Sorry. I was hungry and couldn't help myself. It was--it was... THE BEAN!

But I have pretzels now, so I'll be okay until the next episode. Thank you for your concern.

Stimmingly yours,
CTBill

I've TRIED to kill it, but you keep reviving it, you little pisher. I must increase my kill count!

Anyway, I predict that it will last longer than my "Brussels Sprouts" thread (don't you DARE revive it), but not as long as the "Canned Neoprene" thread.

Unless we can figure out a way to make wetsuits which bind lead into the primary molecular structure of neoprene--ooohhh... :D

Please do me a favor and dont kill my thread.

A lead wetsuit would be awesome for autistics. but horrible for swimmers.

Strapples I bet you and I are the only ones on this forum who had the super cool experience of wearing a lead suit :)

This is a dumb question, but isn't lead bad? We just had to remove a bunch of stuff from the bookstore I work at because of lead content.

Or is it only bad if you like, lick it or something?

the lead in a lead apron never contacts patient or user. you would need to do some pretty heavy damage to the apron for the lead sheeting to be exposed. and even then they usually coat that in vinyl to act as a second barrier. thus no lead aprons are not bad. but lead its self is.

Mine was given to me when I had an observational opportunity at the Cardiac Catheterization Lab. I was being given a tour of different places in the hospital and spent a few ours inside a little room with monitors. It was really cool to observe. I could not find a matching picture of the lead apron I wore. This is the closest thing to mine Image

IT IS NOT ME IN THE PICTURE i do not look like a model!

lead is bad

1. when you touch lead with bare skin
2. when you drink lead poisoned water

so when water goes through lead pipes, some of the lead dissolves in the water. when you drink water with lead, that poisons you and can make you sick years later. also if you touch lead with bare hands - the lead will rub off on your skin and enter your blood stream. if you do it a little probably nothing will happen. but if you for example handle lead every day at work then yes you could get lead toxicity somewhere down the road.

the ancient Romans had lead pipes. that is why they had so many children with genetic defects.

The toxicity of lead comes from the behaviour of the Pb(2+) ion. This, like the ions of many heavy metals, has a very high affinity for sulphur, and as such tends to bind with the sulphydryl (SH) groups in proteins. This alters the shape of the protein, thus rendering it non-functional. As such, lead will pretty much indiscriminately interfere with biochemical reactions and cause cell deaths when vital enzymes are inactivated. Any source of Pb(2+) will be toxic as a result of this. The only exceptions are highly insoluble compounds like PbS, because it is very difficult for the lead ion to be absorbed by the body. Higher valent lead compounds, such as PbO2 found in car batteries, are also toxic due to the ease with which they are reduced to Pb(2+). As for the metal itself, it is fairly unreactive and not particularly toxic in its own right. However, it will react with weak organic acids (such as those on the skin!), to be converted into Pb(2+), which may then be absorbed into the body. The rate of reaction is slow, but with prolonged exposure to metallic lead toxic quantities of Pb(2+) can easily be created. Incidentally, this tendency of lead to react with weak organic acids was what led to many of the cases of lead poisoning in Rome. It was discovered that when vinegar from wine was left for prolonged periods of time in lead pots, that a sweet tasting substance, known as sapa, was produced. Sapa, also known as sugar of lead, or lead acetate (Pb(CH3COO)2), became very popular as an artificial sweetener, and remained so for hundreds of years. Fortunately, artifical sweeters have come quite some way since then, and it is no longer considered fashionable to sprinkle lead on one's corn flakes.

It is a pleasure to have such an intelligent person on this forum. I'll print out your post for my records. This is just so interesting...

So lead Pb(2+) binds to sulphydryl groups in proteins. I wonder if it affects DNA as well as enzymes, hence genetic malformations in children?
