https://medium.com/p/2587fc2d6932 In a recent study conducted by researchers from the University of Campania Luigi Vanvitelli in Italy, a surprising discovery was made: microplastics were found within arterial plaques. These tiny plastic particles, measuring less than 5 millimeters in length, were present in approximately 60% of the plaques removed from patients with atherosclerosis
I don't have a study for you, but the logical conclusion is yes.

Quick search says we use pvc plastics for most blood bags...gonna go sit and silently rock myself in a corner while I process this newfound potential horror.
If possible I'd recommend skipping ahead to acceptance, it's a bit less angsty over here.
Alas, my neurodivergent brain doesn't process things normally. Glad my hyperbole got a quick label though.
