You stir the pot! The EU have never done either a risk assessment or an
environmental balance sheet. It is pure whim based on lead being a dirty
word, with unscientific pressure groups lobbying (and some commercial
jumping on the bandwagon). There are many members on this forum who will
support me on these contentions. All post mortem studies have shown this
to be the case, so it is purely a political issue.

As for your 40% of all lead in landfills being from electronics, I'm
afraid this is nonsense. This would imply that ALL lead in landfills is
contained in solder. A single car battery would be equivalent to
hundreds of PCs, but one CRT monitor or TV set would have as much lead
in the glass as more hundreds of PCs, but this is not the subject of the
restrictions.

This is a very complex and controversial subject and, if you wish to do
it justice, you will need more than a page or two in a book.
