An interesting study on the effects if lead in the soil was done by Atlanta Agency for Toxic Substances and Disease Registry. Its an interesting paper with alot of hard facts.... Here No "Mays" here either.

Yeah and none of the hard facts (though the paper admits many, many times over that it is not hard facts and is subject to revision) refers to lead contamination from electronic disposal. It refers to lead based paint and leaded gas of yesteryear as the significant contributor of lead exposure to children.

Your example of the Love Canal again does not support the claim about lead in electronics being the big hazard...the Love Canal was a toxic dump of the worst kind and even the papers you cite denote that land fills can be done in a safe manner and that the Love Canal is an example of how NOT to do one.

None of the articles you cite show how a properly run waste management site is going to get lead into drinking water.

If you want to be concerned...please do. The science doesn't back the claim (lead getting into drinking water from old electronics). I have no arguement that lead in humans is harmful and should be be avoided. I have no arguement that lead in children is particularly harmful (more so than in adults).

I have the same view of Mercury too...In fact, I was against mercury fillings long before that was popular and would advise anyone against them. The plastic fillings seem to do as well, look better and don't have the potential negative effects.

If there are lead alternatives that perform as well or better...I'm all for it...until then, I don't see the harm in lead in those applications that don't seem to produce the harm.

Note this view is consistant with my view of cyan tracks versus the applicated ones...the harm just didn't seem to be there to justify the change...the quality is measurably and audibly inferior with cyan to applicated.

I think that driving should be banned. It is a dangurous activity that kills many people every year. Instead of trying to drive safely and enforce the rules of the road we should ban it because it is possible that someone could be killed, even a child! And we cannot allow ourselves to do any that has the potential to harm someone.

The fact that you have to result to name calling

Name calling? I think not...the statements were stupid.

I hear a lot of whining, but you seem to be very short on facts

. Sorry, but no whining on my part...the whining has been from you and all your claims about people/business wanting to hurt children. As to the facts, I have indeed referred to documents on lead in water...none thus far have pointed to old electronics as the source of the problem...all have pointed to such things as lead paint and leaded gasoline (even though it was ceased many years ago it was air born and landed on the tops of most things). It is you sir that have yet to produce any evidence or facts to support your claims.

As to your oil analogy...where is the noisy intermittent? I'll grant you that lack of oil will lead to an intermittent failure and that lead in people will lead to failure...however just as a projector that is properly maintained with oil in the first place will not likely have an intermittent failre so too does the use of lead in electronic products. You have yet to show that the disposal of electronic products with lead in them gets into drinking water. You are trying to prevent a non-existant problem (lead from electronics getting into drinking water). Furthermore, from what I've seen on the lead-free solders, most if not all have the potential to allow illegal levels of toxicity into the drinking water...just not from lead.

So...rather than making your arguement of lead in electronics is getting into the drinking water because you say it is...present your data. The papers I've referened in previous posts and even the ones that Mark referenced pointed to Lead Paint, lead used in plumbing and Leaded Gasoline as the primary sources of lead getting into children, not electronic waste.

The service life of leaded solder and leaded components is pretty well tried and tested. To turn the absurd tables...if you were in an emergency situation in a hospital...would you want that equipment to be any less reliable in the name of lead-free? Just what are the long-term reliability of the lead-free alternatives? What are the environmental consequences of lead-free alternatives? If they are as good or better than the leaded solutions, I'm all for it. I have no stock in the lead industry. Please stop your whining about we are hurting the children because lead is being used in the world...you don't have the facts to back it up.

Anyway...I'm done with this subject and it is WAY WAY off topic and I do apologize to the F-T people for keeping it so far off topic...the moderators should probably move this back and forth over to yak.
