Numbers I've got are for year 2002 :
Pb : 2,800,000,000 Kg
Lead in electronics : 14,150,000 Kg
Pareto is :
Storage batteries : 80,81%
Oxides (paint, glass, ceramic, chemicals): 4,78%
Ammunition, shot and bullets : 4,69%
Sheet lead : 1,79%
Cable covering : 1,14%
Casting material : 1,13%
Brass & Bronze : 0,72%
Pipes, traps, other extrusions : 0,72%
Solder (non-electronic) : 0,7%
Solder in electronics & CRTs : 0,49%
Miscellaneous : 2,77%
Another number I've got, gives 30% of the Pb leachages in landfills are due
to the 0,5% of Pb in electronics.

Subject: [LF] amount of lead comsumed
Hi All,
We all know that electronic solder consumes only 0.49% of the total lead
consumption. Looks like a very low value, but is there a number (in Kg or
pounds) which gives the total amount of 'lead' this 0.49% consumes? I guess
it will be a big enough number to console that moving to lead-free is
reasonable. I would greatly appreciate if an authentic source is available.
Thank you Sincerely Santhakumar
