Lead pollution can coat the surface of a leaf and reduce the amount of light reaching it. This results in stunting the growth or killing the plants by reducing the rate of photosynthesis.


Lead’s chemical symbol is Pb. Which comes from its Latin name, plumbum.

Tiny splinters, called whiskers, in electronic devices have caused damages of over $10 billion. Small quantities of lead added to the tin in devices significantly reduce the formation of whiskers.The tin whiskers have produced many of NASA's failures.So, without lead the world would experience more technical failures.

Lead metal reacts vigorously with fluorine and chlorine

Lead has been around for thousands of years. It is impossible to say when and who first discovered the element.

Today, Lead is used in bullets, batteries, the ballast keel of sailboats and scuba diving weight belts

Lead is an Anglo-Saxon word for the metal that was used since ancient times.

more than 60% of buildings constructed before 1978, and almost 90% of buildings constructed before 1940, contain lead.

Lead Poisoning Lead poisoning is caused by a build up of lead or even a small amount of lead in the body. At very high levels, it can be fatal. You can ingest lead or you can breath in dust that contains it. Children under 6 are at a higher risk.
