33) Pb - toxic heavy metal ,
neurotoxin ,
- found in
older paints, car batteries,
electronics,
(was in leaded
fuel) , older plumbing, soil around lead smelters ,
Only women who can prove they are
sterile can seek work in the lead industry processing areas. The reason
being that fetal damage can occur at maternal blood lead levels of 25 µg/dL
and fetal growth retardation begins at maternal blood lead levels of 8
µg/dL.
- low levels in children can cause learning impairment
34) Rn - daughter product of the 235U decay
- this gas leaks up through cracks in rocks + basements
- considered a major problem in
the USA but not in Canada !???!
35) 235U - fuel stock for CANDU
nuclear reactors and atomic bombs (fission)
- depleted uranium is used to make hardened tips on
American
missile tips for piercing tanks

- To date the only depleted uranium (DU) weapons acknowledged by the US
and UK governments have been anti-tank munitions - mainly 30 mm and 120 mm DU penetrators - and 20 mm Phallanx sea-to-air shells. In the Gulf war
some 300 tons of DU anti-armor munitions were declared and in the Balkans
war just under 10 tons.

36) 244 Pu -
plutonium is probably
the most toxic element on earth capable of causing cancers in very small
amounts
- used to make atomic weapons and to fuel fast breeder nuclear reactors
- by product of
uranium nuclear reactors (waste)
