Uranium and Plant Metabolism

Measurement and Application


Über dieses Buch

This book explores the uranium uptake by plants and its impact on plant physiology and biochemistry. In the first part of this work, the author summarizes the chemistry of uranium, its use and its environmental distribution. Then, particular attention is given to the methods for uranium detection, and to the plant biochemical reactions that influence the uranium uptake. Readers will also discover several strategies adopted by cells to immobilize and handle uranium.


1. Introduction
Elements with atomic numbers >89 are named actinides or, in the case of atomic numbers >103, transactinides. All isotopes of these elements are unstable due to radioactive decay. However, some isotopes of these elements have long radioactive lifetimes. Therefore, these isotopes can play an important role for living species. These heavy elements are non-essential and they are among hazardous elements due to their radioactive decay. In addition, also the chemical speciation influences the toxicity.

2. Modern Methods of Uranium Detection
Uranium may be detected by various methods. Some of these methods show very low detection limits. Of higher interest are methods which allow the determination of the speciation under environmental concentrations and conditions. Some of often used methods in uranium chemistry are summarized.
Gerhard Geipel
3. Chemistry of Uranium
The chemistry of uranium will be described as short overview. The main oxidation states and the preferred detection methods for uranium species are described. In case of uranium(VI) the luminescence emission properties as known up to now are compilated.
Gerhard Geipel
4. Uranium and Relevant Bioligands
Some known uranium complexes, relevant to biologic systems were summarized.

5. Uranium Uptake, Storage and Metabolism by Plants
The influence of the binding form as well as its redox properties are in the focus for the uptake of this element by living organism. In the literature many references can be found, dealing only with transfer factors for the uptake. However, many biochemical reactions influence this uptake and as this element non-essential for life, several strategies for the further handling by the cell are possible and will be discussed.
Gerhard Geipel
6. Outlook
The outlook will give the reader an idea in which field future studies will deal with. However, also other directions may be possible. The most important resume is, that in future only multi-analytical approaches will guide to new and evident knowledge.
