Tuesday, May 20, 2025

Microbiologist Jacques Robert, PhD, told The New York Times (May 20) that his research shows tadpoles excreted about 60 percent to 70 percent of the microplastics they were fed. His studies also suggest that microplastics may weaken the immune system. While animal studies don’t always translate directly to humans, other research indicates that microplastics not excreted can enter the bloodstream and migrate to organs like the liver and brain.
