Episode notes
Microplastics: A New Pollutant
- Microplastics, a relatively recent concern, are contaminating the entire planet and its organisms.
- The term "microplastic" wasn't coined until 2004, highlighting the recency of this research.
Microplastics vs. Nanoplastics
- Macroplastics break down into microplastics (smaller than 5mm) and then nanoplastics (around a millionth of a meter).
- Nanoplastics are concerning as they can enter individual cells, posing a significant health risk.
Microplastic Consumption
- Ingesting microplastics through seafood is a concern, especially with filter feeders like mussels and clams.
- However, inhaling microplastics from indoor air is a larger source of contamination, estimated at 7,000 particles daily.
