Where can lead be found in nature?
Lead is found in nature, rarely in pure form but in ores with other metals — the most abundant one in the Earth’s crust being galena (PbS). Natural formation of lead occurs by radioactive decay of uranium and thorium through radon (222Rn).
Why was lead so commonly used?
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.
Can lead be removed from the body?
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.
Is lead toxic to touch?
Children get lead in their bodies by putting the lead-containing objects in their mouths. Touching the lead and then putting their fingers in their mouths may also poison them. Lead is more harmful to children because their brains and nervous systems are still developing.
How common is lead?
Lead poisoning is very common. 1 in 40 children ages 1-5 years old have blood lead levels that are considered unsafe (over 5 µg/dL).
How soft is lead?
Lead is a very soft metal with a Mohs hardness of 1.5; it can be scratched with a fingernail. It is quite malleable and somewhat ductile. … The melting point of lead—at 327.5 °C (621.5 °F)—is very low compared to most metals.
Who first discovered lead?
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.
What is special about lead?
Lead (Pb) is one of the most infamous elements in the periodic table. Though it’s now widely known as the source of lead poisoning, humans have been using the heavy metal for thousands of years. It’s soft, has a relatively low melting point, is easy to shape, and doesn’t corrode much, making it incredibly useful.
What happens if you test positive for lead?
The blood lead test tells you how much lead is in your child’s blood. Lead can harm a child’s growth, behavior, and ability to learn. The lower the test result, the better. Most lead poisoning occurs when children lick, swallow, or breathe in dust from old lead paint.
