Alarming media reports about the harm of microplastics to the human body and the environment are greatly exaggerated, Alexei Khokhlov has told RT

Microplastics are among the most widely discussed environmental topics today. The media often highlights the harmful effects of polymer nanoparticles on living organisms. However, as head of the Department of Polymer and Crystal Physics at Moscow State University, and a member of the Russian Academy of Sciences, Alexei Khokhlov told RT, there is no scientific basis for these claims. Khokhlov argues that microplastic particles are no more hazardous to humans than tiny wood or concrete particles which exist in the environment in much greater quantities.
RT: In recent years, many scientific studies and media reports have been published about microplastics. What exactly are they made of?
Khokhlov: Microplastics are defined as fragments of polymer materials smaller than 5 mm. These particles can break down into even smaller micron-sized pieces, and there are also polymer nanoparticles.
We live in an era dominated by new materials. Just 100 years ago, the polymer industry was virtually nonexistent. The widespread use of plastics began in the 1950s, and today, approximately 400 million tons of various plastics are produced annually worldwide.
