Episode notes
Microplastics Widespread in Humans
- Microplastics are found in almost every human organ including the brain, reproductive organs, and placentas.
- Their amount in brains has risen 50% from 2016 to 2024, equaling about 7 grams per brain.
Microplastics in Placentas Linked to Births
- Microplastics have been found in placentas, with higher amounts in preterm births.
- This suggests possible delivery from mother to fetus, raising concerns about child development.
Diet Major Source of Testes Plastics
- Microplastics are present in human testes, with three times more plastics found than in dogs' testes.
- This suggests diet may be a major microplastic source rather than environmental contact.
