Seminole Group - Lead

Lead is used vastly in the construction and building industry

Lead is considered to be one of the heavy metals, yet it is a soft, malleable, poor metal that has a bluish tint when freshly cut. In the presence of air lead tarnishes to a dull gray and when melted the liquid is shiny, silver- chrome.

Lead has the highest atomic number of all the stable elements. It is a true metal that is highly resistant to corrosion, and because of this property it is used to contain corrosive liquids. It is also extensively used in building construction.

Lead is a neurotoxin that accumulates in soft tissue and acts specifically on nerve cells; it is poisonous to living organisms.
