Plastics in our body

Only fairly recently we have become aware of the dangers of plastics in our environment.
For a long time we thought these plastics would not be of any concern to us. However, invariably, most plastics end up somewhere in the environment: they sit at the bottom of the sea, mix into beach sand, and blow in the wind. They’re also inside us.

It's possible that humans may be consuming anywhere from 39 to 52 thousand microplastic particles a year. With added estimates of how much microplastic might be inhaled, that number is more than 74 thousand.
People who drink only bottled water ingest an additional 90 thousand particles.

When researchers from Johns Hopkins looked at the impact of eating seafood contaminated with microplastics, they too found the accumulated plastic could damage the immune system and upset a gut's balance.

Scientists are scrambling to understand the dose at which microplastics start to have noticeable health effects. Like air pollution or harmful construction materials, those who have more exposure or pre-existing conditions may be less able to tolerate plastic.
