What is the most toxic metal?
Mercury is considered the most toxic heavy metal in the environment.
Mercury poisoning is referred to as acrodynia or pink disease..
What happens if you eat antimony?
Studies in workers, who are typically exposed to higher levels of antimony, show that breathing antimony dust can cause heart and lung problems, stomach pain, diarrhea, vomiting, and stomach ulcers. Swallowing large doses of antimony can cause vomiting in people.
Is antimony a heavy metal?
Other examples include manganese, chromium, cobalt, nickel, copper, zinc, silver, antimony and thallium. Heavy metals are found naturally in the earth. … Some elements otherwise regarded as toxic heavy metals are essential, in small quantities, for human health.

Where is Antimony most commonly found?
Antimony is sometimes found in pure form. It is also obtained from the mineral stibnite (antimony sulfide) and commonly is a by-product of lead-zinc-silver mining. Other antimony-bearing minerals include sibiconite, tetrahedrite and ullmannite. It is mined in China, Bolivia, South Africa and Mexico.
Is antimony a metal or nonmetal?
Antimony. Antimony is a semimetallic chemical element which can exist in two forms: the metallic form is bright, silvery, hard and brittle; the non metallic form is a grey powder. Antimony is a poor conductor of heat and electricity, it is stable in dry air and is not attacked by dilute acids or alkalis.
Is Copper toxic to humans?
Copper is essential for good health. However, exposure to higher doses can be harmful. Long-term exposure to copper dust can irritate your nose, mouth, and eyes, and cause headaches, dizziness, nausea, and diarrhea. … Intentionally high intakes of copper can cause liver and kidney damage and even death.
Which is the heaviest metal?
OsmiumOsmium 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.
How much antimony is lethal?
The lethal oral dose of metallic antimony in rats is 100 mg/kg of body weight; the trivalent and pentavalent oxides are less toxic, with LD50 in rats ranging from 3200–4000 mg/kg of body weight. The recommended workplace limit (ACGIH TLV-TWA) for antimony is 0.5 mg/m3 as an 8-hour time-weighted average.
What is antimony used in?
A lead-antimony alloy is used in batteries. Other uses of antimony alloys include type metal (in printing presses), bullets and cable sheathing. Antimony compounds are used to make flame-retardant materials, paints, enamels, glass and pottery. Antimony and many of its compounds are toxic.
Is antimony shiny or dull?
Four allotropes of antimony are known: a stable metallic form and three metastable forms (explosive, black and yellow). Elemental antimony is a brittle, silver-white shiny metalloid.
Why is Tungsten W?
Tungsten comes from a Swedish term, tung sten, that means “heavy stone.” Tungsten’s chemical symbol is a W, which may seem weird since there isn’t a W in the word. The W actually comes from the element’s other name, wolfram. The name wolfram comes from the mineral the element was discovered in, wolframite.
How does antimony affect the body?
Antimony in the air can cause lung effects in workers and laboratory animals. Antimony can also cause heart problems. It can damage the heart muscle and cause changes in electrocardiogram (EKG) readings. High levels of antimony in drinking water can cause vomiting and abdominal pain.
Is antimony used in medicine?
Today, neither metallic antimony nor its compounds have a medical use, although up to the 1970s, antimony compounds were used to treat parasitic infections like schistosomiasis. These preparations did kill the parasites, but sometimes they also dispatched the patient.
Is antimony a lead?
The most common and important metal alloyed with lead is antimony. Antimonial lead alloys usually contain from 1 to 6 percent antimony, but they may contain as much as 25 percent. Other components usually include tin, iron, copper, zinc, silver, arsenic, or traces…
