The complex effect of dissolved organic carbon on desorption of per- and poly-fluoroalkyl substances from soil under alkaline conditions

Environmental Pollution, Journal Year: 2024, Volume and Issue: 356, P. 124234 - 124234

Published: May 28, 2024

Per- and poly-fluoroalkyl substances (PFASs) are contaminants of emerging concern, yet the understanding factors that control their leaching release from contaminated soils remains limited. This study aimed to investigate impact dissolved organic carbon (DOC) on PFASs-specifically, perfluorohexane sulfonate (PFHxS), perfluorooctane (PFOS), perfluorooctanoic acid (PFOA)from by aqueous film forming foam (AFFF). Batch experiments were conducted AFFF-contaminated under alkaline solution conditions (pH 9.5, 10.5, 12) as it enhances both PFAS DOC. Leaching PFOS was significantly increased conditions. Although generally with pH, appeared be more retained very pH used in this study. At same DOC less Ca(OH)

Air Bubbling Assisted Soil Washing to Treat PFAS in High Organic Content Soils

Environments, Journal Year: 2025, Volume and Issue: 12(1), P. 20 - 20

Published: Jan. 12, 2025

The soil-washing technique has been successfully utilized for the remediation of PFAS-contaminated soils. Prior studies have shown that organic carbon (OC) content and grain size soil determined efficiency PFAS removal during washing. However, most past focused on soils with a low OC content, typically ranging from 0–3%. In this study, we explored use novel process where washing was combined air bubbling (or foam fractionation) to aid in high OC-content (~4–20%). Treatment (~20%) perfluorobutane sulfonate (PFBS) perfluorooctanoate (PFOA) did not enhance their removal, as they featured surface activity. observed an improvement extraction perfluorooctane (PFOS) 27% 42% bubbling, consistent higher activity PFOS compared PFOA PFBS. Perfluorodecanoic acid (PFDA) irreversibly adsorbed removed efficiently by both A slight PFDA (6–13%) when co-surfactant (cetyltrimethylammonium chloride) added reduced ~4% addition nonorganic sand contaminated prior This suggested interaction dominant factor determining its soil. conclusion, our results indicated alone sufficient short-chain Although had mild effect some long-chain solution, it help overall soils, highlighting difficulty treatment immobilization would be ideal approach managing such sites.

Published: March 11, 2025

Per- and polyfluoroalkyl substances (PFASs) are found everywhere, including food, cosmetics, pharmaceuticals. This review introduces PFASs comprehensively, discussing their nature identifying interconnection with microplastics impacts on public health the environment. The human cost of decades delay, cover-ups, mismanagement plastic waste is outlined briefly explained. Following that, long-term effects critically assessed. Risk assessment then reviewed, mentioning different tools models. Scientific research in United States America analyzed, taking into consideration Center for Disease Control (CDC)'s PFAS Medical Studies Guidelines. impact activities studies around world have focused levels food products dietary intake countries such as China, European countries, USA Australia. Moreover, drinking water regard to risks, mitigation, regulatory needs, account chemical contaminants safety. Finally, briefings specific regions discussed, referring Australia, Vietnam, Canada, Europe, (USA), South America, Africa. crisis a multifaceted issue, exacerbated by mismanagement, it discussed context applying following problem-solving analytical tools: Domino Effect Model accident causation, Swiss Cheese Theory Model, Ishikawa Fish Bone Root Cause Analysis. Last but not least, PFASs' Sustainable Development Goals (SDGs) 2030 rigorously discussed.
