So yes, microplastics are probably in you. But don’t fret just yet. When we think about any kind of pollutant in the body, we need to consider several things. Firstly, there is the question of size, and for microplastics, there is a huge range. Then there’s what dosage would show any effect. And finally, whether that effect is actually harmful. As many of the studies involve animals, we also need to ask whether those animal studies can reasonably apply to the average human.
