PFAS vs. Microplastics: What Makes Them Different and Why It Matters
Recently, there has been growing discussion about two important environmental pollutants - PFAS and microplastics. Although both are part of our environment, they pose significant health risks to humans and ecosystems. Microplastics and PFAS are not the same. PFAS are chemicals used in everyday items such as waterproof coats and non-stick cookware to make them water and heat resistant.
Microplastics, on the other hand, are tiny plastic fragments formed when larger plastic objects break down. Despite being different types of pollutants, each can harm the environment. This blog explains the differences between PFAS and microplastics and why understanding them is important.
What are PFAS?
PFAS (per- and polyfluoroalkyl substances) are a group of synthetic chemicals found in many consumer and industrial products. They are known for their ability to repel water, resist grease, and prevent sticking. Due to their durability and resistance to breaking down, PFAS are often called "forever chemicals." Common PFAS compounds include perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS).
PFAS are used in products like firefighting foams, food packaging, waterproof clothing, and more. They are resistant to natural degradation.
What are Microplastics?
Microplastics are very small plastic particles (less than 5 millimetres in size) that come from the breakdown of larger plastics or are produced directly. These particles are found everywhere, in oceans, rivers, soil, and even the air, and can persist for centuries because they do not dissolve in water.
The main sources of microplastics are the degradation of larger plastic items and the use of specific products that contain microplastics. Microplastics can float or sink depending on their density.
PFAS vs. Microplastics: Key Differences
The main differences between PFAS and microplastics lie in their nature and behaviour.
Chemical vs. Physical: Microplastics are solid particles, while PFAS are dissolved chemicals.
Solubility: Microplastics remain as visible or microscopic solids that float or sink; PFAS can dissolve in water and migrate through groundwater.
Health and Environmental Impact: Microplastics can cause physical harm or blockages in animals' digestive systems. PFAS can accumulate at the molecular level, contaminating blood and tissues, which may lead to developmental issues in children and cancer.
Why Does the Difference Matter?
Understanding the differences helps in research, regulation, and cleanup efforts. PFAS requires chemical treatment methods such as adsorption, ion exchange, or enhanced filtration to remove dissolved pollutants. Microplastics are managed through physical techniques like fine filtration, sedimentation, or source reduction.
Implications for PFAS Cleanup
PFAS are chemical pollutants needing specialised treatment. Using solutions like Granular Activated Carbon (GAC) and Powdered Activated Carbon (PAC) from Bygen provides effective adsorption for PFAS in soil and water. These porous carbons trap PFAS, preventing their spread into ecosystems and drinking water.
Bygen’s Role in Combating PFAS Pollution
Bygen offers sustainable solutions for PFAS contamination using activated carbon technology. Bygen’s approach reduces environmental impact through low-emission and circular production processes.
Bygen’s PFAS Clear Pilot Program is designed to eliminate PFAS chemicals by collaborating with industries and municipalities, establishing Bygen as a trusted partner in creating chemical-free environments.
Conclusion
Understanding the difference between PFAS and microplastics is essential. Unlike microplastics, which are durable particles, PFAS are persistent chemicals.
Both pose risks, but each requires different approaches for management. For more details on the differences and how Bygen's PFAS Clear program can help, contact us here.
