If you read the article you'd find that what they are finding are not microplastics - they're stearates[1] These are soap-like chemicals used as mould release agents on gloves, but what also means are chemically similar to plastics when analyzed by some techniques and under a microscope will spontaneously form micelle-structures which look very similar to microplastics (you can't exactly get in there and poke them).
