Where is lead found naturally?
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..
What are the main sources of lead?

Where is lead poisoning most common?
Lead-based paint and lead-contaminated dust in older buildings are the most common sources of lead poisoning in children. Other sources include contaminated air, water and soil. Adults who work with batteries, do home renovations or work in auto repair shops also might be exposed to lead.
What will dissolve lead?
Lead metal resists sulfuric and phosphoric acid but not hydrochloric or nitric acid; the outcome depends on insolubility and subsequent passivation of the product salt. Organic acids, such as acetic acid, dissolve lead in the presence of oxygen. Concentrated alkalis will dissolve lead and form plumbites.
What is lead used for now?
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 safe to touch?
Some studies have found lead can be absorbed through skin. If you handle lead and then touch your eyes, nose, or mouth, you could be exposed. Lead dust can also get on your clothes and your hair. If this happens, it’s possible that you may track home some of the lead dust, which may also expose your family.
Where does the lead come from?
Lead is a toxic heavy metal found in mineral deposits in the earth’s crust. It does not usually occur naturally in drinking water, but can be present from the use of lead-based solder or lead pipes, or from a contaminated water source.
Is lead natural or manmade?
Lead is a naturally occurring bluish-gray metal found in small amounts in the earth’s crust. Lead can be found in all parts of our environment. Much of it comes from human activities including burning fossil fuels, mining, and manufacturing. Lead has many different uses.
What is the most likely source of lead?
Lead-based paint and lead contaminated dust are the most common sources of lead exposure for children. Lead was used in common house paint until 1978 when the Consumer Product Safety Commission (CPSC) restricted its use in household paint. Many buildings built before 1978 have lead-based paint inside and outside.
Does lead ever leave the body?
Your body does not change lead into any other form. Once it is taken in and distributed to your organs, the lead that is not stored in your bones leaves your body in your urine or your feces.
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. Chelation, though, is not without its risks.
