Area of Science:

  • Analytical Chemistry
  • Environmental Science

Background:

  • Element speciation, the study of distinct forms of an element, is vital for understanding its behavior and impact.
  • Accurate speciation is essential in various fields, including environmental monitoring and toxicology.
  • Traditional analytical methods often fail to preserve or accurately identify different element species.

Purpose of the Study:

  • To define element speciation and elucidate the necessity for species-specific analysis.
  • To identify and discuss challenges encountered during sampling, sample preparation, storage, and separation techniques.
  • To explore the advantages of specific separation and detection methods, particularly inductively coupled plasma-mass spectrometry (ICP-MS), in element speciation.

Main Methods:

  • Review of current literature on element speciation challenges and advancements.
