Soil quality. Determination of trace elements in extracts of soil by inductively coupled plasma-atomic emission spectrometry (ICP-AES) Ingestion-build-126766 usability and stability for the1 Scope This International Standard describes the determination of trace elements in digests or extraction solutions from soil by inductively coupled plasma atomic emission spectrometry (ICP AES) for 34 elements (see Table 1). This multi element determination method is applicable to soil extracts obtained with aqua regia in accordance with ISO 11466, with DTPA in accordance with ISO 14870 or other weak extractants, or soil extracts for the
