evaluated chronic measured by ACCWW%, relative abundance young-of-year (YOY), juvenile, adult smallmouth bass (Micropterus dolomieu) populations Shenandoah River Watershed (USA). increases ACCWW% previous year prespawn period were negatively correlated with YOY, resulting average 41% predicted decrease (range = 0.5%–94% abundance). lagged effect suggests reproductive performance compromised high ACCWW%. No relationships between juvenile or found, suggesting negative YOY offset due compensatory mechanisms following higher exposure.

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.

Global monitoring of persistent organic pollutants (POPs) has intensified following regulatory efforts aimed at reducing their release. In this context, we compiled over 10,000 POP measurements, reported from 1980 to 2023, assess the effectiveness these legislative measures in global marine environments. While a general decreasing trend legacy concentrations is evident across various maritime regions, highlighting success source control measures, Arctic Ocean and its marginal seas have experienced rise levels. This increase suggests northward migration via ocean currents mid-latitude regions polar areas. Despite reduce emissions, continued transport accumulation may substantial ecological impacts. Addressing environmental challenges demands thorough understanding dynamics, including response times, multiphase transport, biogeochemical cycling. Continued research into processes vital accurately map distribution temporal variations within systems.

Abstract Surface water concentrations of per- and polyfluoroalkyl substances (PFAS) potential for resulting biological effects were estimated in a study using Polar Organic Chemical Integrative Samplers (POCIS) from 60 tributary sites within 20 watersheds the Great Lakes Basin 2018. Sites represented range urban to agricultural, forested, wetland land uses included gradient wastewater treatment effluent zero 44% annual streamflow. Several also had airport influence. Twenty-one 32 targeted PFAS compounds detected POCIS samplers, which, 16 available sampling rates enabling time-weighted concentration estimates comparison with data. Estimated compared published quality guidelines (available nine PFAS), effect reported primary literature ECOTOX Knowledgebase apical endpoints (10 PFAS) non-apical vitro high-throughput screening data ToxCast (14 PFAS). Based on conservative evaluation approach that was weighted persistence limitations toxicological information, five individual PFAS, including Perfluorooctanesulfonic acid, Perfluorohexanesulfonic Perfluorobutanesulfonic Perfluorooctanoic Perfluorononanoic acid identified as warranting additional investigation.
