Blood Cleansing Procedure Removes Microplastics And PFAS Along With CholesterolInternational endocrinologists found that apheresis—a procedure designed to remove excess cholesterol from the blood—simultaneously reduces concentrations of perfluorinated compounds (PFAS) and microplastic particles.

Because PFAS (known as "forever chemicals") and microplastics can bind with plasma proteins and fats, they become "packaged" within lipoproteins. Contamination Risk: Microplastic analysis is highly sensitive to external pollutants; particles could have entered samples from the air or laboratory equipment.
