Garbage to Guts: The Slow-Churn of Plastic Waste

People take in up to five grams of MPs a week3– the equivalent of five paper clips– through various routes, turning the human body into its own reservoir of MP waste.4 Researchers discovered MPs flowing through human blood5 and islands of MPs in different organs, including the liver, kidney, spleen, lungs, and placenta.6-10 Humans also excrete MPs in their stool.11 The intestinal (GI) tract is the most common entranceway for MPs, and is an entrance to more widespread systemic dysfunction.
