Wolf-Dieter:
Your computation shouldn't need any further comment, but I suspect you will encounter plenty
of denunciation nonetheless. Solder lead (and component lead) is not an environmental problem.
(And Erik de Kluizenaar has been waging a passionate and eloquent battle for pragmatic
recycling that would take care of the whole nasty business.) When the failure rate of critical
electronic assemblies rockets because of overheating components, I expect mass changes of
minds. But it will be too late then, won't it?
