Schwabl P, Köppel S, Königshofer P, et al. - Through a prospective case series done in Europe and Asia, in which individuals (n = 18; aged 33 to 65 years) finished a food diary and sampled stool according to step-by-step instructions, researchers investigated human feces for the presence of microplastics in order to ascertain whether humans, not knowingly, ingest them. All eight stool samples had positive test results for microplastics. Per 10 g of human stool, a median of 20 microplastics (50 to 500 µm in size) were recognized. In all, nine types of plastic were identified, of which polypropylene and polyethylene terephthalate was the most plentiful. Hence, different microplastics identified in human stool implies that there is inadvertent ingestion from various sources. Furthermore, additional research is required on the magnitude of microplastic consumption and the potential impact on human health.
