Analyses of Heavy Metal Mixtures in the Environmental Media.

The identification and measurement of heavy metals in samples of environmental origin as soil, water, ambient air or from biological objects, is performed at present by different analytical methods and techniques normally in special laboratory conditions. In cases when an express in-field chemical analysis and interpretation of the results is needed, the usual procedures, which assure the quality control of measurement and data collection, are time limited and simplified. The aim is to develop and introduce in general practice reliable methods and techniques for express elemental and isotopic analysis of the envi ronmental media pollution, which would fulfill the measurements at acceptable quality level and would not sacrifice the quality objectives of the analysis because of compromises reasons. A presentation is made here of a small and portable laser mass-spectrometer, whose analytical capabilities are believed to fulfill the requirements for in-field chemical analysis of environmental pollution with heavy metals.
