It slowly builds up in the body, and then causes health problems. I think I covered it in some links here. But that is a very good question by the way.

Hi, I have a question. If you cook something on the plate in the microwave, then would the microwave kill the lead in the paint or make it more potent or do anything at all one way or another?? Does anyone know?

IngentaConnect Effect of microwave heating on leaching of lead from old ceramic ...

About microwaving and lead. Only problem is in order to read this article you have to subscribe to the magazine or whatever it is.

This one below is just another article on the California law on lead:

California Childhood Lead Poisoning Prevention Branch

Only thing I could find is that microwaving food in lead dishes causes the lead to leach out more. Storing food in lead containers does the same.

Good morning, jessaka and Unite

Jessaka:

I’m afraid that you have mischaracterized my statement, and I never stated that it is “harmless to use dishes with lead in them.”

My post was very clear, in that I made the statement that the mere presence of lead in the item does not necessarily speak to the issue of whether or not it poses an hazard, since the lead may or may not be bioavailable. If the lead is not bioavailable, such as the case in fine leaded crystal (and many other items), then there is no hazard.

I have tested may different household items for lead, (total lead), and speciated that lead (which speaks to the issue of it’s availability).

In reading my posts, the devil is in the details; miss the details, and you will miss the meaning of the post.

Unite:
I have not read the links provided to you, however, microwaving the item will do nothing to the lead content, or the availability of the lead in the item. Lead is a naturally occurring element that cannot be altered or changed, (except by radioactive decay or transmutation, which is beyond the scope of this post).

Jessaka is not quite accurate in her comment that microwaving food causes greater leaching from leaded items, to the extent that it is not the microwaves that are increasing the leaching, but rather it is the fact that the material (if the lead is available at all) is being heated. (This is not a personal put down, jessaka, it is simply the truth). Heat two identical items one in a microwave oven, and the other heated in a conventional convection oven, with the same material, and will both exhibit the same degree of leaching.

By the way, I have performed a number of such leaching teaching tests, wherein I have taken the cooking items and placed fruit juices and even strong acetic acid, in the items and compared the leachates for lead content. Usually I would determine total lead by x-ray fluorescence, and the leached lead by atomic absorption spectrophotometry; the ratio between the two speaks to the “leachability” but not necessarily to the bioavailability of the lead in the leachate.

We can then model the body burden of the consumed material and assess the overall risk posed by the item.

Cheers!

Heating up food in a lead-containing dish can speed up the lead-leaching process.
This means to me that an oven or a microwave causes leaching. I didn't say that only a microwave causes this to happen.

A person would not know whether an item is safe or not, not unless we took it to your lab. Better safe than sorry. I gave a long list of what dishes are safe to use.

Lead once entering the body will not be absorbed entirely by our bodies as it is not a trace mineral necessary for body function. That said, there is a portion of lead that will not be excreted and settles in different organs of he body. These deposits, with proper diet, will eventually chelate and leave the body without doing any damage. The problems arise from bad diet (low sulfur intake) but the major problem arises when lead breaks the blood/brain barrier and enters the brain. Many researchers agree that metals that have the ability to cross the blood/brain barrier are the cause of diseases such as autism, Parkinson's, Alzheimer's, ADD and many nervous system functions. This occurs usually with acute exposure; factory/ industrial environments, ongoing environmental exposures like eating fish subject to pesticide runoff.

People are born with varying abilities to absorb and/or excrete different minerals. Some are necessary and some aren't. A great example is a person with so called "Wilson's disease" (lacking the ability to excrete excess copper). These people usually have childhood allergies and asthma, are creative and sensitive. High copper people will always have low Molybdenum levels and with low Molybdenum levels their bodies lack the ability to bind out or chelate metals such as lead and mercury. Thus if Copper is high in the body there is a much greater chance for that person to have high metals counts in the brain. This chain reaction has caused many people that should have been treated for high copper to be diagnosed with anything from mild depression to "incurable" insanity.



Bottom line.............. some get sick and some don't.

dennis, that was a very good post. Thanks for the information. It also made me think of all of those plumbers out there that work with copper daily.
