Be very careful when you handle the burst battery. Cadmium is
*horribly* toxic.

Oh bullshit, Dave. If that were true then anyone who handled cad plated nuts and
bolts would be pushing up daises. Cadmium is barely moderately toxic. An LD50 dose
for rats at 225 mg/kg puts Cd in the mildly toxic range (numbers vary by reporter but
it appears that rats are about 4X more sensitive to Cd than humans). Dealing with a
burst battery doesn't involve any risk of chronic exposure so that doesn't need to be
considered.

Just sweep the thing into the garbage, wipe away the residue with a damp paper towel
and forget about it.

What do you call a blonde's cranial cavity? Vacuum chamber?
hi john , when you state "An LD50 dose for rats at 225 mg/kg" I assume
that means that at that dose 50% of the rats dropped dead .
I am feeling not quite so worried , samuel c.

Yes, when fed cadmium as a soluble compound in one dose. From other data in the
report I took that from, rats seem about 4X as sensitive to Cd as humans. But
assuming that humans and rats respond the same, a 100kg (220 lb) human would require
2.25 grams of the stuff to have a 50% chance of dying from it. That's maybe a level
teaspoon.

Just to put that in perspective, the LD50 dose for aspirin is around 200mg/kg,
depending on the source of the data. The LD50 dose for nicotine is about 55mg/kg. If
our friend Dave is phobic of Cd then he must go nuts in the aspirin row of the local
super and must be out of his mind in the cigs aisle.

I'm firmly convinced that there is a genetic code in most people that causes them to
need to fear things. If we all found ourselves in the Garden of Eden again, I have
no doubt most people would look for the snake....
