PlasticList is amazing and thank your raising these issues, it never crossed my mind and I use this everyday!
That linked StackExchange thread perfectly portrays why the site went down the drain.
>Maybe you'll ingest more microplastic on fish or proteins in higher food chain than grinders.
>If you drink tea you've got a lot more to worry about in terms of ingestion.
OK ... ?
>Your concern, although logically valid, is nearly impossible to regulate or even measure.
And yet, PlasticList is a thing.
>We're talking about amount that is, literally, microscopic.
Yeah Einstein, that's why they're called microplastics.
I am SO glad that place is extinct now.
