ATOMIC SPECTROMETRY UPDATE - ENVIRONMENTAL-ANALYSIS

This is the thirteenth annual review published in JAAS of the applicat ions of atomic spectroscopy to the chemical analysis of environmental samples. The format used continues to be similar to that of previous y ears, highlighting the main features of this particular subject. Devel opments in instrumentation are not essentially a feature of this updat e, and so the emphasis is mainly with the establishment of reliable an d robust methods of environmental analysis. The update does; however, focus on the areas of sampling, sample preparation and sample introduc tion in atomic spectroscopy. The most popular areas for development in sample preparation continues to be dissolution/decomposition, separat ion and preconcentration, and solvent extraction, with the emphasis on the establishment of robust and valid methodology. The motives for th is approach are usually being led by the necessity to develop simpler, low cost and safe methods. The importance of trace element determinat ion in environmental analysis reflects the need of industry, governmen t bodies and other interested groups to obtain reliable data as to the level of pollutants in the environment.
