About Lead

Lead is one of the oldest known chemical elements known and used since the times of the Roman Empire. It is a not shiny, quite soft and toxic heavy metal which can be easily worked. The name for it is derived from the Latin word meaning metal. Lead has no importance for biological life but it can be found in living organisms in micro amounts. If the amounts are larger, lead can be toxic and carcinogenic. Lead is extracted from a few natural sources, and it can be successfully recycled from its secondary sources. Lead forms a large number of chemical compounds which have applications in a variety of industries, including battery production, producing some equipment for sports, printing presses, glass, ammunition, pigments, pesticides, and so on.
