We have discussed the harmful effects of lead at length now. But why was lead widely used despite its hazardous impact? Undoubtedly, it was because lead was a useful metal. Let us now look at some of the usages of lead.
In the olden days, lead was used as a building material. It was used as a pigment for glazing ceramics. Water pipes were coated with lead. Today, the most prominent use of lead is to build lead-acid storage batteries. The electrical systems of vehicles, ships, and aircraft depend on such batteries for startup, and in some cases, batteries provide the actual motive power.
Have you heard of sound-proof rooms? Lead is used for soundproofing office buildings, schools, and hotels. It is widely used in hospitals for protection against X-ray and gamma radiation. Lead is also employed as a shield against harmful nuclear radiation.
