In short, gold is both a mineral and a metal, making it a dynamic precious metal with a wide array of applications.

Yes. Minerals have to occur naturally, be crystalline, be solid, and have a specific chemical composition. Any metal that you could find in a rock while walking around is a mineral. A lot of minerals include metals in their chemical formula and some minerals are pure metals, such as gold, silver, and copper.

Minerals are made of chemicals – either a single chemical element or a combination of chemical elements. Metal- An alloy of two or more metallic elements. Therefore, Rocks have minerals, which in large concentration are called ores and these are mined for metals!

Lead (element #82, symbol Pb) is a very soft, blue-gray, metallic element. It is primarily produced from the mineral galena. It has been used since antiquity.

Lead comes from a mineral called galena. It is not used in paints any more – titanium is used instead.

Diamond, a mineral composed of pure carbon. It is the hardest naturally occurring substance known; it is also the most popular gemstone.

Lead is a bluish-white lustrous metal. It is very soft, highly malleable, ductile, and a relatively poor conductor of electricity. It is very resistant to corrosion but tarnishes upon exposure to air.

Lead can be found in all parts of our environment – the air, the soil, the water, and even inside our homes. Much of our exposure comes from human activities including the use of fossil fuels including past use of leaded gasoline, some types of industrial facilities and past use of lead-based paint in homes.

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).

As the body naturally gets rid of the lead, the level of lead in the blood falls. Kids with severe cases and extremely high lead levels in their blood will be hospitalized to get a medicine called a chelator.

A simple blood test can detect lead poisoning. A small blood sample is taken from a finger prick or from a vein. Lead levels in the blood are measured in micrograms per deciliter (mcg/dL).

Vitamin C helps the body absorb iron better, but also may help with getting rid of lead. Foods rich in vitamin C include: Citrus fruits, such as oranges and grapefruit….Foods that are a good source of iron include:

1. Lean red meats.
2. Iron-fortified cereals, bread and pasta.
3. Beans and lentils.
4. Cooked spinach and potatoes.

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.
