I hate to doubt studies, but with advice like: "Invest in a zippered fabric bag and ask the dry cleaner to return your clothes in that instead of those thin sheets of plastic." I am doubtful. I assert that the number one source of microplastics in a house will be clothing. Your "lint trap" in a dryer? Largely microplastics.

Dust in your house? Again, largely made up of fabric fibers. Which are increasingly plastics. Especially so if you have a carpeted house.

I'm not fully against some of these ideas and studies. And I am all for reducing our exposure to microplastics, where we can. But folks largely ignore the microplastic lining in cans, thinking they are avoiding that plastic bottle. We seem to have done a great job of avoiding large plastics in the fear of microplastics. Meanwhile, folks have very little intuition on where the microplastics come from.
