Overview:
It is well known that the distribution, mobility, toxicity and biological bioavailability of chemical elements depends not on their concentration but, critically, on the specific chemical form. Elemental speciation measurements and identification has now entered reliable and validated methods to understand, monitor and control the impact of trace elements for improved industrial applications, better overall environmental management. This symposium displaying hyphenated techniques based on plasma spectrometry and mass detection will expose the audience to unifying concepts and critical issues in the understanding of the chemical behavior of elements and elemental species in these different domains of everyday life. It will showcase real world applications in which elemental speciation measurement and research is being utilized on a reliable and routine basis to address current major environmental and biological concerns and the influence of metal speciation on risk assessment and risk management.
