This location suggests that tiny bits of plastic could get into the brain if they're in the air we breathe.

The autopsies identified 16 different plastic particles or fibers.

The researchers note that nanoplastics, particles that are even smaller and harder to detect,

Another way plastic compounds get into our body is through food packaging.
