Abstract

The precise, accurate analysis of environmental materials for their total or partial elemental content is anything but a simple or routine task. There are numerous problems that must be addressed to assure a high quality analysis. The first and foremost problem to be addressed is to determine what is the question that the environmental scientist is really trying to answer and how to customize the analysis to meet that need. Is the scientist asking for a given species of an element, the amount of the analyte associated with a certain phase or fraction of the environmental sample, or would a total analysis answer the correct question? The scope of the phrase “Environmental Materials” is where the problems continue. Most naturally occurring materials and some man-made materials can fall into this classification. The concentration of an element of interest commonly ranges from one part per billion (microgram per kilogram or μg/kg) to the tens of weight percent. There are usually sampling problems in the analysis of environmental samples. These problems could include:
