Microplastic Exposure: Seafood Not the Main Source
According to new research, people are more likely to ingest microplastics from bottled water and indoor air than from eating seafood.
A study published in Environmental Science & Technology Letters, led by Ted Henry, professor at Heriot-Watt University, found that seafood contributes only 1–10 microplastic particles per day to the human diet, comparable to other foods like chicken.
- Bottled water may contain 10–100 microplastic particles daily.
- Indoor air exposure can reach 100–1,000 microplastic particles a day.
More than 70% of scientific and media reports on microplastics in food have focused on seafood.
Author's summary: Seafood is not a major source of microplastic exposure.
