Let's be clear that the United States has less stringent
regulations. AIUI, commercial (as opposed to consumer) boards for
sale in the U.S. may still use leaded solder.

Hmm.. I didn't realize that there were any regulations on leaded
solder here
in the USA. I just thought we got consumer grade crap that was
manufactured
for sale in the EU that happens to be ROHS compliant.

Ditto. I'd love to know about any laws banning leaded solder in the
USA so I can get a jump on starting my new multimillion-dollar
recycled home- electronics business.

For residential plumbing, lead solder has been illegal in the US since
1988 or so.

Well there is lead solder in my house and I drink the water. No lead
poisoning yet..

Many old houses over here still have lead pipework feeding them with
water. Certainly, the house that I lived in and drank the water in for
many years as a kid, had lead pipes. Leaded solder was banned here some
years ago for 'open' pipework systems, but as far as I know, there was
no such restriction for 'closed' systems such as central heating. Lead
is not soluble in water anyway,

Under normal conditions lead does not react with water. However, when lead
comes in contact with moist air reactivity with water increases. A small
lead oxide (PbO) layer forms at the surface of the metal. When both oxygen
and water are present, metallic lead is converted to lead hydroxide (Pb(OH)
