ClearReview of Recent Computational Research on the Adsorption of PFASs with a Variety of Substrates
This review summarizes recent computer modeling research on how PFAS, sometimes called "forever chemicals," stick to various materials, which could help develop better cleanup methods. While focused on PFAS rather than microplastics, both are persistent environmental pollutants that resist breakdown and accumulate in the body. Understanding how these chemicals interact with surfaces at the molecular level could lead to more effective ways to remove them from contaminated water and soil.
Firefighters’ exposure to per-and polyfluoroalkyl substances (PFAS) as an occupational hazard: A review
This review examines how firefighters face elevated cancer risk from occupational exposure to PFAS, a class of toxic "forever chemicals" found in their protective gear, firefighting foam, and fire station dust. While focused on PFAS rather than microplastics directly, the research is relevant because both PFAS and microplastics are persistent environmental pollutants that accumulate in the body. PFAS are also commonly found attached to microplastic surfaces, making microplastics a potential carrier of these carcinogenic chemicals.
Removal of poly- and perfluoroalkyl substances (PFAS) from water by adsorption: Role of PFAS chain length, effect of organic matter and challenges in adsorbent regeneration
Researchers critically reviewed adsorption-based removal of both long- and short-chain PFAS (per- and polyfluoroalkyl substances) from water, concluding that strong anion-exchange resins perform best but that short-chain variants remain especially difficult to remove, and that organic matter effects and adsorbent regeneration are major unresolved challenges for real-world treatment.
PFAS: forever chemicals—persistent, bioaccumulative and mobile. Reviewing the status and the need for their phase out and remediation of contaminated sites
Researchers reviewed the science on PFAS — a large family of synthetic "forever chemicals" used in thousands of products — finding that they persist indefinitely in the environment, accumulate in the food chain, and damage the liver, kidneys, thyroid, and immune system even at very low exposures. The authors conclude that swapping one harmful PFAS for another is not a solution and that a full phase-out in favor of fluorine-free alternatives is necessary.
Why Aim Toward a PFAS-free Future?
This paper is not about microplastics — it reviews the environmental persistence, toxicity, and regulatory challenges associated with per- and polyfluoroalkyl substances (PFAS), the so-called 'forever chemicals,' and argues for transitioning industry toward safer substitutes using green chemistry principles.
Poly- and Perfluoroalkyl Substances (PFAS): Do They Matter to Aquatic Ecosystems?
This review examines PFAS, the persistent 'forever chemicals' widely used in consumer products, and their growing threat to aquatic ecosystems. Evidence indicates that PFAS accumulate in aquatic organisms, disrupt hormones, and can alter how other pollutants behave in the environment. The research is relevant to microplastic concerns because PFAS are commonly found in plastic products and can leach from microplastics into water.
Molecular-Scale Insights into the Interactions between Perfluoroalkyl Substances and Polyethylene
Scientists found that tiny plastic particles called microplastics can strongly attract and hold onto toxic "forever chemicals" called PFAS, which are already found in drinking water and food. This means microplastics in our environment could act like sponges that collect these harmful chemicals and potentially transport them to new places, including into our bodies. The research helps explain why these two types of pollution might work together to create bigger health risks than either one alone.
Fate, distribution, and transport dynamics of Per- and Polyfluoroalkyl Substances (PFASs) in the environment
This review examines how PFAS, often called "forever chemicals," move through water, soil, plants, and air, with their ultra-strong carbon-fluorine bonds making them nearly indestructible in nature. While focused on PFAS rather than microplastics specifically, the two pollutants often co-occur and share similar concerns about persistence, bioaccumulation, and potential health effects.
Environmental behavior of per- and polyfluoroalkyl substances (PFASs) and the potential role of biochar for its remediation: a review
This review summarizes how biochar, a carbon-rich material made from organic waste, can be used to clean up PFAS (per- and polyfluoroalkyl substances), the persistent "forever chemicals" found widely in the environment. Since microplastics can carry and transport PFAS through water systems, understanding how to remove PFAS is an important piece of the broader pollution picture.
Interactions between perfluorinated alkyl substances (PFAS) and microplastics (MPs): Findings from an extensive investigation
This study tested how PFAS ("forever chemicals") interact with 18 different types of microplastic and found that polyamide (nylon) plastics absorbed up to 100% of the PFAS in solution. Since both PFAS and microplastics are widespread environmental pollutants, their ability to bind together means microplastics may act as carriers that concentrate and transport these harmful chemicals into water, soil, and ultimately the human body.
Effect of short-term sample storage and preparatory conditions on losses of 18 per- and polyfluoroalkyl substances (PFAS) to container materials
Researchers tested how 18 types of PFAS "forever chemicals" stuck to common lab container materials and found losses of up to 51% over 7 days, especially for longer-chain PFAS in plastic containers like polypropylene and high-density polyethylene. Adding methanol to samples reduced these losses, with glass and PET containers retaining PFAS most reliably during storage.
Forever Chemicals PFAS Global Impact and Activities, Cascading Consequences of Colossal Systems Failure: Long-Term Health Effects, Food-Systems, Eco-Systems
This comprehensive review examines PFAS (per- and polyfluoroalkyl substances) contamination across food, water, and consumer products, highlighting their interconnection with microplastic pollution. The authors document decades of delayed regulatory action and cover-ups that have contributed to widespread human exposure. Evidence indicates long-term health effects from PFAS exposure, and the review calls for stronger risk assessment tools and policy responses to address this persistent chemical contamination.
Perfluoroalkyl and polyfluoroalkyl substances in sewage sludge: challenges of biological and thermal treatment processes and potential threats to the environment from land disposal
This review summarizes data on PFAS (per- and polyfluoroalkyl substances, also known as 'forever chemicals') found in sewage sludge, which is commonly spread on farmland. Current biological and thermal treatment methods struggle to fully remove these persistent chemicals from sludge. While focused on PFAS rather than microplastics, the findings are relevant because both contaminants accumulate in sludge and enter the food chain when that sludge is applied to agricultural soil.
Interaction of microplastics with perfluoroalkyl and polyfluoroalkyl substances in water: A review of the fate, mechanisms and toxicity
This review examines how microplastics act as carriers for PFAS ("forever chemicals") in water, with the two pollutants interacting through various chemical mechanisms that affect their movement through the environment. The combined presence of microplastics and PFAS raises concerns about increased toxicity, since microplastics can transport these persistent chemicals into organisms and potentially concentrate their harmful effects.
Microplastics as carriers of per- and polyfluoroalkyl substances (PFAS) in aquatic environment: interactions and ecotoxicological effects
Researchers reviewed how microplastics serve as carriers for per- and polyfluoroalkyl substances (PFAS), sometimes called forever chemicals, in aquatic environments. The study found that PFAS can attach to microplastic surfaces and accumulate in organisms through the food chain, potentially amplifying the toxic effects of both pollutants. The findings suggest that the combined presence of microplastics and PFAS poses a greater environmental and health risk than either pollutant alone.
Revisiting the “forever chemicals”, PFOA and PFOS exposure in drinking water
Researchers reviewed 180 years of evidence on PFOA and PFOS — two of the most detected 'forever chemicals' (PFAS) in drinking water — finding that contamination rates increased sharply between 2018 and 2019, and that many developing countries still lack the regulations or technology to address the problem. The review calls for stronger global monitoring systems and improved filtration technologies to protect drinking water supplies.
Critical Evaluation and Meta-Analysis of Ecotoxicological Data on Per- and Polyfluoroalkyl Substances (PFAS) in Freshwater Species
This meta-analysis assessed the toxicity of PFAS ("forever chemicals" commonly found in plastics and coatings) to freshwater species. The findings suggest that even low concentrations of certain PFAS compounds can harm aquatic life, which has implications for ecosystems and the safety of our water supply.
A Review of Treatment Techniques for Short-Chain Perfluoroalkyl Substances
This review evaluates treatment techniques for removing short-chain perfluoroalkyl substances (PFAS) from water, including adsorption, advanced oxidation, and other methods. Researchers found that adsorption was the most widely used and effective approach, capable of handling a broad range of concentrations, though adsorbent regeneration remains a challenge. The study emphasizes the urgent need to improve water treatment technologies as these persistent and mobile chemicals accumulate in the water cycle.
Adsorption of PFAS onto secondary microplastics: A mechanistic study
Researchers studied how PFAS (toxic "forever chemicals") attach to microplastics that form when PET water bottles break down in the environment. They found that PFAS bonds to these microplastic surfaces within hours in both fresh and salt water, meaning microplastics can act as carriers for these harmful chemicals. This is concerning because people may be exposed to both microplastics and the dangerous chemicals hitchhiking on them through contaminated water.
The unheeded inherent connections and overlap between microplastics and poly- and perfluoroalkyl substances: A comprehensive review
This review reveals the overlooked connection between microplastics and PFAS (forever chemicals), showing that these two widespread pollutants often come from the same products and interact in the environment. Microplastics can absorb PFAS onto their surfaces and transport them through water systems, potentially increasing exposure for aquatic organisms and humans. Understanding this overlap is important because the combined effects may be more harmful than either pollutant alone.
Research Progress in Current and Emerging Issues of PFASs’ Global Impact: Long-Term Health Effects and Governance of Food Systems
This review covers per- and polyfluoroalkyl substances (PFAS), commonly called "forever chemicals," which are found in food, cosmetics, drinking water, and are linked to microplastic contamination. Decades of corporate delay and mismanagement have led to widespread human exposure with potential long-term health effects being studied across the globe. The authors examine PFAS levels in food and water from multiple countries and call for stronger regulations to protect public health.
Unveiling the Truth of Interactions between Microplastics and Per- and Polyfluoroalkyl Substances (PFASs) in Wastewater Treatment Plants: Microplastics as a Carrier of PFASs and Beyond
Researchers discovered that microplastics in wastewater treatment plants act as carriers for PFAS (forever chemicals), absorbing them from the water and potentially releasing them back into the environment. Commercial plastics were found to leach even more PFAS than environmental samples, with some chemicals releasing more than was originally absorbed. This dual role of microplastics as both carriers and sources of forever chemicals means they could significantly increase human exposure to these persistent, harmful substances.
Mechanistic Insights into PFAS Adsorption on Microplastics: Effects of Contaminant Properties and Water Chemistry
Researchers investigated how two widely detected PFAS compounds, PFOS and PFOA, adsorb onto five common types of microplastics in aquatic environments. The study found that contaminant properties and water chemistry significantly influence adsorption behavior, confirming that microplastics can serve as carriers for PFAS transport in waterways.
Elucidating governing factors of PFAS removal by polyamide membranes using machine learning and molecular simulations
Researchers used machine learning models to identify the key factors controlling how well polyamide membranes filter out PFAS — the so-called 'forever chemicals' that contaminate drinking water — finding that electrical charge interactions between the chemicals and the membrane are the dominant force. This approach offers a data-driven way to design better water filtration membranes for removing these persistent pollutants.
