BPA-poisoning from receipt paper #cancer

2.1: news.health/BPA-poisoning from receipt paper:
. shopping reciepts use a type of paper
that is impregnated with BPA (Bisphenol-A)
an endocrine disruptor linked to cancer,
obesity, diabetes, CVD, and infertility .
. how much of the BPA rubs off on your hands
depends on what else is on your hands:
. using hand sanitizer (and other skin products
that contain dermal penetration enhancers)
increases BPA absorption by as much as 185 times
[chriskresser].

The default method used by regulatory agencies
to test for hazards posed by chemicals
is intra-gastric gavage. For BPA
this approach results in less than 1% of
the administered dose being bioavailable in blood.
It also ignores dermal absorption as well as
sublingual absorption in the mouth
that both bypass first-pass liver metabolism.
The elevated levels of BPA that we observed
due to holding thermal paper after using a product
containing dermal penetration enhancing chemicals
have been related to an increased risk
for a wide range of developmental abnormalities
as well as diseases in adults [plos.org 2014].
