Metal Toxicity Presentation


Metal Toxicity: Sources, Symptoms, Testing and Treatment


The air we breathe can contain many toxic metals due to coal combustion, tire wear, and other sources.  Cigarette smoking and second hand smoke can cause inhalation of cadmium, antimony, barium, thallium, and others.  Even if one discontinues cigarette smoking after 15 years, elevated cadmium levels can persist due to its long half-life.  Drinking water can contain toxic metals such as arsenic and bottled water has been found to have antimony.  Mining can also release toxic metals into the air and the water table.  Food and dental amalgams can contain mercury.  Fillers in medications and supplements, as well as antacids and cosmetics can contain bismuth.  Aluminum can be absorbed from anti-perspirants.

Toxic metals can cause decreased mentation, memory loss, joint pain, cardiovascular disease, cancer, and many other problems.  Of particular concern is cadmium from cigarettes which can cause both cardiovascular disease and cancer.
