Lead’s high density makes it useful as a shield against X-ray and gamma-ray radiation and is used in X-ray machines and nuclear reactors. Lead is also used as a covering on some wires and cables to protect them from corrosion, as a material to absorb vibrations and sounds and in the manufacture of ammunition.
Why is lead useful?
Lead is still widely used for car batteries, pigments, ammunition, cable sheathing, weights for lifting, weight belts for diving, lead crystal glass, radiation protection and in some solders. It is often used to store corrosive liquids.
Is lead essential to life?
There is no safe level of lead
Though lead is found frequently in our environment, it has no known purpose in our bodies. When lead gets inside the body, the body confuses it with calcium and other essential nutrients. This confusion can cause permanent damage to the health of both children and adults.
Where is lead useful?
Lead and lead compounds have been used in a wide variety of products found in and around our homes, including paint, ceramics, pipes and plumbing materials, solders, gasoline, batteries, ammunition and cosmetics.
What are 3 interesting facts about lead?
Interesting Lead Element Facts
- Lead has atomic number 82, which means each lead atom has 82 protons.
- Lead is a considered a basic metal or post-transition metal.
- Lead is one of the metals that was known to ancient man.
- Over half the lead produced today is used in lead-acid car batteries.
- Lead is highly toxic.
What was lead used for in ancient times?
Lead was one of the earliest metals discovered by the human race and was in use by 3000 B.C. The ancient Romans used lead for making water pipes and lining baths, and the plumber who joins and mends pipes takes his name from the Latin word plumbum, meaning lead.
Why does lead make us sick?
Lead exposure can have serious consequences for the health of children. At high levels of exposure lead attacks the brain and central nervous system, causing coma, convulsions and even death. Children who survive severe lead poisoning may be left with intellectual disability and behavioural disorders.
How does lead impact society?
The lead in fuels contribute to air pollution, especially in urban areas. Soils near highways, freeways, and smelting facilities have higher levels of lead than soils in other areas because of their exposure to lead dust, which accumulates over time.
How does lead enter our body?
Lead enters the body primarily through inhalation and ingestion of lead containing dust. Once in the body, lead travels in the blood to soft tissues such as the liver, kidneys, lungs, brain, spleen, muscles, and heart.
How does lead affect the ecosystem?
Other sources of lead to ecosystems include direct discharge of waste streams to water bodies and mining. Elevated lead in the environment can result in decreased growth and reproduction in plants and animals, and neurological effects in vertebrates.
What industries use lead?
Lead is widely used in batteries, cable sheaths, machinery manufacturing, shipbuilding, light industry, lead oxide, radiation protection and other industries.
Why is lead more common than gold?
So to narrow down and answer your question: Lead (Pb) tends to be more abundant than Gold (Au) because it has an even number of protons in its nucleus (82 versus 79) and its inner electron shells are filled (Basic Metal versus Transition Metal).
What things are made of lead?

What are 5 physical properties of lead?
Its properties include a low melting point; ease of casting; high density; low strength; ease of fabrication; acid resistance; electrochemical reaction with sulfuric acid; chemical stability in air, water, and soils; and the ability to attenuate sound waves, atomic radiation, and mechanical vibration (11).
Is lead still used?
The largest use for lead is in storage batteries in cars and other vehicles. Lead compounds are used as a pigment in paints, dyes, and ceramic glazes, and in caulk. Lead paint was banned for consumer use in 1978 in the U.S.; however, it is still used in industrial paints such as those used on cars, bridges, and ships.
Why did Romans use lead?
The Romans used lead in their plumbing and piping, as it was malleable and easy to beat into thin sheets. In fact, the word plumbing actually comes from the Latin plumbum, meaning lead. Pots and cooking utensils were often lined with lead to prevent copper’s bitter taste from spoiling the food.

In medieval times, lead was used for ammunition, roofing, coffins, cisterns, tanks, and gut- ters, and for statues, ornaments, coins, medallions and paints.
What happens if you eat lead?
The greatest risk is to brain development, where irreversible damage can occur. Higher levels can damage the kidneys and nervous system in both children and adults. Very high lead levels may cause seizures, unconsciousness and death.
Can your body get rid of lead?
The damage lead causes cannot be reversed, but there are medical treatments to reduce the amount of lead in the body. The most common is a process called chelation – a patient ingests a chemical that binds to lead, allowing it to be excreted from the body.
Why is lead poisoning prevention taken seriously?
Exposure to lead can seriously harm a child’s health, including damage to the brain and nervous system, slowed growth and development, learning and behavior problems, and hearing and speech problems.
