WORKING GROUP ON SPECIATION
Number: 523/10/95
Title: Determination of Selenium Species in Environmental Samples
Coordinator(s): C.
Camara
Completion Date: 1999 - project abandoned
Objective:
The aim is to review critically methods for the analysis
of selenium species in environmental samples (as opposed to biological
samples), to offer guidance on method in use, and to briefly indicate
future developments. Selenium is one of the most important elements
in terms of human, animal and plant nutrition, showing toxicity as well
as being a modifier of geochemical cycling of trace elements. There
is a growing demand for selenium speciation in the environment as the
functions and the dynamics of selenium are to be understood on the basis
of its chemical species. A critical review of analytical methods of
selenium in the environment, and a guidance on the method use will be
given in the project. The project is important for world chemists not
only because of its scientific significance but also of its wide application
in different fields. Although other international bodies and scientific
bodies have shown their interest in this type of project, IUPAC is the
most appropriate unit to do because of its capacity in science and good
coverage of chemists of high quality and of geological distribution.
Progress:
New draft received, but needs considerable editing. It is not certain
that present co-ordinator is willing to make modifications. Contact
will be sought. If neccessary, J. Edmonds and R. Lobinski will join
team and ensure that paper is ready at next GA meeting (Berlin).
Most of the contents will be merged into another project on selenium
523/6/91, that will be submitted
during '99. In consequence, this project is considered abandoned.
