 Microplastics are something that I've been talking a lot about with my team lately. Plastics in general are a relatively new introduction to society, and scientists are now just starting to understand the impact they can have on human health. Take for example this new study out of Italy. It found that people with microplastics or nanoplastics in their carotid arteries were twice as likely to have a stroke, a heart attack, or die from any cause.
