Yep, the science is in. Lead, asbestos, DDT, PCBs, and PTFE/PFOS/PFOA.
3M Scotchgard (spray-on water-repellent for materials) was mostly PFOS, now it's PFBS.
Hipora, OTOH, is silicon-based. SympaTex is polyester-based.
On another note: I felt extremely stupid paying $300 for a Columbia Elite running rain jacket with Gore-Tex, with a lifetime warranty and bought from their store in Seattle, that subsequently disintegrated into god-knows-what and they wouldn't honor it. Never again: Gore-Tex or Columbia.
Comparison table of water-resistance and breathability of water-resistant fabrics:
