Galena, a lead sulfide (PbS), is heavy, brittle, and breaks into cubes. Sphalerite is a zinc sulfide (ZnS) mineral that is brownish, yellowish, or black. It ordinarily occurs with galena and is a major ore of zinc. The iron sulfide pyrite (FeS), which is also called fool’s gold, is common in nearly all types of rocks.

Lead is widely distributed all over the world, and has been known since ancient times. Elemental lead is rarely found in nature. Lead is present in ores such as galena (cubic lead sulfide, PbS), anglesite (rhombic lead sulfate, PbSO 4), cerussite (rhombic lead carbonate, PbCO 3), minim (a form of lead oxide with formula Pb 3 O 4), and other ...

The Centers for Disease Control and Prevention also issued guidelines about ingesting certain folk medicines which contain a high level of lead and may expose people to lead or lead compounds. For example Daw Tway is a digestive aid used in Thailand and Myanmar (Burma). Analysis of Daw Tway samples showed as much as 970 parts per million (ppm ...
