I wonder just how much of a problem lead bearing solder used in
electronic devices is ...
Tin and lead is a stable compound, and the lead does not wash out of it in
water. Pure lead is not soluble in water.
Not in pure water, maybe, but organic acids (acetic acid) attack lead
and you can't have decomposition of organics in contact with lead in a landfill,
without some leaching.
