\" \" Some study subjects' fecal stool samples contained as many as nine different types of microplastics, with polypropylene (PP) and polyethylene terephthalate (PET) being most common. All eight of the subjects turned out to have microplastic in their poop — on average, 20 particles per 0.35274 ounces (10 grams) of feces. The records showed that six of the eight ate seafood, and all either consumed food that had been wrapped in plastic or else drank from plastic bottles. There is now so much plastic in the environment \"that the exposure is almost ubiquitous,\" he adds. Those include the synthetic textiles that often cover our bodies, as well as carpeting and plastic items in our indoor surroundings.
