Microplastics found in human blood vessels may come not from the body itself, but from contamination during medical procedures or lab testing, particularly from particles in the air or chemicals...
Mechanism
Synthesis from 1 study
Plastic bits from gloves or the air in hospitals and labs can get onto surgical tools or tissue samples, making it look like plastic is inside blood vessels when it actually came from outside the body. This means what scientists think they're finding might just be contamination from the equipment...
Most probable mechanism
Tiny plastic fragments from gloves or airborne particles in operating rooms and labs can stick to tools or surfaces, then get transferred into blood vessels during surgery or sample handling, making it look like plastic is inside the body when it actually came from outside.
Plastic particles are released from synthetic materials such as gloves, surgical drapes, or cleaning agents through physical abrasion or chemical leaching during handling or sterilization.
These released particles become airborne or adhere to instruments and surfaces in clinical and laboratory environments.
During surgical procedures or tissue processing, the particles are physically transferred onto or into vascular tissue through direct contact with contaminated tools, gloves, or airflow.
The particles remain embedded in the tissue matrix and are later detected using microscopy or spectroscopy, mistaken for endogenous microplastics.
