The study questioned how microplastics could impact the heart, and found that these tiny plastic particles, mostly invisible nanoparticles, were in the artery plaque of study participants.
The researchers analysed 257 people who had surgery to clear blocked vessels, looking at the fatty build-up in their carotid arteries which supply blood to the brain, face, and neck. Using two methods, they found evidence of nano-plastics in the plaque of 150 patients, with no evidence of plastics in some 107 patients.

What really worries me is that it is impossible to remove the mind-boggling amounts of micro- and nano-plastics from the world at large, and more and more particles continue being added as plastic already there breaks down further and further into smaller and smaller pieces. Removing the larger plastic we can see is vital, as is the reduction of plastic pollution worldwide in any way we can reduce it. But whatever we do, we are stuck with the plastic problem and have no way of knowing how humans or wildlife will react in the long term. The world is currently a laboratory where the effects of plastic pollution are being studied, but often not studied too. In many places like the depths of the oceans it is exceedingly difficult to find out what is happening. I think about the deep-sea life, most of which is adapted to a shortage of food, now has plastic added to the menu. And plastic is in the food-chains because tiny creatures are consuming it. Plankton contains nano-plastic. I wrote a song asking "Where Does All The Plastic Go?"
