Soil quality. Chemical methods - Extraction of trace elements soluble in aqua regia Ingestion-build-83346 and the manner of defining1 Scope This International Standard specifies a method for the extraction, with aqua regia, of trace elements from soils and similar materials, prepared according to ISO 11464, and containing less than about 20 % (m m) organic carbon according to ISO 10694. Materials containing more than about 20 % (m m) organic carbon will require treatment with additional nitric acid (see note 8). The resulting solution is suitable for the determination of trace
