Many of these microplastic studies [1-9] rely on small sample sizes (e.g., n=10 for brain tissue) and detection methods that could pick up contamination from lab equipment itself. It reminds me of when everyone was afraid of BPA
And what defines a “microplastic”? There’s so many different types of plastics that all have different effects on the body
What’s really the health trade-off compared to having to monitor every tiny little thing
You can definitely ignore them if you think that ignoring them and putting work elsewhere is a net benefit to everyone. Not every action merits a response.
There’s also no clear definition of microplastics that I’ve seen. Different plastics have different toxicitiy
