Global warming has worsened the water resource crisis in many arid zones worldwide, from Africa to Asia, affecting millions of people and putting them at risk of hunger. Effective management of arid zone resources, including understanding the risks of toxic trace and heavy elements to humans, coupled with the need to produce more food to feed the world s growing population, has thus become increasingly important. This very timely book, the only one of its kind on the market, fills the gap of our knowledge of trace elements in these regions.

Topics include:

- content and distribution
- solution chemistry
- solid-phase chemistry
- selective sequential dissolution techniques
- transfer fluxes
- bioavailability
- pollution and remediation

In order to illustrate the themes, a comprehensive and focused case study is presented, and the book closes with the global perspectives on anthropogenic interferences in the natural trace elements distribution.
