Adsorption of PFAS onto secondary microplastics: A mechanistic study

Journal of Hazardous Materials, Год журнала: 2024, Номер 470, С. 134185 - 134185

Microplastics (MPs) are abundant in aquatic systems. The ecological risks of MPs may arise from their physical features, chemical properties, and/or ability to concentrate and transport other contaminants, such as per- polyfluoroalkyl substances (PFAS). PFAS have been extracted found natural waters. Still, there needs be a mechanistic investigation the effect chemistry water physicochemical properties on how partition onto secondary MPs. Here, we studied influence pH, organic matter (NOM), ionic strength, temperature adsorption generated PET bottles. was thermodynamically spontaneous at 25 °C, based Gibb's free energy (ΔG = -16 -23 kJ/mol), primarily due increased entropy after adsorption. Adsorption reached equilibrium within 7-9 h. Hence, will surface hours fresh saline Natural decreased capacity for through electrosteric repulsion, while higher strength favored by decreasing electrostatic repulsion. Increased pH which negated study provides fundamental information developing models predict interactions between PFAS.

Alarming concern over the persistence and toxicity of per- polyfluoroalkyl substances (PFAS) in environment has created an imperative need for designing redesigning strategies their detection remediation. Conventional PFAS removal technologies that uses physical, chemical, or biological methods. Increase diversity quantity entering necessitated developing more advanced integrated removal. Despite advances reported this domain, there exist a huge research gap to be mentored tackle problems associated with mitigation combined wide variety environment. The possibility combine other emerging contaminants poses additional threat existing treatment methods thereby stressing continuous monitoring updating processes. This review work aims at understanding structure, entry, fate different types Further in-depth discussion regarding levels is elaborated review. process description recent remediation techniques along significance, limitations integration discussed detail. detailed outlook on advantages insight into recently developed outlined

Overview of Per- and Polyfluoroalkyl Substances (PFAS), Their Applications, Sources, and Potential Impacts on Human Health

Pollutants, Год журнала: 2024, Номер 4(1), С. 136 - 152

Опубликована: Март 6, 2024

Per- and polyfluoroalkyl substances (PFAS) belong to a group of synthetic compounds that have recently raised concerns about human health environmental quality due their great prevalence, degradation resistance, potential toxicity. This review focuses on the applications PFAS effects health. Specific emphasis has been laid (i) application/use PFAS, (ii) sources distribution in diverse compartments, (iii) impact Significant humans are associated with exposure i.e., immunotoxicity, thyroid kidney disorders, cancer, etc. Conclusions obtained from studies demonstrate inadequate evidence should not be used justify delaying risk reduction steps for alternatives. can determined different matrices using both traditional analytical approaches, liquid chromatography coupled mass spectrometry (LC-MS/MS) semi-quantitative passive sampling, advanced methods colorimetric, spectrofluorimetric, electrochemical detection. Traditional costly broadly available, while emerging, cost-effective less sensitive unable meet regulatory limits. There is still significant number performed fully comprehend real contamination by PFAS.

Inconsistencies in the EU regulatory risk assessment of PFAS call for readjustment

Environment International, Год журнала: 2024, Номер 186, С. 108614 - 108614

Recognition of per- and polyfluoroalkyl substances (PFAS) as widespread environmental pollutants a consequent risk to human health, has recently made the European Union (EU) adopt several regulatory measures for their management. The coherence these is challenged by diversity ubiquitous occurrence PFAS, which also complicates EU's endeavor advance justified, harmonized, transparent approaches in assessment chemical risks. Our study critically reviews approach applying comparative analysis current pending thresholds issued chemicals water bodies, drinking water, certain foodstuffs. shows that level health protection embedded studied may differ three orders magnitude, even similar exposure settings. This likely confuse common understanding toxicity risks PFAS undermine reasonable decision-making equal treatment different stakeholders. We indicate currently, no consensus exists on appropriate required regarding adopted tolerable intake value EU too cautious. Based our analysis, we propose some simple solutions how regulations implicit or application could be improved. further conclude instead setting EU-wide all compartments, providing member states with flexibility consider case-specific factors, such regional background concentrations food consumption rates, national procedures would result more sustainable management without compromising scientific foundation assessment, legitimacy policy framework public health.
