About the book
Lead is one of the elements that play crucial roles in people’s living. Firstly, its characteristic properties make it a unique metal to be used for specific purposes, especially in batteries, paints, and toys. However, the metal can cause toxicity to human metabolisms including kidneys, blood pressure and central nervous systems. Lead pollutions can be derived from fuel burning, smelting, mining, industry and incinerators. The metal can be contaminated in soil, food, water, dust and air, which makes its analysis necessary. There are a large number of techniques and methods to be selected as convenient with different advantages and disadvantages and they are continuously developed to provide better and better results, especially with the use of nanomaterials. These include UV-Vis spectroscopy, AAS, ICP and electrochemistry. In particular, electrochemistry is prominent for use in onsite simultaneous environmental analysis whereas AAS and ICP need sample preparations before the determination. For geological purposes, isotopic fingerprinting can be very informative to trace the source of pollution. As far as lead is there in this whole wide world, its chemistry is needed to be well developed and understood so that children in the future world can be protected from its impact and they can have the right ways to benefit more from the metal.
