People inhale more microplastics from breathing than they ingest from food and drink.
"you actually get more microplastics from breathing than what you do ingestion." (said at 1:02:22)
No published record matching the claim that people inhale more microplastics from breathing than they ingest from food and drink was located; this does not prove the claim false.
corroborated by web sources
Environmental health studies and scientific reviews estimate that people often inhale more microplastic particles from indoor and ambient air than they consume through food and beverages. Research assessing human microplastic exposure identifies inhalation—particularly from airborne synthetic fibers and indoor dust—as a primary exposure pathway that frequently exceeds dietary ingestion.
