ClearPoly- 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.
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.
Microplastics and PFAS air-water interaction and deposition
This study examines how microplastics and PFAS (forever chemicals) interact in the environment, with microplastics acting as carriers that transport PFAS through water and air over long distances. Both pollutants are persistent and can deposit together in urban, rural, and remote areas through rain and atmospheric fallout. The combined exposure to both microplastics and PFAS is a growing concern for human health because their toxic effects may be amplified when they occur together.
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.
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.
Effects of perfluoroalkyl and polyfluoroalkyl substances on soil structure and function
This review examines how PFAS (per- and polyfluoroalkyl substances) — often called forever chemicals — affect soil structure and the microbial communities that drive nutrient cycling. PFAS are found in many plastic-associated products and coatings and persist in soils for decades. The authors identify significant gaps in understanding how PFAS concentrations found in real-world soils affect ecosystem health.
Analysis and fate of per- and polyfluoroalkyl substances (PFAS) in the global aquatic environment: perspectives and combined risks with microplastics
This review provided a comprehensive overview of PFAS fate, transport, and toxicity in global aquatic environments, with particular attention to analytical challenges for ultrashort-chain compounds. The authors also addressed combined risks from PFAS and microplastics co-occurring in water, noting synergistic contamination concerns.
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.
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.
Review 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.
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.
A review on per- and polyfluorinated alkyl substances (PFASs) in microplastic and food-contact materials
Per- and polyfluorinated alkyl substances (PFAS) used as oil- and water-repellent coatings on food contact materials can migrate into food, and microplastics in aquatic environments can sorb and transport PFAS, though desorption processes remain poorly understood.
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.
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.
From co-occurrence to co-existence and co-exposure: Associations between per- and polyfluoroalkyl substances and microplastics in the environment
This review examines the growing recognition that PFAS chemicals and microplastics frequently co-occur in the environment and may interact in ways that affect both ecological and human health. Researchers identified four major sources that emit both pollutants simultaneously and found strong evidence that PFAS can adsorb onto microplastic surfaces and be co-transported through the environment. The study calls for standardized methods and long-term studies to better understand the combined exposure risks of these two widespread contaminant classes.
PFAS Associated with Microplastics (MPs)
This review examined the environmental and health risks of the 'forever alliance' between PFAS and microplastics, where PFAS adsorb onto MP surfaces, increasing their environmental mobility, bioavailability, and combined toxicity. The interaction amplifies the hazards of both contaminant classes and complicates risk assessment.
Co-accumulation characteristics and interaction mechanism of microplastics and PFASs in a large shallow lake
Researchers examined how microplastics and per- and polyfluoroalkyl substances, commonly known as forever chemicals, accumulate together in Taihu Lake, China. They found that microplastics can adsorb and concentrate these persistent chemicals on their surfaces, with the interaction strength depending on plastic type and environmental conditions. The study raises concerns that microplastics may act as carriers that spread forever chemicals through freshwater ecosystems.
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.
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.
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.
Global Perspective on the Impact of Plastic Waste as a Source of Microplastics and Per- and Polyfluoroalkyl Substances in the Environment
This perspective examines the global environmental impact of plastic waste as a combined source of both microplastics and per- and polyfluoroalkyl substances, commonly known as PFAS or forever chemicals. Researchers highlight how plastics can release or transport these persistent chemicals as they degrade in the environment. The study argues that addressing plastic pollution requires considering these interconnected contaminants together rather than treating them as separate problems.
Impact of per- and polyfluorinated alkyl substances (PFAS) on the marine environment: Raising awareness, challenges, legislation, and mitigation approaches under the One Health concept
This review examines how PFAS (per- and polyfluorinated alkyl substances), often called 'forever chemicals,' are contaminating marine environments and interacting with other pollutants including microplastics. PFAS accumulate in marine food chains and can combine with microplastics to amplify toxic effects on ocean wildlife and ultimately human health through seafood consumption. The authors call for stronger regulations and cleanup strategies under a One Health approach that connects ocean, animal, and human well-being.
Interactions between MPs and PFASs in aquatic environments: A dual-character situation
This review examines the interactions between microplastics and per- and polyfluoroalkyl substances (PFAS) in water environments, finding that the two pollutants have a complex relationship. Microplastics can absorb PFAS chemicals onto their surfaces, potentially transporting them through aquatic systems and altering their environmental behavior. The study highlights the need to consider these combined effects when assessing pollution risks in waterways.
