Environmental pollution by per- and polyfluoroalkyl substances (PFAS), commonly known as "forever chemicals", is a major concern. Numerous studies have identified PFAS in various environmental matrices including groundwater, surface water, sea, soil, atmosphere. Nevertheless, the atmospheric presence of remains an underexplored area. The exact sources atmosphere mechanisms governing their transfer remain largely elusive. In this study, we investigated, for first time, influence aeration on aqueous-to-air transfer, range short-, medium-, long-chain from aqueous solutions contaminated with at concentrations pHs relevant to those industrial wastewater treatment. enriched aerosols were generated under three tested pH conditions which found affect partitioning individual PFAS. extent aerosolisation also showed clear dependence analyte's carbon chain length functional groups. Specifically, propensity into increased increasing length. Notably, perfluorosulfonic acids (PFSA) demonstrated greater potential compared perfluorocarboxylic (PFCA).

Our results suggest that processes involving water (including industry) could potentially act source

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

Exploring per- and polyfluoroalkyl substance distribution in Arctic wastewater treatment lagoons and natural wetlands: First record in Nunavik, Canada

Chemosphere, Journal Year: 2025, Volume and Issue: 374, P. 144186 - 144186

Per- and polyfluoroalkyl substances (PFAS), as emerging bioaccumulative contaminants, are widely present in water wastewater systems. Municipal effluents serve pathways for PFAS to enter aquatic environments. This study monitors the treatment lagoons, nearby wetlands bay a Canadian Arctic community. Eight out of 40 targeted were detected samples collected from raw wastewater, natural wetlands, Ungava bay. The total concentrations ranges 45.9-56.1 ng/L 36.6-70.8 measured at 7.3 most prevalent frequently 6:2 FTS, PFHxA, PFNA. At all sites, short-chain surpassed long-chain PFAS. Short-chain peaked 267.01 (79.74%), while totaled 67.83 (20.26%). estimated yearly mass flow rate into environment through lagoon effluent was 2.33 g/year. conducted environmental risk assessment both lagoons three downstream suggests that risks associated with under posed minimal ecological risk, though long-term evaluation is needed. In conclusion, findings this research provide further information on pollution regions may, such, guide development comprehensive regulations safeguard human health environment, thereby mitigating potential future risks.
