Rumor has it that Tony Duell may have mentioned these words:

Did a study back in High School (near 15 years ago, so bear with me...) on
PBB (PolyBrominatedBiphenyls) and PCB (PolyChlorinatedBiphenyls) - excuse
the spelling if it ain't perfect - but IIRC PCB's aren't too harmful to you
- until injested. They're fire retardant chemicals, and they got mixed up
with batches of Dairy Feed Supplements at an elevator here in Michigan, USA
back in '75 (again, IIRC).
Moderate to high concentrations *in the body* do bad, bad things,
especially to small children & unborn fetuses (or would that be fetii? ;-)
and it does travel thru cows milk, women's breast milk & the placenta. It
can cause birth defects, miscarriages & serious mental problems, as (once
again, IIRC) it can affect your nervous system in a bad way.
So, if you're not feeding 50 pound bags to your dairy cattle, or serving up
"Capacitor Stew for Two" for you and your pregnant wife, I wouldn't worry
about the toxicity level of any PCB's (should they even exist) in caps.
At least that's what the voices tell me... ;^>

Recycling is good, right??? Ok, so I'll recycle an old .sig.
If at first you don't succeed, nuclear warhead
disarmament should *not* be your first career choice.
