Most industrial exposure is from breathing inorganic lead dust and fumes. Eating, drinking and smoking on the work site or carelessly handling contaminated objects can result in unintentional exposure to lead. Once it enters the body, lead is stored in three places: the blood, body organs and bones.
It is bluish-white, very dense, and has a low melting point. Lead is found in veins and masses in limestone and dolomite. It is also found with deposits of other metals, such as zinc, silver, copper, and gold. Lead is essentially a co-product of zinc mining or a byproduct of copper and/or gold and silver mining. Complex ores are also the source of byproduct metals such as bismuth, antimony, silver, copper, and gold. The most common lead-ore mineral is galena, or lead sulfide (PbS). Another ore mineral in which lead is found combined with sulfur is anglesite or lead sulfate (PbSO 4).
