The ROHS rationale was to protect the health of folks doing
recycling.


That's only part of it. It's supposedly true that rain (and other
solvents)
leech lead from electronic equipment, and it winds up in drinking
water.


Therein lies an example of why we have the RoHS BS.


But lead was mined out of the ground in the first place!


But not much of the drinking water comes from where its mined.


Not that I think it makes any sense at all to ban lead in solder.


Much drinking water in the UK was, and continues to be, supplied via lead
pipes, and not all areas have 'hard' water supplies that coat the inside
of those pipes with a 'protective' limescale layer.


Yebbut, some have blamed the decline of the
roman empire on their use of lead plumbing pipes.



Making their dinner plates out of pewter probably didn't help - usually at
least 80% tin it contained lead & antimony amongst other things.
