The execution of detailed studies on the fate and levels of
hazardous elements in the environment, foodstuffs and in human
beings has become a major task in environmental research and
especially in analytical chemistry. This has led to a demand to
develop new methodology and optimize that already in use.
The book offers the reader a general introduction to the problem
areas that are currently being tackled, followed by chapters on
sampling and sample preservation, strategies and applications of
the archiving of selected representative specimens for long-term
storage in environmental specimen banks. This is supplemented by
the example of wine as a preserved - frequently, already historical
- specimen which clearly reflects technological changes over time.
The following chapters review sample treatment, present an overview
on the most frequently and successfully applied trace analytical
methods for metals and metal compounds, and introduce the
increasingly important methods for identifying and quantifying
metal species in sediments and soils (speciation).
The chapters in the second part of the book provide data on
analytical methods for determining the levels of toxicologically,
ecotoxicologically and ecologically important elements in
environmental and biological materials, including information on
the separation and quantification of chemical and organomatallic
species. The elements treated are aluminium, arsenic, cadmium,
chromium, cobalt, lead, mercury, nickel, selenium and thallium. The
final chapter treats quality assurance and the importance of the
continuous use of appropriate reference materials to avoid
erroneous results.
