If there are negative reports reportedly caused from microplastics there will be resources looking into the subject matter. Studies that look at the long term effects will take time, but there might be some shorter length studies comparing different plastics and their effects at poisonous dosages. I know that companies claim that their products are “BPA Free” maybe that’s a good starting point for your research. (I don’t know the reason why everything is BPA free, but it must’ve been big enough to leave a digital footprint.)
This is a reliable explainer for it https://www.food.gov.uk/safety-hygiene/bpa-in-plastic (tldr: less than 0.2µg is considered safe daily dosage per kg of body weight. BPA is used to make plastics rigid, but can be disruptive to the endocrine system if too much is absorbed into the body.) (Now I know why plastics are called BPA free now. But if they’re not using BPA what are they using?)
Either the studies will tell us how much, or until we feel the negative effects from the dosage of plastics.
We don’t know how clear it will be before there are negative effects. It could be alarming amounts. Ever see a smokers lung?

All I know about BPA is the chemical process to create polymers from it is quite toxic and those chemicals never really go away.
