Ironically, I was reading an article in National Geographic about atmospheric
carbon at my physical therapist while getting a Anodyne therapy treatment on
my feet (I may have Peripheral Nueropathy, but I digress...). The article is
very interesting! Go to:
http://magma.nationalgeographic.com/ngm/0402/feature5/
It's called; "The Case of the Missing Carbon"...maybe it's on the pins?
-Steve Gregory-
It is worth considering that electroplated Tin uses organic (meaning
containing Carbon) addition agents (brighteners) which are co-deposited with
the
Tin....
and having NO evidence one way or another, I would put a fair amount, with
very attractive odds, on the fact that this is a MUCH more likely source of
Carbon, than atmospheric anything.
