Detection of microplastics in human saphenous vein tissue using μFTIR: A pilot study

Back to Resource Library

In a small study published in the journal PLOS ONE scientists led by Jeanette M. Rotchell of the Department of Biological and Marine Sciences, University of Hull (UK), found microplastics in tissue samples taken from blood vessels in the legs that help send blood from the legs and feet back up toward the heart (called saphenous veins) in four out of five patients undergoing heart bypass surgery. The scientists observed that the most common plastics found included alkyd resin (which is found in synthetic paint, varnishes, and enamels); polyvinyl acetate (called PVAC, found in adhesives like those used in food packaging and nylon); and ethylene-vinyl alcohol copolymer and ethylene vinyl acetate (called EVOH and EVA, respectively, and are used in flexible plastic packaging). This is the first published research to find microplastics in human vein tissue.
