  • Lead – Its Effects on Environment and Health - Environmental Impact of Alkyl Lead(IV) Derivatives: Perspective after Their Phase-out.
    Metal ions in life sciences, 2017
    Co-Authors: Montserrat Filella, Josep Bonet
    Abstract:

    The use of alkyl lead derivatives as Antiknock Agents in gasoline can be considered as one of the main pollution disasters of the 20th century because of both the global character of the pollution emitted and the seriousness of the impact on human health. Alkyl lead derivatives in themselves cannot be considered to be persistent pollutants because they readily degrade either before being released from the tailpipes or soon afterwards in the atmosphere. However, the inorganic lead they produced has been deposited in soils all over the planet, largely, but not exclusively in urban areas and along motorways, since the direct emission of lead into the atmosphere favored its dispersal over great distances: The signal of the massive use of alkyl lead derivatives has been found all over the world, including in remote sites such as polar areas. The short residence time of lead in the atmosphere implies that this compartment is highly responsive to changes in emissions. This was demonstrated when leaded gasoline was phased-out and is in striking contrast to the very long permanence of inorganic lead in soils, where resuspension is a permanent source of toxic lead.

  • Chapter 12 – Silicon, Germanium, Tin, and Lead
    Descriptive Inorganic Chemistry, 2016
    Co-Authors: James E. House
    Abstract:

    Because it is sometimes found uncombined, lead has been known since antiquity. Tin is easily reduced from SnO2 and it too has been known for centuries, and when alloyed with copper the alloy bronze is produced. Although discovered much later, Mendeleev predicted the existence of an element having the properties of germanium. Alloys of tin and lead are useful in applications such as solder. Silicon and germanium are used in the electronics industry. Silicates are among the most common rocks and minerals, and, as a result of the many ways in which SiO4 tetrahedral can be arranged, numerous structures are known. All of the elements form organometallic compounds. Although alkyl lead compounds were used as Antiknock Agents in fuels for many years, the silicon compounds, especially the silicones, are now much more important.
