heavy metal poisoning poisoning with any of the heavy metals, particularly antimony, arsenic, cadmium, lead, mercury, thallium, or zinc.
noble metal a metal that is highly resistant to oxidation and corrosion.

heav·y met·al

a metal with a high specific gravity, typically larger than 5, for example, Fe, Co, Cu, Mn, Mo, Zn, V.
Toxicology A metal that is 5 times heavier than water and often toxic, a feature linked to the heavy metal’s tight cationic binding to circulating proteins
Examples Antimony, arsenic, bismuth, cadmium, copper, lead, mercury; cells respond to heavy metals by upregulating transcription of various genes—e.g., the eukaryotic heat shock system, metallothioneins, prokaryotic mercury resistance gene and iron uptake systems
Management EDTA chelation
Vox populi Metal A style of energetic, loud rock music

Patient discussion about heavy metal

Q. I was told that platinum is used in fragrances for the fullness of the spray. Please tell me more! Three years ago I was diagnosed with off the lab chart levels of platinum in my body. I have no hobby or avenue for exposure other than my work. I have sold fragrances for over ten years. Even the Regional EPA Air Quality person doesnt know where I am getting this. I was told by a health director who made some calls. He told me that platinum is used in fragrances for the "fullness of the spray". Would you please tell me more about this? Thank you!

A. Thank you Joseph83! What list of materials shall I look at? I know that the FDA doesn't regulate these products; also, I wonder if there is a masking name for platinum. I have so much of this in me, it just has to come from somewhere! I'm amazed that the EPA SUPPOSEDLY doesn't know where its coming from either.
