Lead was used a lot until the discovery of lead poisoning. It is known and used for its high density and its ability against corrosion. Many products that use to use lead no longer do. People do not want lead to leak out into the environment. Examples of these include ammunition, sheet lead used in building construction, water and sewer pipes, ball bearings, and gasoline. Manufacturers are finding safer elements to use in the place of lead. Lead can be used for its metal form and its chemical compounds.
Some lead uses are:
- lead acid battery (car battery)
- colouring for ceramic glazes
- used in polyvinyl chloride (coats for electrical cords)
- projectiles for firearms
- fishing sinkers
- sheet lead for sound proof rooms
- shielding from radiation
- molten lead used for cooling
- roofing material, gutters and gutter joints, and on roof parapets
- some statues and sculptures
- to balance the wheel of a car
- solder
- ballast in boats
