(This is a summary of a Nature Matters Arising article).
I understood that article as there being many bad studies on how much plastics are in our body. But I find it highly unlikely there isn't any plastic in my body, from my toothbrush or chewing gum or water bottle or that old black plastic spatula I fry my eggs with or the air that pushes all kinds of particles into me etc. etc. And studies like your parent comment's https://pmc.ncbi.nlm.nih.gov/articles/PMC12692081/ make it seem likely that they could have some negative effect. So I'm not worried about it, but I also find it a good idea to be cautious (maybe I'll avoid heating food in plastic containers) and for there to be more research into it.
Since that "doubt cast on discovery of microplastics" article there has been the
>Scientists Tracking the Microplastic Pollution Just Realized They Were Measuring Their Own Lab Gloves
thing. Which was quite entertaining. Reminds me of my own abilities as an experimental scientist.
