What are heavy metals used for?

Heavy metals are relatively scarce in the Earth’s crust but are present in many aspects of modern life. They are used in, for example, golf clubs, cars, antiseptics, self-cleaning ovens, plastics, solar panels, mobile phones, and particle accelerators.

Why are heavy metals called heavy?

“Heavy metals” are natural elements characterized by their rather high atomic mass and their high density. Although typically occurring in rather low concentration, they can be found all through the crust of our planet.

How many heavy metals are there?

There are 35 metals that are of concern for us because of residential or occupational exposure, out of which 23 are heavy metals: antimony, arsenic, bismuth, cadmium, cerium, chromium, cobalt, copper, gallium, gold, iron, lead, manganese, mercury, nickel, platinum, silver, tellurium, thallium, tin, uranium, vanadium.

Which is the heaviest metal?

Osmium is one of the heaviest materials on earth, weighing twice as much as lead per teaspoon. Osmium is a chemical element in the platinum group metals; it’s often used as alloys in electrical contacts and fountain pen nibs.

What are the symptoms of heavy metals in the body?


  • Abdominal pain, nausea, vomiting, and diarrhea (the hallmark symptoms with most cases of acute metal ingestion)
  • Dehydration.
  • Heart abnormalities such as cardiomyopathy or abnormal heart beat (dysrhythmia)
  • Nervous system symptoms (e.g. numbness, tingling of hands and feet, and weakness)

How long do heavy metals stay in the body?

According to various studies that heavy metal chelation using cilantro and chlorella can naturally remove an average of 87% of lead, 91% of mercury, and 74% of aluminum from the body within 45 days.

What are the signs of heavy metal poisoning?

What qualifies as a heavy metal?

The term heavy metal refers to any metallic chemical element that has a relatively high density and is toxic or poisonous at low concentrations. Examples of heavy metals include mercury (Hg), cadmium (Cd), arsenic (As), chromium (Cr), thallium (Tl), and lead (Pb).

How long do heavy metals stay in your body?

What is the most densest thing on earth?

element osmium
At the modest temperatures and pressures of Earth’s surface, the densest known material is the metallic element osmium, which packs 22 grams into 1 cubic centimetre, or more than 100 grams into a teaspoonful. Even osmium is full of fluff, however, in the form of electron clouds that separate the dense atomic nuclei.

How do you get rid of heavy metal poisoning?

The main treatment of heavy metal poisoning is termination of exposure to the metal. Treatment also consists of the use of various chelating agents that cause the toxic (poison) element to bind with the drug and be excreted in the urine.
