Anotace obsahu normy

This document specifies the procedure for screening soils for selected elements using handheld or portable equipment for energy dispersive X-ray fluorescence spectrometry (ED-XRF). It covers the application of this screening method to obtain qualitative or semi-quantitative data to assist decisions on a sampling strategy for detailed assessment of soil quality employing laboratory analytical chemical methods.
This document does not explicitly specify elements for which it is applicable, since the applicability depends on the performance of the apparatus and the objective of the screening. The elements which can be determined are limited by the performance of the instrument used, the concentrations of particular elements present in the soil, and the requirements of the investigation in terms of the minimum concentrations of concern (e.g. guideline value).
This document does not provide guidance on how to use the equipment to provide quantitative data for use in detailed site assessments. This document does not cover how the results of multiple determinations are synthesized to address the objectives of an ED-XRF determination.
