It isn't enough to say we're seeing something in blood and fetuses, it has to be quantified by how it is a problem.

I find alcohol in my blood all the time, I understand the effects and manage it so it's never a problem. Alcohol in fetuses on the other hand is a well understood problem where no level is really tolerable.

So, back to plastics. I found https://earth.org/how-does-plastic-pollution-affect-humans/ offers some indication. But I would love to see better information from a non-biased source. I've a suspicion that earth.org is biased.

From the linked article, plastics are a problem but the pollution level is probably below the threshold of harm for most people. But it's also possible that the levels have increased over the past couple of years to the point that it is harmful.
