Flame retardants from TVs ending up in recycled plastic being used for food storage, etc, etc.

It's a jungle out there and if not unregulated, then very much un-policed. PFAS was seen as completely benign for decades, turns it isn't and that is bio-accumulates.

Specific chemicals like BPA being banned in certain applications, only to be replaced by some other, very similar chemical, which then legislators play whack-a-mole with (or whack-a-sloth) very slowly, over decades.

Plus imports from China. (And some other countries, but hey, China has the volume. Shouldn't they care even just a little themselves too?)

Heck, toys from there still sometimes contain lead, which should really not be a thing in this day and age, but the fact that it sometimes still happen should indicate how little the producers and importers know or care.
