PFAS contamination in soil and sediment: Contribution of sources and environmental impacts on soil biota

Case Studies in Chemical and Environmental Engineering, Journal Year: 2024, Volume and Issue: 9, P. 100643 - 100643

Per- and polyfluoroalkyl substances (PFAS) have been detected in soils worldwide, suggesting that soil serves as a substantial reservoir for these compounds. This paper provides comprehensive overview of the origin PFAS contamination sediment, well environmental impacts associated with distribution mediums. In this review, we also discuss effects on microbes, plants, terrestrial food web, sediment benthic microorganisms. The highest concentration was found exposed to aqueous film-forming foam (AFFF), manufacturing biosolids, compared landfills, atmospheric deposition, industrial discharge, which are other three sources. Exposure has demonstrated negative richness, diversity, population structure bacterial species. It observed interfere regular functioning microorganisms, organisms sediment. Nevertheless, current data is insufficient grasp complete spectrum comprehensively. Moreover, accumulation vegetables, earthworms cause concern, they can eventually enter chain through trophic transfer processes. Finally, challenges possible strategies be implemented restrict dispersion sediments soil.

Further Insight into Extractable (Organo)fluorine Mass Balance Analysis of Tap Water from Shanghai, China

Environmental Science & Technology, Journal Year: 2023, Volume and Issue: 57(38), P. 14330 - 14339

The ubiquitous occurrence of per- and polyfluoroalkyl substances (PFAS) the detection unexplained extractable organofluorine (EOF) in drinking water have raised growing concerns. A recent study reported inorganic fluorinated anions German river systems, therefore, some samples, EOF may include anions. Thus, it might be more appropriate to use term "extractable fluorine (EF) analysis" instead analysis. In this study, tap samples (n = 39) from Shanghai were collected assess levels EF/EOF, 35 target PFAS, two (tetrafluoroborate (BF4-) hexafluorophosphate (PF6-)), novel PFAS through suspect screening potential oxidizable precursors oxidative conversion. results showed that ultra-short largest contributors accounting for up 97% ΣPFAS. To best our knowledge, was first time bis(trifluoromethanesulfonyl)imide (NTf2) China, p-perfluorous nonenoxybenzenesulfonate (OBS) also identified screening. Small amounts can oxidatively converted PFCAs noted after EF mass balance analysis revealed could only explain less than 36% EF. However, greatly reduced when BF4- PF6- included. These compounds further explained 44% EF, indicating role

Trends in the Analysis and Exploration of per- and Polyfluoroalkyl Substances (PFAS) in Environmental Matrices: A Review

Critical Reviews in Analytical Chemistry, Journal Year: 2023, Volume and Issue: 54(8), P. 3171 - 3195

Published: July 6, 2023

Per- and polyfluoroalkyl substances (PFAS) is an emerging class of organic pollutants concern now prevalent in environmental matrices including water, soil, air, biological. So far, several standard analytical methods have been developed to systematically analyze PFAS different matrices. However, the complexity makes effective extraction difficult, legacy gradually changing into a new with short chain unknown structure production, which analysis challenging. In this review, following aspects are summarized: (1) advances for matrices, further generalizes updating novel detection methods; (2) PFAS, suspect non-targeted screening method based on high-resolution mass spectrometry (HRMS) described.
