This is the fourteenth annual review published in JAAS of the applications
of atomic spectroscopy to the chemical analysis of environmental samples. T
he format used is generally similar to previous years with some alterations
to sub-headings to take account of current trends in the literature. Altho
ugh developments in instrumentation are not rite main focus of this review
they are closely linked to applications as the ability of any new instrumen
t development to measure a determinand at lower concentrations invariably l
eads to its use in the wide variety of matrices studied by the environmenta
l scientist. As well as instrumentation, key parts of the review are the ar
eas of sampling, sample preparation and sample introduction, which continue
to be driving forces for research and publication in the environmental lit
erature. Continuing the trend of last year's review there are an increasing
number of publications on speciation of metals, in which separation techni
ques have been coupled to atomic spectrometry instrumentation, with particu
lar inter est in using the very low detection limits and isotopic informati
on that can be obtained with the nutrient generation of ICP-MS instruments.
The importance of trace element determination in environmental analysis re
flects the need by industry, government bodies and other interested groups
to obtain reliable data on the let el of pollutants in the environment.
