This isnt actually the first time microplastics have been found like this, but it will be the first we properly study the effects.

Having talked to a Doctor friend about this he suggests the only safe way to deal with it is to draw blood, to dispose of it, and let the body recover. He had some concern that some of the plastic was as small as blood cells and platelets so might be too hard to filter out. But I guess research will look at that.
