Heavy Metal Toxicity Heavy metal accumulation in the system can have a profound effect on the proper functioning of various organs. Problems ranging from poor circulation to liver toxicity to neurological disorders can arise when certain metals are present at elevated levels within the body. It is therefore important to know which of these metals are the most detrimental to health and how we can prevent exposure to them as well as how we can remove these from the body (chelation). Lead (Pb) is perhaps the most common heavy metal people are exposed to everyday from such sources as exhaust fumes, paint, plastics and lead water pipes. e average person absorbs approximately 10-20 mg of Pb through digestion, the respiratory system and the skin. While 75% of that amount is excreted normally, the remaining 25% is deposited in the blood, tissues and bone. Even low levels of Pb in the bloodstream affect the body's ability to utilize calcium, magnesium, zinc, and other minerals. Lead levels greater than 100 mg/dL will result in various brain disorders, coma, and severe cramping. Lead can also cause anemia, which can be mistaken for iron deficiency anemia. is is because lead can inhibit the incorporation of iron into protoporphyrin, restricting the production of hemoglobin, leading to an accumulation of iron in the red blood cells. is can be recognized under the microscope as bluish intra-cellular deposits. Other signs of lead poisoning include the presence of lead sediments lining the gums and teeth and the inability to use forearm and leg muscles which leads to a wrist or foot drop. Keeping in mind that the effects of lead on the body are very damaging, special care should be taken when watching for potential dangers in the home. Lead water pipes can leave debris in our water, which would be hazardous considering that if each deciliter of blood contains any more than 60 mg lead, permanent brain damage, especially to infants and young children, can occur. In pregnant women, this risk is especially dangerous as it could affect the development of the child's central nervous system. Mercury (Hg), another toxic element, can cause hyperactivity, mental and emotional changes, neuromuscular disorders and loss of appetite, among other symptoms. A high level of Hg is a risk factor in myocardial infarction and cardiovascular disease. Large amounts can also lead to severe kidney damage and digestive tract damage. Very low levels of mercury have been found to suppress biologically imperative selenium activity. Amalgam (tooth filling), seafood, water supply, hemorrhoid medications and skin lightening agents are sources of mercury. Cadmium (Cd) is another harmful metal that can be found in so drinks, hair dyes, batteries and cigarette smoke, among other sources. It is also found naturally in the earth, so we oen unknowingly consume it through agricultural products, especially in potatoes and in wheat. Cadmium enters the system in its metal/salt form. Once it enters the bloodstream, the portion stored in the kidneys and liver is excreted out while the rest is accumulated in the brain, muscles, bones, pancreas and spleen. Problems that result from cadmium toxicity include renal dysfunction, chronic fatigue system, high blood pressure, hair loss and impotence. Aluminum (Al) is oen neglected because the human body responds very slowly to it. Nevertheless, medical research has shown that an excessive amount of aluminum in the body can cause progressive dementia, bone disease and anemia. Because aluminum is the most common metallic element on earth, everyone is exposed to low levels of it. Sources include cooking utensils, aluminum cans, antacids, and antiperspirants. Awareness of the dangers of heavy metal toxicity is just the first step. Having yourself checked for heavy metals is even more important. Conventionally, a blood, urine or hair analysis will determine heavy metal toxicity. An easier and quicker way is to look for physical sign indicating heavy metal toxicity: black or dark-colored nails; blue or black protruding veins under the tongue; blue or dark-colored gums; or a metallic taste in the mouth. Dr. Chi's Method of Fingernail and Tongue Analysis provides more details and examples diagnosing heavy metal toxicity and other conditions using the tongue, nails and other physical signs. If you possess any of these indicators and have been or are exposed to heavy metals, you may have metal accumulation in your system. Once metal poisoning is ascertained, it usually takes three to six months to completely remove the heavy metals from the system since they deposit in bones, fat and tissues.
