Microplastics In Human Blood

Microplastics In human blood:

A study by researchers from The Netherlands found the presence of Microplastics in human blood.

  • Microplastics are tiny bits of various types of plastic found in the environment.
  • The name is used to differentiate them from “macroplastics” such as bottles and bags made of plastic.
  • There is no universal agreement on the size that fits this bill — the U.S. NOAA (National Oceanic and Atmospheric Administration) and the European Chemical Agency define microplastic as less than 5mm in length.
  • However, for the purposes of this study, since the authors were interested in measuring the quantities of plastic that can cross the membranes and diffuse into the body via the blood stream, the authors have an upper limit on the size of the particles as 0.0007 millimetre.
  • The study looked at the most commonly used plastic polymers.
  • These were polyethylene tetraphthalate (PET), polyethylene (used in making plastic carry bags), polymers of styrene (used in food packaging), poly (methyl methylacrylate) and poly propylene. They found a presence of the first four types.
