"Microplastics have been found in human stool samples from countries in many parts of the world, according to a small pilot study being presented this week at the 26th annual United European Gastroenterology conference in Vienna.

The study, conducted by researchers from the Medical University of Vienna and the Environment Agency Austria, looked at stool samples from eight individuals in eight different countries: Finland, Italy, Japan, the Netherlands, Poland, Russia, the U.K. and Austria. Every stool sample tested positive for up to nine different plastic types, with an average of 20 particles of plastic per 10 grams of stool.

'Personally, I did not expect that each sample would ... [test] ... positive,' says lead researcher Dr. Philipp Schwabl of the Medical University of Vienna. He and his colleagues found that all eight stool samples contained polypropylene and polyethylene-terephthalate particles, which are major components of plastic bottle caps and plastic bottles. 'Is it harmful to human health? That's a very important question and we are planning further investigations.'"
