Typical mean Pb concentration for surface soils worldwide averages 32 mg kg 1 and ranges from 10 to 67 mg kg 1 . It is a naturally occurring, bluish-gray metal usually found as a mineral combined with other elements, such as sulphur (i.e., PbS, PbSO 4), or oxygen (PbCO 3), and ranges from 10 to 30 mg kg 1 in the earths crust . Metals are typically ductile (can be drawn into wires) and malleable (they can be hammered into thin sheets). Carbon may make up only 0.2% of the earths crust, but it certainly deserves a whole branch of chemistry all to itself.

Aluminium Typical mean Pb concentration for surface soils worldwide averages 32 mg kg 1 and ranges from 10 to 67 mg kg 1 . A large Organic complexes of aluminium may be easily absorbed and interfere with metabolism in mammals and birds, even though this rarely happens in practice. A solar cell, or photovoltaic cell, is an electronic device that converts the energy of light directly into electricity by the photovoltaic effect, which is a physical and chemical phenomenon. A metal (from Greek mtallon, "mine, quarry, metal") is a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. Some metals like gold, silver, platinum etc are found in the free state in the earths crust because they are least reactive. It is this ability to form bonds to itself that leads to the variety of organic structures that exist, and indeed to the possibility of life existing at all. Sulfur is abundant and occurs throughout the Universe, but it is rarely found in a pure, uncombined form at Earth's surface.
