There's a huge range of possibilities between arsenic and "minor harm."

We have decent reason to believe they are active in the endocrine system, and pretty good reason to believe there are population-level endocrine issues (obesity and fertility).

Given that these plastics seem to accrue intergenerationally (i.e. babies are being born "poisoned" by them), an apparently minor, apparently not-very-acute issue could actually end up being a much, much, much bigger problem than any of the examples you listed.
