>>10881788There's a decent study on ACS publications with several dozen citations that studies ABS microplastic toxicity. The study concluded that ABS and PVC are not at risk for hemolysis as they do not penetrate the walls of red-blood cells. However, a major limitation of the study was that with an incubation time of only 5 days, it may not have been enough time to allow for plasticizers to leak into the blood stream. TL;DR: It's probably fine unless you have an abnormally high and repeated exposure.
