This is a Chemistry question:
>can you synthesize xenoestrogenic molecules (like ethinylestradiol) out of any polymer (i.e. polyethylene)?

>why the hell scientists have detected estradiol in bottled water?

Since estrogens are polycyclic compounds I wonder how it could be generated from linear hydrocarbons like PET
