ECOLOGY SCREENING AND MAPPING OF HEAVY METAL POLLUTION OF SOILS BY LASER MASS SPECTROMETRY

摘要

The present paper discusses an approach for performing an express ecology in-field screening with the help of transportable laser mass spectrometric system of easy-accessible small and medium soil areas, polluted with heavy metals. Presented are results from a demonstration experiment in which the heavy metals elemental and isotopic data, gathered by the laser time-of-flight mass analyzer are arranged according to the map of the places of soil sample-taking, thus providing a satisfactory evidence of the ecological status of the area in respect to further remediation activities.
