Abstract
The inductively coupled plasma (ICP), when employed as an excitation source in optical atomic emission spec.troscopy (AES), is finding widespread utilization for single and multielement inorganic trace analysis of pollutants. The recent availability of commercial ICP‐AES instrument systems has stimulated applications for the determination of metals and metalloids in diverse materials ranging from air particulates and fly ash to industrial effluents, sewage, and hard, soft, and saline waters. The capabilities and limitations of ICP‐AES for applications in air and water pollution analysis are reviewed, and a number of recent examples presented.
