Microplastics Found In Human Blood For First Time, The Guardian, 24 March 2022
Microplastic pollution has been detected in human blood for the first time, with scientists finding the tiny particles in almost 80% of the people tested.
The discovery shows the particles can travel around the body and may lodge in organs.
“It is certainly reasonable to be concerned,” Vethaak told the Guardian. “The particles are there and are transported throughout the body.” He said previous work had shown that microplastics were 10 times higher in the faeces of babies compared with adults and that babies fed with plastic bottles are swallowing millions of microplastic particles a day.
“Plastic production is set to double by 2040,” said Jo Royle, founder of the charity Common Seas.
A recent study found that microplastics can latch on to the outer membranes of red blood cells and may limit their ability to transport oxygen. The particles have also been found in the placentas of pregnant women, and in pregnant rats they pass rapidly through the lungs into the hearts, brains and other organs of the foetuses.
A new review paper published on Tuesday, co-authored by Vethaak, assessed cancer risk and concluded: “More detailed research on how micro- and nano-plastics affect the structures and processes of the human body, and whether and how they can transform cells and induce carcinogenesis, is urgently needed, particularly in light of the exponential increase in plastic production. The problem is becoming more urgent with each day.”
We should stop producing plastics. “Once the plastic is in the environment, we can’t really get it out.”
