What Is Lead?

Lead is a heavy metal that is found in mineral deposits in the earth’s crust. It is malleable, a poor conductor of electricity and resistant to corrosion. It may be used in its pure elemental form or combined chemically with other elements to form lead compounds.

Where Is It Used?

Inorganic lead compounds are used in pigments, paints, glasses, plastics and rubber compounds. It can be in materials such as paints, coatings, mortar, concrete, solder, batteries, ammunition, sheet metal and in devices to shield X-rays. It must be noted that all the paints for indoor use are lead-free now in Canada.

Why Is Lead a Concern?

When lead is inhaled or ingested, it enters the bloodstream and travels to our liver, kidneys, lungs, brain, spleen, muscles and heart. It’s stored in the body for a long period. Exposure to even a small amount of lead can build up over time and causes health problems. Small amounts of lead are very harmful to infants, children and pregnant women.

A low exposure can harm the intellectual development, behavior, size and hearing of infants and children. During pregnancy, lead can cross the placenta and affect the health, growth and development of the unborn child.
