The widespread occurrence of new and emerging persistent organic pollutants (NEPs POPs) in surface water poses a risk to drinking supply consequently human health. aim this work was investigate the potential transport 42 target NEPs POPs (including per-and polyfluoroalkyl substances (PFAS), pharmaceuticals, pesticides bisphenols) along rural urban environments three rivers England. type concentrations varied between sampling days points. Two pharmaceuticals (diclofenac ibuprofen), two (diethyl-meta-toluamide (DEET) prosulfocarb) range PFAS were detected above method detection limit. observed include restricted perfluorooctanoic acid (PFOA), perfluorooctanesulfonic (PFOS) newer generation substitute 6:2 fluorotelomer sulfonate (6:2 FTS). levels PFOS diclofenac all studied exceeded European environmental quality standard (EQS). high frequency river Ouse suggests their persistence contaminate connecting tributaries. An assessment ecological prosulfocarb samples from Ouse, using quotient method, showed algae, planktonic crustaceans, fish. Our results suggest that presence 12 POPs, could potentially be influenced by anthropogenic activities across rivers. study highlights need for continuous monitoring new-generation chemicals waters understand impact on ecosystem public

This study evaluated PFAS occurrence in rural well water and surface relative to land application of biosolids a tile-drained agriculture-dominated watershed. Spatial data were used identify potentially vulnerable wells based on their proximity biosolid-permitted location with respect groundwater flow. Water was collected from 103 private Greater Tippecanoe County Indiana 168 locations within the Region Great Bend Wabash River Overall, results indicate that (∑PFAS ≤ 169.4 ng/L) is more contamination than 15.7 ng/L). Short-chain perfluoroalkyl acids made up 72% ∑PFAS both sources. Nonetheless, long-chain homologues detected frequently (94%) (82%). Hierarchical cluster analysis identified biosolid-applied fields, WTTPs, industrial discharges as sources first-order streams high ∑PFAS. Temporal trends revealed an inverse relationship between streamflow concentrations sites impacted by point vice versa for diffuse sources, thereby providing complementary evidence potential The set did not show distinct spatial trend distance biosolid or characteristics.

Abstract Background Over 40% of the six million dry metric tons sewage sludge, often referred to as biosolids, produced annually in United States is land applied. Biosolids serve a sink for emerging pollutants which can be toxic and persist environment, yet their fate after application impacts on human health have not been well studied. These gaps our understanding are exacerbated by absence systematic monitoring programs defined standards protection. Methods The purpose this paper call critical attention knowledge that currently exist regarding biosolids underscore need evidence-based testing regulatory frameworks protection when A scoping review methodology was used identify research conducted within last decade, current standards, government publications applied biosolids. Results Current indicates persistent organic compounds, or pollutants, found pharmaceuticals personal care products, microplastics, per- polyfluoroalkyl substances (PFAS) potential contaminate ground surface water, uptake these from soil amended result contamination food sources. Advanced technologies remove contaminants wastewater treatment plant influent, effluent, destined along with tools detect quantify Conclusions To address risks, there needs significant investment ongoing infrastructure support advancements treatment; expanded manufacture use sustainable products; increased public communication risks associated overuse plastics; development implementation regulations protective environment.

We have investigated the occurrence, distribution, and biomagnification of per- polyfluoroalkyl substances (PFAS) in two tropical lakes (Asejire Eleyele) Southwestern Nigeria, with contrasting urban intensities. Over an 8-month period, we sampled sediment fish species (Clarias gariepinus: CIG; Oreochromis niloticus: ON; Coptodon guineensis: CG; Sarotherodon melanotheron: SM) across trophic levels, analyzed various PFAS congeners, addition to a select group toxicological responses. While herbivores (SM) benthic omnivores (CIG) at Asejire exhibited elevated levels PFBS PFOS, pelagic (ON) showed dominance PFDA, PFHxDA EtFOSE muscle. At Eleyele lake, patterns was dominated by PFBS, EtFOSE, PFPeS, PFOcDA PFOS (SM, CG), omnivore (ClG).
