Determination of Mercury Species in Environmental
and Biological Samples
M. Morita, J.
Yoshinaga and J.S. Edmonds
Synopsis: Mercury is released into the hydrosphere, atmosphere and
biosphere as a consequence of natural and anthropogenic processes. It is cycled
in the environment and undergoes transformations of its chemical forms. Although
the number of chemical species encountered in environmental and biological
samples is not large, the range of matrices and the toxicological significance
of mercury, with a consequent need for ultra-trace determination, have resulted
in a considerable analytical literature. Sensitive and selective methods for
mercury determination, micro methods for the determination of mercury species,
the occurrence of mercury species in the various environmental compartments,
and analytical considerations, including the availability of certified reference
materials, are reviewed.
