#2 I know lead's not good for little kids, but has there really been a problem with kids using circuit boards for teething rings? And is lead the only harmful thing on them? In fact, if the circuits have lead, and are thus less likely to break, they are more likely to still be installed in functional electrical devices, and teething on THOSE can be seriously and immediately hazardous to ones health.

#3 But EU officials say the regulations banning lead, cadmium, mercury and three other hazardous substances are needed to protect people and the environment.

In other words, it's good when things break. We should all sacrifice for our ~~religion~~ environment.

#4 In light of the fact that we do not yet comprehensively reycle the vastly increasing amounts of consumer electronics, megatons of solder-related lead leaching out of municipal landfills and into our water tables represents a significant health risk. The challenges of unleaded solder interconnections are immense. Unintentionally induced component failures from higher reflow bath temperatures and issues of bond-joint brittleness are not the least among them. Until we use nano-disassembly based reclaimation of all metallurgical assemblies, reduction of lead content will be a pertinent ecological concern.

#5 "But EU officials say the regulations banning lead, cadmium, mercury and three other hazardous substances are needed to protect people and the environment."

what the article doesn't say about the EU is that there is a new EU directive in place that requires manufacturers be resposible for the disposal of their electronic goods at the end of their life. they have to figure out how to retrieve, and then break down / recycle all the bits and pieces to keep them out of the landfills.
