Heavy Metal Test - Lead(Pb)

Home heavy metal test for Lead

Comparisons with bone analysis of very old skeletons have shown that the lead levels in our bodies today are 500 - 1,000 times higher. The total lead content in our body today is estimated at 125-200 mg. Daily intake has been estimated at 1-2 mg with very narrow limits although forunately, most people's exposure is around 300-400 mcg. daily

Lead is a neurotoxin and commonly generates abnormal brain and nerve function. It passes into the brain and can also contaminate the in-utero fetus and breast milk. Most lead, though, is stored in the bones. With lead intoxication, "lead lines" are visible in the bones on X-rays. Some of the lead is also stored in the liver and soft tissues. Infants have very little lead, but our body concentrations usually increase with age.

Lead is not very well absorbed, usually less than 5 percent, though children absorbs it at a higher rate. Many minerals, such as calcium and iron, interfere with further lead absorption. When lead gets into the blood, it does not stay long. Either it gets into the bones and other tissues or eliminated. Most of the lead taken in through food are excreted. Lead which is absorbed or inhaled will usually be cleared by the kidneys and/or perspiration.

A high level of of lead in the urine suggests increased levels in the body, especially in the bones. Since lead interferes with many red blood cell enzymes such as delta-aminolevulinic acid dehydratase, an increase in delta-aminolevulinic acid in the urine, as well as zinc protoporphyrin and erythrocyte protoporphyrin, indicates problems of lead toxicity.
