Occurrence, Concentration, and Distribution of 35 PFASs and Their Precursors Retained in 20 Stormwater Biofilters

Environmental Science & Technology, Journal Year: 2024, Volume and Issue: 58(32), P. 14518 - 14529

Current knowledge about the fate and transport behaviors of per- polyfluoroalkyl substances (PFASs) in urban stormwater biofilter facilities is very limited. C5–14,16 perfluoroalkyl carboxylic acids [perfluorinated (PFCAs)], C4,8,10 perfluoroalkanesulfonic (PFSAs), methyl-perfluorooctane sulfonamide acetic acid (MeFOSAA, a PFSA precursor), unknown C6–8 PFCA perfluorooctanesulfonic precursors were frequently found bioretention media forebay sediments at Σ35PFAS concentrations <0.03–19 0.064–16 μg/kg-DW, respectively. Unknown precursor up to ten times higher than corresponding PFCAs, especially forebays biofilters' top layer. No significant trend could be attributed PFAS versus depth filter media, though 2–3 upper layers on average (significant difference between (0–5 cm) deepest (35–50 layer). PFASs had similar spatial concentration distribution each (no clear short- long-chain PFASs). Commercial land use organic matter important factors explaining variations among biofilters sampling depths, Given comparable accumulations deeper superficial possible increased mobility after biotransformation, designing shallow-depth, nonamended sand or maintaining only layer may insufficient for management.

Leading Techniques for Per- and Polyfluoroalkyl Substances (PFASs) Remediating in Water and Wastewater

Water, Journal Year: 2025, Volume and Issue: 17(9), P. 1319 - 1319

Published: April 28, 2025

Per- and polyfluoroalkyl substances (PFASs), a class of synthetic organic compounds since the 1940s, have become widespread persistent environmental pollutants. Due to their high chemical stability, bioaccumulation potential, extensive industrial household applications, PFASs drawn significant attention from researchers worldwide in recent years, while hot topic, publications are updated very quickly. Various remediation technologies, including adsorption, pyrolysis, biodegradation, advanced oxidation, been developed treated as leading techniques mitigate PFAS contamination. Other alternative foam fractionation, constructed wetland, piezoelectric ball milling. However, effectiveness these methods varies depending on reaction mechanisms, operational conditions, factors. This review provides comprehensive summary latest advancements removal strategies, highlighting advantages, limitations, potential synergies. Furthermore, future research directions technological developments discussed explore more efficient, sustainable, cost-effective solutions for remediation.

Recent Advancements in Per- and Polyfluoroalkyl Substances (PFAS) Detection by Sensors and Surface-Enhanced Raman Scattering (SERS) Method: A Review

Published: Jan. 22, 2024

Per- and polyfluoroalkyl substances (PFAS), a large group of developing contaminants, have recently become the subject increased concern due to their potentially hazardous effects. They are classified as poisonous that can be found in variety aquatic situations. The widespread usage PFAS across numerous industries has resulted high environmental biological accumulation substance. Identification elimination from environment is crucial since they tenacious potential cause cancer. Traditional methods content assessment, while useful some cases, often inadequate for continuing control monitoring. Within academia, there noticeable desire rapid, cost-effective, durable, readily transportable techniques targeted at detecting compounds field settings. As result, labs other governmental non-governmental bodies may start testing more mandated by legislation. PFAS-detecting sensors, which offer an innovative solution applied situ affordable simple use, emerged promising method assessment based on existing research. In addition, it give administrators users water worldwide information use. This article provides thorough summary recent developments, limitations, performance considerations detection sensors. Surface-enhanced Raman scattering (SERS) also been covered because its excellent sensitivity specificity pollutants, making sensing PFAS. Intelligent systems should benefit this

Probing the microbiome in stormwater pipeline sediments: Co-occurrence patterns and novel functionalities

Current Research in Biotechnology, Journal Year: 2024, Volume and Issue: 7, P. 100199 - 100199

Published: Jan. 1, 2024

Stormwater pipeline is an essential pathway to transfer stormwater runoff into nearby receiving water bodies. Understanding the composition, co-occurrence patterns, and function of microbial communities in sediments can help provide management control strategies for pollution safeguard safety ecological health urban environment. This study employs 16S rRNA gene amplicon sequencing probe a highly urbanized area Guangzhou, China. Results show that sediment bacterial community rich Listeria, Prevotella, Stenotrophomonas, Pseudomonas, which all pertain pathogens. Methanogens (Methanobacterium, Methanosaeta, Methanosarcina, Methanobrevibacter) ammonia-oxidizing archaea (Ca. Nitrosopelagicus, Ca. Nitrososphaera, Nitrosotenuis) dominated archaeal sediments. These functions are further validated by prediction overall community. The network microbe-environment correlation analyses suggest particulate C-N-P components play more crucial role, comparison dissolved ones regulating microbiome, although not samples follow this mechanism. findings expected contribute systems valuable guidance improving environmental well-being ecosystems.
