Book excerpt: The analysis of water, wastewater, sediment, and other matrices for the presence of metals has become a large proportion of the work requested from the typical analytical laboratory. Advances in sample preparation, analytical techniques, and equipment capabilities are occurring at a rapid pace. This report is intended to help the working analyst come to grips with the rapidly expanding numbers of methods and techniques for trace metal analysis. The advances in trace metal analysis have been made in two different areas that are the primary focus of this report: better instrumentation (including atomization, nebulization, optics, and data manipulation) and new and novel techniques of sample preparation (preconcentration, matrix removal, and dissolution). Theses topics are treated in Parts II and III, respectively. As detection limits get lower, contamination and loss of analyte during sample preparation and analysis become increasing significant. This subject is discussed in Part IV. Sources of interference in traec metal analysis, particularly in complex sample matrices that are becoming a larger percentage of the analyst's effort, are discussed in Part V. To aid the analyst with specific analytical problems, a comprehensive bibliography of pertinent literature from recent journals and periodicals is provided in Appendix A. Keywords: Analysis, Atomic absorption, Interference, Ion chromatography, Trace metals.
