PFASs are linked to serious health and environmental concerns. Among their widespread applications, known be used in food packaging directly contribute human exposure. However, information about is scattered. Therefore, we systematically map the evidence on detected migrates extracts of contact materials provide an overview available hazard biomonitoring data. Based FCCmigex database, 68 have been identified various materials, including paper, plastic, coated metal, by targeted untargeted analyses. 87% these belong perfluorocarboxylic acids fluorotelomer-based compounds. Trends chain length demonstrate that long-chain perfluoroalkyl continue found, despite years global efforts reduce use substances. We utilized ToxPi illustrate data for only 57% packaging. For those which toxicity testing has performed, many adverse outcomes reported. The knowledge gaps presented here support international proposals restrict as a group, protect health.

Trace detection of perfluorooctanoic acid and perfluorooctane sulfonate in surface sediments using a liquid chromatograph coupled to an electrospray ionization single quadrupole mass spectrometer (LC-ESI–Q-MS)

Microchemical Journal, Journal Year: 2024, Volume and Issue: 199, P. 109928 - 109928

Poly- and perfluoroalkyl substances (PFAS) are among the pollutants of environmental concern besides pharmaceuticals personal care products, microplastics, other persistent organic pollutants. Of all different PFASs reportedly present in environment, most researched perfluorooctanoic acid (PFOA) perfluorooctane sulfonic (PFOS). In this study, these were detected using a precise, selective, sensitive liquid chromatographic-electrospray ionization single quadrupole mass spectrometric (LC-ESI–Q-MS) method within linear range 0.002–0.02 μg/mL. The developed was thereafter validated according to ICH validation parameters. This used monitor PFOA PFOS selected surface sediments collected environs two prominent rivers KwaZulu-Natal province South Africa: Umgeni Palmiet Rivers. While levels varied from not 1.490 ng/g dw, ranged 0.206 dw 0.426 total concentration (∑ ∑ PFOS) sediment samples 7.50 2.79 respectively. percent positive occurrence tested 81.8 % 100 %, study becomes an eye opener commencement research works with respect developing remediation strategies for removal PFAS especially African environment.

Target and suspect per- and polyfluoroalkyl substances in fish from an AFFF-impacted waterway

The Science of The Total Environment, Journal Year: 2023, Volume and Issue: 906, P. 167798 - 167798

A major source of toxic per- and polyfluoroalkyl substances (PFAS) is aqueous film-forming foams (AFFF) used in firefighting training at airports military installations, however, PFAS have many additional sources consumer products industrial processes. field study was conducted on fish tissues from three reaches the Columbia Slough, located near Portland International Airport, OR, that are affected by AFFF other sources. Fishes including largescale sucker (Catostomus macrocheilus), goldfish (Carassius auratus), largemouth bass (Micropterus salmoides) were collected 2019 2020. Fish blood, liver, fillet (muscle) analyzed for target suspect liquid chromatography high resolution mass spectrometry (LC-HRMS). Data patterns species, tissue type, river reach. Thirty-three out 50 compounds detected least once during study, concentrations up to 856 ng/g. Seven carboxylic acids (PFOA, PFNA, PFDA, PFUdA, PFDoA, PFTrDA, PFTeDA), sulfonates (PFHxS, PFOS, PFDS), electrofluorination-based (FBSA, FHxSA, FOSA), two fluorotelomer-based (8:2 FTS, 10:2 FTS) most frequently all types. The C6 (PFHxS) C10 (PFDS) homologs with PFOS FHxSA 1-3 orders magnitude greater than detected. This first report Cl-PFOS, FPeSA, FHpSA tissue. In samples, lowest, followed blood highest. Differences driven primarily types a lesser extent but weakly Oregon Health Authority modified an existing consumption advisory Slough recommend no whole-body avoid elevated levels liver. Measured indicate potential adverse ecological effects.
