Abstract
Background: Speciation analysis is defined as the identification and/or measurement of the quantities of one or more individual chemical species in a sample. The knowledge of elemental species provides more complete information about mobility, bioavailability and the impact of elements on ecological systems or biological organisms. It is no longer sufficient to quantitate the total elemental content of samples to define toxicity or essentiality. Thus speciation analysis is of vital importance and generally offers a better understanding of a specific element.
Discussion: Thorough speciation scheme consisting of sampling, sample preparation, species analysis and evaluation was described. Special emphasis is placed on recent speciation analysis approaches, including both direct and coupling methods. An updated summary of advantages and limitations of the various methods as well as an illustrative comparison is presented. Certain elements and species of interest are briefly mentioned and practical examples of speciation applications in tobacco and other important economic crops are also discussed.
Aim/Conclusion: This review aims to offer comprehensive knowledge about elemental speciation and provide readers with valuable information. Many strategies have been developed for the determination of multiple elemental species in tobacco and other important economic crops. Nevertheless, it is an eternal pursuit to establish speciation methods which can balance accuracy, agility as well as universality.
Keywords: Chemical species, speciation analysis, direct methods, coupling methods, tobacco, heavy metal.
