> Everything that goes into our bodies gets filtered through our livers and kidneys, so maybe it’s not a big surprise that bits of plastic find their way into those organs. Same with our hearts; microplastics end up in our blood and can get stuck in our clogged arteries.

> But our brains are designed to keep things out ... researchers behind the brain plastics study think the tiny shards of plastic hitch a ride on fat molecules to get [past the blood-brain barrier] inside brain cells ... The researchers estimated that the average brain studied had about seven grams of microplastics in it.

Having 7g of _anything_ foreign inside my brain seems like cause for concern to me.
