Specifies a method for the extraction, with aqua regia, of trace elements from soils and similar materials containing less than about 20 % (m/m) organic carbon. Materials containing more than about 20 % (m/m) organic carbon will require treatment with additional nitric acid. The resulting solution is suitable for the determination of trace elements using appropriate atomic spectrometric techniques.
